    In the hidden frame and semi-hidden frame glass curtain wall, the silicone structural sealant plays an important role in connecting the panel and the supporting structure. It is very important to the safety of the curtain wall. Therefore, its durability in engineering has attracted much attention.     In addition to the performance of the material itself, the application processes such as design and construction are also very important factors that affect the durability of silicone structural sealants in engineering. Improper use will cause problems such as poor adhesion and insufficient load bearing capacity. Leading to serious safety issues such as the curtain wall glass falling. In order to further standardize the application process of silicone structural sealants from material selection, design to construction, and maintenance, the China Engineering Construction Standards Association "Notice on Printing and Distributing the Second Batch of Association Standards Development and Revision Plan in 2018" (Building Standards Association [2018] No. 030) China Building Standard Design and Research Institute Co., Ltd. is required to take the lead in formulating the “Technical Regulations for the Application of Sealants for Building Curtain Wall Structures” (hereinafter referred to as the “Regulations”) of the China Engineering Construction Standardization Association. The standardization of various links such as quality inspection, promotes the high-quality development of my country's curtain wall industry.     On December 15, 2021, the China Engineering Construction Standardization Association standard "Technical Regulations for the Application of Sealants for Building Curtain Wall Structures" (Draft for Review) (hereinafter referred to as the "Regulations") review meeting was held at the Crowne Plaza Huadu Hotel.     This conference was hosted by China Building Standard Design and Research Institute Co., Ltd., and undertaken by Guangzhou Baiyun Chemical Industry Co., Ltd., the second editor-in-chief of the Regulations, and was held online offline. Gu Taichang, Secretary-General of China Engineering Construction Standardization Association Construction and Municipal Engineering Product Application Branch (CECS/TC49), and review experts such as Wang Hongtao, Du Jiyu, Shi Minxiang, Shi Lian, Zeng Xiaowu, Chen Jun, Xu Wuyi, and Zhu Zhiyuan.     The review expert group listened carefully to the report of the compilation team on the standard preparation work, and conducted a serious review and discussion on the words and sentences of the "Procedures" (drafts for review), the source of data, the determination of indicators, and the adoption of testing methods. Fully affirmed the work of the establishment group, put forward pertinent revision opinions, and agreed that the standard passed the review and reached the international advanced level.     From the beginning of its establishment, BAIYUN has taken leading the healthy development of the industry as its own responsibility, actively leading and participating in the formulation and revision of domestic and foreign sealants and related standards, and has spoken out on the international standardization stage on behalf of the Chinese sealant industry for many times, and has won a wide range of industries. Reputation and influence.     In March this year, Zhang Guanqi, Technical Director of BAIYUN, as the convener of the working group, revised the international standard ISO 13638:2021 Building construction-Sealants-Determination of resistance to prolonged exposure to water ("Building structure-Sealants-Determination of long-term exposure to water") Release implementation. This standard is the first ISO sealant standard to be formulated and revised under the leadership of Chinese experts, and is of great significance to enhancing China's right to speak in the formulation of international standards.     So far, BAIYUN has led or participated in 207 international, domestic, industry and group standards, of which 149 have been completed, including 6 published international standards and 1 international standard under revision, covering prefabricated buildings, Curtain walls, doors and windows, hollow space, interior decoration, rail transit, solar photovoltaic, LED lighting and other fields are the main force to promote the standardization process of the industry. In the future, BAIYUN will join hands with more industry colleagues to continue to move forward on the road of standardization, and create a better future with you.

    In this era, the quality of life has become the pursuit of people, and green environmental protection is paid more attention to by consumers—— Floor? Formaldehyde free; Doors and windows? It should be of high quality; Paint? Want odorless     People have higher and higher requirements for the high-quality development of buildings, and the requirements for the safety and reliability of building curtain wall doors and windows are also increasingly strict. As an indispensable part of doors and windows curtain walls, sealant plays an important role in "small materials play a big role", especially in the fields of doors, windows, curtain walls and interior decoration, The quality of sealant is directly related to people's life quality. With the improvement of economic level, people's requirements for sealant are no longer limited to simple bonding and sealing effect, but also require that the sealant has good environmental protection performance.     So, what is the green environmental protection high quality sealant? First of all, let's take a look at the interpretation of authoritative standards from the state——   01 Interpretation of standards     In 2014, the national mandatory standard GB 30982-2014 "limits of harmful substances in building adhesives" was officially implemented, which put forward detailed requirements for the limits of harmful substances of solvent based, water-based and this type of building adhesives. According to the standard GB 30982-2014 limits of harmful substances in building adhesives, silicone sealant belongs to this type of adhesive, This kind of adhesive requires higher than solvent based and water-based sealant, environmental protection is also stronger. The limit values of harmful substances are shown in the table below: Table 1 Limit value of harmful substances in building adhesives of this type in GB 30982-2014 project index Organosilicon (including MS) Total volatile organic compounds / (g / kg) ≤100 But, just look at this one index, can you explain what is green sealant? Of course not. At present, neutral silicone sealant on the market can be divided into dealcohol sealant and deacetoxime sealant according to the release of small molecules during curing. Alcohol type sealant, the release of small molecules during curing is generally methanol, ethanol (commonly known as alcohol) and other small molecules, while ketoxime sealant, the release of small molecules during curing is generally small molecules of ketoxime such as butanone oxime. From the standard requirements, both belong to organosilicon, and the requirements of "total volatile organic compounds" are the same. So, is there any difference in the effect of releasing different small molecules on environmental organisms? Next, let's make a comparison through experiments—— 02   Volatiles Testing of plant toxicity     Experimental design through the two kinds of sealants in the closed environment on the same plant growth degree, through the biological toxicity to compare the difference of environmental protection between alcohol type and ketoxime type sealant. STEP1 Prepare two groups of potted plants of the same type with two plants in each group, as shown in the figure below; Two groups of potted plants STEP2   The samples of alcohol sealant and ketoxime sealant were made respectively; Just made sealant sample STEP3   Put the sealant sample block and potted plant into the transparent glass tank in turn, and cover the glass plate to form a closed space for observation; Potted plant maintenance environment STEP4   Check the condition of curing for a period of time, and record the changes of plants after 4 days of maintenance and 10 days of maintenance, as shown in Fig. 5 and Fig. 6 respectively 4 days of potted plant maintenance   10 days of potted plant maintenance       Experimental conclusion: it is clear that butanone oxime released during the curing process of ketoxime sealant has obvious toxic effect on plants;The small alcohol molecules released during the curing process of alcohol sealant had no adverse effect on plant growth.From this we can draw a conclusion—— Alcohol based adhesives are more environmentally friendly       It is obvious that ketoximes are more harmful to human body than alcohols. However, ketoximes are considered to have potential carcinogenic risks in Europe and the United States: a substance evaluation of butanone oxime by the Federal Institute for occupational safety and health in Germany shows that the carcinogenicity of butanone oxime to animals is fully verified by rats inhaled with butanone oxime,It was confirmed that butanone oxime was associated with the rapid growth rate of benign or malignant tumors. 03   BAIYUN The founder of alcohol sealant in China     As the founder of silicone sealant industry in China, Bayun has been committed to the innovative research and development and performance improvement of various sealants.In 1992, Baiyun Chemical Co., Ltd. was transferred to the small test technology of silicone sealant from China Chenguang Research Institute. In the same year, Baiyun launched the first silicone sealant in China and the first alcohol sealant ss601 in China, which laid the foundation for the development of domestic alcohol sealant technology,For the latecomers to light a new light to green health.       At present, only in the field of building sealant, Baiyun alcohol sealant products have covered curtain walls, doors and windows and other fields, forming a solution of alcohol type sealing and bonding system in many fields, such as weather resistant sealant, door and window sealant, civil sealant, etc., including various functions of bonding, sealing, and caulking.More healthy, more environmental protection, more green, protect every corner of the city,Quality is achieved by details, and life is built by quality.For users, learning to choose the real green sealant products is responsible for their own lives.Baiyun, empowering beauty.

      As we all know, any product pays attention to what you pay for. As a chemical product used in bonding and sealing of curtain walls, doors and windows, interiors, and industries, the cost of silicone sealants is closely related to product materials, quality, and quality control. Under normal circumstances, most manufacturers will strictly adhere to the bottom line of the enterprise, operate with integrity, and serve the public with high-quality products. However, in the face of the skyrocketing bulk raw material commodity market, some bottom-line companies use inferior raw materials to reduce costs, and even use bad methods such as insufficient packaging and stealing credits in exchange for short-term profits.     Take sealant as an example. What is behind it, what is it that is eager for quick success and ignoring the bottom line? sealant cost competition. Round 1 ▲BAIYUN non-oil-extended formula and a brand oil-extended formula cost comparison     It can be seen from the comparison of the cost of sealants that the cost of oil-extended sealants has dropped to about 60% of the cost of non-oil-extended sealants due to the substantial reduction in the content of silicone polymers. So much cheaper, is such an oil-filled sealant really easy to use? Of course not! Compared with silicone base polymers, white oil has a lower price, but its performance is extremely different. Under normal circumstances, after using inferior oil-extended sealant for a few months to half a year, the filled mineral oil will migrate and permeate out of the sealant, which will eventually cause the sealant itself to become hard, cracked, powdered, oily, and non-sticky. Such series of problems directly bring serious quality problems and even safety hazards to users. Round 2 ▲Comparison of cost between BAIYUN high-quality fillers and additives and a certain brand of inferior fillers and additives     Compared with silicone polymers, the cost ratio of fillers and additives is not high, but as an indispensable catalyst and crosslinking agent for sealants, their quality directly affects whether the sealant can fully react during the production process.     In order to save costs, some companies replace the original mature formula with inferior fillers and low-purity additives in the sealant formula. Due to insufficient response, such sealants are prone to cracking and chalking. In severe cases, the durability of the sealants will be greatly damaged, the service life will be shortened, and an "untimed bomb" will be planted for building safety. Round 3 ▲Comparison of cost between BAIYUN high-quality fillers and additives and a certain brand of inferior fillers and additives     In the past, white oil was used to replenish the number, but now there are recycled materials such as pyrolysis silicone oil and high-boiling silicone oil making waves.     As raw materials for secondary recycling, pyrolysis silicone oil and high-boiling silicone oil have many attributes that are no longer suitable for sealant products. However, due to their lower prices, these two types of raw materials have once again become some of the bottom lines of products that are ignored. The cost control choice for companies that only pursue short-term benefits.     -High-boiling silicone oil is generally made of high-boiling materials obtained by rectification of methylchlorosilane mixed monomers as the main raw material, and then obtained through alcoholysis or hydrolysis. The main component is a mixture of polymethylsiloxanes. Compared with simethicone, a commonly used material in sealants, high-boiling silicone oils have poorer compatibility. When applied to silicone sealants, it is easy to cause chemical analysis, resulting in a decrease in the mechanical properties and bonding properties of silicone sealants.     -Pyrolysis silicone oil is made from dimethyl cyclosiloxane mixture (DMC) obtained by pyrolysis of waste silicone rubber. Compared with the silicone sealant filled with dimethyl silicone oil made of virgin DMC, the production cost of the silicone sealant filled with pyrolysis silicone oil is lower, but it will also cause the mechanical properties of the sealant to deteriorate, especially its aging performance. It is greatly reduced, leading to a quality accident that endangers the safety of the glass bonding and sealing assembly of the curtain wall, and causing great safety hazards to the curtain wall. Round 4 ▲Comparison between the production cost of BAIYUN products and the production cost of a certain brand     Generally speaking, sealant companies mostly use milliliters and milliliters as their purchasing specifications, and the purchaser will purchase according to the consumption budget. However, due to the fact that special measuring instruments are rarely used for measurement, the behavior of insufficient packaging has become a small trick of some manufacturers to "reduce costs". Bits flow into the ocean. Although insufficient packaging may sound innocuous, it is actually a small cost loss for consumers. Especially when applied to certain large-scale projects, it will greatly improve consumers’ Hidden costs. Round 5 genuine guarantee VS wrong goods     Obviously, the MS polyether sealant purchased by the order was quietly replaced with low-end silicone door and window sealant...      The misconduct of the wrong goods, stealing beams and replacing posts has spread among some sealant companies that have lost their bottom line. To sum up:     Behind the low price, it is not necessarily the good quality and the safe future, and it must not be greedy for short-term petty profits, which will cause long-term hidden dangers. Once it breaks out, the gains outweigh the losses.     BAIYUN, always adhering to the corporate mission of dedicating the best products to mankind, provides every consumer with high-quality products at a reasonable price. In the face of such violent fluctuations in the prices of bulk raw materials such as glass, aluminum, and organic silicon, it is particularly important to choose an honest company with a stable and high-quality supply chain. Choosing BAIYUN means choosing high quality. The sealing material itself accounts for a very low proportion of the cost of curtain wall materials. Choosing high-quality sealing materials can obtain a longer mission life and better reputation, while reducing rework, repair and maintenance costs. BAIYUN will protect your safety!  

    In September last year, President Xi proposed at the 75th United Nations General Assembly that carbon peaks in 2030 and carbon neutral targets in 2060. At the same time, this year’s government work report also included “carbon peaks and carbon neutrality” for the first time as a key task. One of the keys to achieving the "dual carbon" goal is the transportation industry     On the one hand, the transportation industry is the main area of global greenhouse gas emissions. And as China's car ownership continues to increase, carbon emissions in the automotive industry will become the focus of the "dual carbon" goal.     On the other hand, there is still a certain gap between China's car ownership per thousand people and developed countries. As the economy picks up after the epidemic and urbanization is gradually improved, the development of new energy vehicles will help achieve "dual carbon". After all, it can be seen from the working principle of new energy vehicles that new energy vehicles have a more obvious effect  on reducing carbon emissions than traditional fuel vehicles. The development of new energy vehicles is ushering in new opportunities under the background of "dual carbon". 01 Power battery thermal management     As the power source for the operation of new energy vehicles, the power battery is undoubtedly the core of the core. Power battery components mainly rely on converting chemical energy into electrical energy to provide a source of power for electric vehicles. at low temperatures, the thickening of the electrolyte causes the movement of the conductive medium to be hindered, and the electrochemical reaction rate and depth of the reaction are reduced, resulting in a decrease in battery capacity. The power battery macroscopically shows the phenomenon of electric vehicles "deficit" in the winter environment. on the other hand, excessively high temperature will cause a series of side reactions inside the battery, which not only affects the battery life, but also poses a safety hazard. it is precisely because of the important influence of temperature on the electrochemical reaction that the power battery is obviously restricted by temperature.     Vehicle chassis space is limited, and battery modules must be closely arranged. However, on the one hand, closely arranged batteries are prone to heat accumulation, and on the other hand, the temperature of the cells in different positions is often not completely the same. therefore, the use of a reasonable thermal management mode to regulate the battery operating temperature and maintain the battery cell temperature consistency in the battery pack is of great significance to the life and safety of the battery pack. especially under the industry trend of pursuing high endurance and fast charging, an excellent power battery thermal management system determines the life and safety of electric vehicles. 02 Application of Polyurethane Thermal Conductive Structural Adhesive     The thermal management system can be divided into air cooling, liquid cooling, phase change cooling, heat pipe cooling, etc. according to the cooling medium. At present, the power battery industry occupies the "center" position undoubtedly the liquid cooling mode. In the liquid cooling mode, the thermally conductive adhesive plays an important auxiliary role. In order to test the thermal conductivity of thermally conductive adhesives, a well-known scientific research institution established a heating model of single cells, simulated and analyzed the heating of battery modules under different discharge rates, and studied and compared the balanced heat dissipation effects of thermally conductive adhesives with different thermal conductivity on lithium batteries.     The research results show that: the higher the thermal conductivity of the thermally conductive adhesive, the more obvious the temperature rise and temperature difference of the battery will be reduced, and the more balanced the battery temperature distribution will be. Because the optimal working temperature band of power battery cells is very narrow, generally between 20-40°C, the heat conduction of the thermal conductive sealant can effectively reduce the temperature of the cells and the temperature difference between the cells, which is useful for maintaining the normal operation of the battery thermal management system. Has a very significant effect.     Different from the performance selection of thermally conductive adhesives in 5G communication base stations (the thermal conductivity is up to 10 W/mK), the thermally conductive adhesives selected in the power battery industry not only need to meet the requirements of thermal conductivity, but also need to be the cost and even the volatile matter are comprehensively considered, so the thermal conductivity is often maintained in the range of 1.2-2.0 W/mK.     However, due to the limitations of material technology, thermally conductive adhesives with higher thermal conductivity at this stage tend to have higher density and higher cost. Battery manufacturers are unable to choose high thermal conductivity (>3.0 W/m.K) silicone products under the trend of large demand for thermal conductive sealant and continuous cost reduction. at the same time, due to the continuous reduction of the design conditions of the structural parts of the battery pack, the thermally conductive adhesive needs to have a higher strength (greater than 10 MPa) bonding and fixing function in addition to the thermal conductivity function. Therefore, the polyurethane thermal conductivity with advantages in bonding strength and economic cost Structural adhesives have become a realistic choice for many battery factories and new energy vehicle manufacturers. 03 BAIYUN power battery polyurethane solution     Follow national policies closely to help achieve the dual-carbon goals. as a leader in the domestic sealant industry, BAIYUN deployed the power battery industry early, and launched PU8262 series polyurethane structural adhesives and PU8592 series polyurethane thermal conductive structural adhesives for power battery structural bonding and thermal conductive structural bonding, which can provide thermal conductivity for power batteries Customized solutions with 0.4-2.0 W/mK and bonding strength of 6-15 MPa.     At present, with the continuous advancement of the dual-carbon plan, the new energy vehicle industry has ushered in new outlets. With more and more consumers pouring into the new energy vehicle market, the technological level of new energy vehicles is bound to be innovated, and the sealant that combines bonding, sealing, heat conduction, shock resistance and other functions in new energy vehicles is also proposed new requirements.     Dedicating the best products to mankind, BAIYUN always insists on providing every consumer with the industry's top sealing system sealant solutions. as the top supplier of domestic sealing and bonding solutions, BAIYUN will surely empower the industry to develop a new ecology with better products and services, and work with many colleagues to promote the technological progress of the new energy automobile industry and help achieve "carbon peak" The goal of “carbon neutrality” is to build a safe, green, healthy and sustainable future.  

What is the current situation of the global economy and manufacturing industry? Half is “sea ”and another is flame.     The downstream of the industry lacks money, cores, and consumption; upstream lacks coal, electricity, and various raw materials...     what's more serious is that the US dollar has begun to impact the global economy, coal prices hit a record high; oil prices may reach 100 US dollars per barrel; natural gas prices soar all the way, and Europe is about to experience the coldest and most expensive winter...     As a result, some people predict that the global economic crisis and large-scale inflation will hit all-out soon...     At this moment, China's "30·60" dual-carbon target has been set! This is a ruin of China's technological upgrading, a calmness from the beginning to the end of the industry, and a script swap in the game of great powers. The dual-carbon goal not only presses the fast-forward button for the energy transition process, but also opens up a new ecology for business and the entire society. The carbon-based era represented by fossil energy is changing to the silicon-based era represented by new energy and new materials. Transformation and upgrading, the industry boom is coming.       Under the background that the global economic landscape may be about to undergo major changes and in the environment of the new industry ecology in the silicon-based era, competition and innovation always coexist. What kind of iterative upgrade does the strategic thinking of the silicone industry chain companies need to make? How to achieve innovation empowerment and sustainable development? At the same time, what kind of adjustments are needed to the internal ecology of the enterprise to break through the bottleneck of industry development? Is the global economy facing a major crisis? In the silicon-based era, who will lead?   Co-existence, building a new ecosystem for industry development     Since the beginning of this year, the silicone industry is experiencing the biggest storm in history, and we are more deeply aware of the meaning of a community of destiny than ever before. Under the new crown epidemic and the increasingly complex international political and economic situation, everyone has a deep sense of uncertainty and has explored and researched ways of survival. Co-existence is the focus of discussions on related topics.     No matter how powerful a company is today, no matter what stage of strong development it is in, or even what advantage position it is in now, unless the logic behind the business operation has been transformed from "competition" to "cooperation", it will be impossible to obtain an inexhaustible driving force for sustainable development. Companies must ensure that they build or join a "symbiotic system", find their indispensable positioning, and form a value symbiosis with the upstream and downstream of the industrial chain, so that they are able to cope with uncertainty and achieve coordinated development.     What is certain is that for some companies that only care about their own interests and ignore the health and high-quality development of the industrial chain, they may snatch the market in the short term through some means that ignore the bottom line, but in the long run, this will be right. A fatal disaster for the industry, for users, and for oneself.     Take sealant companies as an example. As the prices of raw materials continue to rise, competition and cost pressures continue to heat up. Many companies turn their heads on quality when they reach the top of their innovation. Boiling material and filling with inferior fillers. In the short term, it may appear that it only used some means to touch the bottom line to grab the market, but in the long term, this will be a fatal disaster for the industry, users, and own company. It is foreseeable that it will eventually the result will only be notorious in the entire industry chain. Innovation and empowerment, breakthrough industry development bottlenecks     An industry that has the courage to innovate is the land of hope; an enterprise that has the courage to change can have a bright future.     The silicone industry has become an important basic and leading industry for the high-quality development of China’s economy due to its high technical content, high added value, and strong compatibility with various sectors of the national economy. Its development is directly related to China Innovation or healthy development of strategic emerging industries. At present, the technological development of the silicone industry is advancing by leaps and bounds, and the ability of independent innovation has been greatly improved. However, at the same time, there are still “stuck necks” in key areas, and the issue of “strong foundation” for industrial upgrading is imminent. In the context of "striving to become the world's science center and innovation highland", innovation empowerment has never had such a profound impact on the future and destiny of the country and the people's life and well-being as it does today. From an economic power to a science and technology power, companies play an important role. For silicone companies, it is our mission and responsibility to promote development with innovation, benefit the people with innovation, and change the world with innovation.     If the key core technology is not available, it can't be bought, it can't be negotiated." In the journey of a technological power, it is even more necessary for the entire silicone industry chain to work together to break through the bottleneck of industry development. Good creators help from heaven, have hard cores, and bravely innovate. No matter where we go, we don't panic in our hearts. Persist in long-termism and build a great company     All attempts and explorations are in the process of lengthening time and obtaining definite answers in an uncertain world.     To talk about long-termism, it is a value thinking that the silicone industry should most uphold. From the development of new products in 3-5 years to the launch and to the innovation and upgrading of existing products in 2-5 years. From the positioning of the target market， to becoming the market leader. From brand building to industry leader brands, this is a relative ，a long and continuous accumulation process.     Being able to endure loneliness and risks, while also being able to see the direction clearly are the common characteristics of companies that stick to long-termism. In the new era full of dangers and opportunities, facing such many uncertainties, one can only penetrate the noise and be friends with time.     Great companies are always simple and monotonous, and there are no exciting events, because all possible crises have long been foreseen and have become routine work through solutions."     Only through the cycle can we wait for the coming years to be quiet, and only when the turmoil does not fall can we reap the fruits. In fact, every choice is an important value judgment, and every judgment comes from people's underlying beliefs. With the rapid development and change of society, economy, technology, and humanities, we must be especially vigilant against opportunism.     Long-termism is not only a methodology, but also a value. Flowing water does not compete for the first place, but the contention is endless. No matter what kind of work or career you are engaged in, as long as you focus on the long-term and focus on value, you will surely be able to withstand the test of time and find the right to meet the challenge.     In 2021, the disturbance is coming to an end, but in terms of the global structure and the social ecology of corporate development, there are still many things we are not sure about. We are not sure, when will the end of the new crown epidemic come? We are not sure, what is the next technological innovation to lead the world? We are not even sure, is this an opportunity or a challenge?     The answer lies in the heart of every fellow in the industry chain.     The future is an era of explosive demand. Whoever can lead the demand will be the leader of the future. And any industry related to our better life requires ingenuity and "long-termism" persistence.     In this journey of adhering to the long-term doctrine, BAIYUN will walk with you and empower the beauty.

    2021 has entered the second half of the year. The organic silicon raw materials standing on the cusp of the storm have risen for six months in a row, and the rise seems to have no limitation!     The tide of price increases has not yet eased, and the tide of out-of-stocks has quietly arrived. At the present, with the rising prices of raw materials and labor, and the superimposed impact of the new crown epidemic, it will undoubtedly bring great pressure on the operation of middle and downstream enterprises.     What do you think about the escalation of many contradictions in the cusp of turmoil? How would you choose? The supply chain system embarks on a new track     Throughout the industry, a good supplier management system has become the basis of competition. Industry competition has already expanded from competition between individual companies to competition across the entire supply chain. The recent price hikes have deeply disturbed the silicone market, causing every downstream rubber company to cautiously calculate how to effectively control costs. Undoubtedly, sealant companies cannot stand, and rising tides are inevitable. In the turbulent era, some users are worried. On the one hand, they must ensure the stability of the supply, and on the other hand, they are extremely worried about the price of the product. However, all the contradictory escalation points all indicate that it is precisely the market that is changing nowadays, which calls for an urgent need for high-quality, high-efficiency supply chains. when "out of stock" and "price increase" become the key words of the market, choosing a supply chain system that is responsible, has common values, has a win-win concept, and has strong technical precipitation will be a win for the company in the harsh market environment.     At the same time, a high-quality high-quality supply chain means that companies can rely on the chain system to have the confidence to ensure stable product output and stable product quality. Is your supply chain partner a high-quality, high-quality qualified supplier? value and price are fully matched     In the face of a treacherous market, it is difficult to turn the tide on its own. The market calls for a high-quality supply chain. Enterprises and users themselves must think about how to achieve more effective resource replacement, seek "stability" in the "chaos", and strive to protect the supply chain. Stable output and stable quality of the links can be stable and far-reaching, and empower the sustainable development of the enterprise. Perhaps we can find some answers in the pace of social change. the country’s macro-economy has shifted from the pursuit of GDP growth to the pursuit of stability and rationality in sustainable development; Economic development has shifted from a high-energy-consuming, non-green, extensive growth mode to an intensive growth mode focusing on conservation and fine management; the economy and society have been irregular from the beginning followable chaotic and disorderly turn to laws, regulations, and regulatory systems that are constantly improving and orderly... What do these changes mean to enterprises? It means that you can no longer just want to waste energy and destroy the environment for your own interests; it means that you can no longer dream of becoming rich overnight without hesitating to betray public morals and conscience and despise the law...     Everyone who is in the torrent of reforms should clearly recognize these changes, and the enterprises and entrepreneurs who are the cornerstones of the economy and society should be the foresighters of the reform trend. The experience of many successful companies continues to tell us that abandoning speculation and short-sightedness, peace, stability, focus, and adherence to long-termism are the mentality that today's companies should participate in market competition.     For a normal operating company, everyone hopes to have benefits and profits. Where do the benefits and profits come from? Of course it is cost control, but cost control is not blindly reducing the consumption of raw and auxiliary materials or even reducing the quality of raw and auxiliary materials, not blindly reducing spare parts inventory and equipment maintenance costs, let alone reducing the number of laborers, increasing labor hours, or even reducing Workers’ wages. In the long run, product quality and the sustainable development of the supply chain will inevitably not be guaranteed, and leaving the "quality" to pursue the so-called low "cost" is tantamount to self-destruction! What is a real high-quality product? Its core essence must be: the value and the price fully match, even the value is far greater than the price. The continuous increase in labor costs and material costs puts high demands on the selection capabilities, price negotiation capabilities, and construction supervision and operation capabilities of upstream and downstream suppliers in the industry chain. The starting point for all this requires companies to be willing to devote everything they can to quality. Therefore, the old adage of "you pay for what you pay for" is still the most plausible saying today. The price of products with excellent product quality will naturally not be too low. At a time of turmoil when raw material prices are rising wildly, is low-price competition a real skill or is it a disaster to the industry? Do you care more about the value of the product or the price? precipitate with heart, make a good product Looking at the domestic investment boom in recent years...every boom, companies are closely following the boom, and when the market matures and the heat recedes, how many companies are still fighting steadily? Some real estate developers maliciously breached the contract due to fluctuations in the property market, leading to the project being unfinished... Some companies unilaterally tear up the contract at the sight of unprofitable... Some industries are distorted by these turbid normalities and eventually go to extinction...     In this process, how many companies are precarious? How many well-known brands have disappeared?     The industry has entered a stage where high competition and low profits coexist. It will also face a new situation where the strong will become stronger and the weak will be eliminated. In this round of reform, problems, contradictions and opportunities have been revealed together. However, no matter what era, service and quality are the most important capital for enterprise development, and good products need to be carefully polished and carefully precipitated. Can withstand loneliness, withstand temptation, and withstand the bottom line, BAIYUN knows this. 1 Insist on using 100% raw materials BAIYUN’s selection of suppliers and raw material product judgments need to go through a three-trial and three-review review and inspection process. It resolutely refuses to fill or use inferior raw materials such as white oil, high boiling materials, and cracked materials. It also requires all raw materials to be used in each application stage. Have good performance. 2 "Strict" production process control Every piece of BAIYUN brand sealant needs to go through 58 procedures of strict inspection from raw material warehousing, discharging, sub-assembly, and finished product delivery. The production line is monitored for 24 hours, which is the first to realize the key to the quality control of each product from the source to the end. Point monitoring, analysis, control and prevention ensure that the sealant products that reach customers have excellent performance. 3 BAIYUN whole-process service From return visits to existing curtain walls to engineering application guidance, from extreme weather project response to technical exchanges and skills training, BAIYUN’s first "full-process service" system has effectively penetrated all aspects of consumer use, providing "moisturizing materials" for all links in the industry chain. "Silent and silent" high-quality service helps customers make good use of good products and gives customers the most solid technical backing.     In the face of rising raw material prices, BAIYUN will never resolve cost pressures by reducing product quality and service levels.

    In the context of global “carbon neutrality”, the combination of multiple factors such as the surge in green investment, the tight supply caused by the strong demand for raw materials, and the mismatch of upstream and downstream capacity expansion in the industrial chain, have driven the price of organic silicon raw materials to skyrocket. Since the second half of 2021, the price of domestic organic silicon raw materials has soared, hitting a new high in recent decades. At the same time, the share prices of listed companies in the silicone sector have repeatedly hit record highs... Faced with the great change, you need to be more rational     People often use "standing on the great change " to describe the rapid development of an industry, and often use "pigs to fly" to describe the "beings of all beings" trapped in the mud and sand under the tide of the industry. In fact, in the industrial chain relationship of co-prosperity, symbiosis, and interdependence, one party's substantial price increase will inevitably affect the production and operation of the other party and exacerbate the tension between supply and demand in the entire industry chain.     In the future, with the continuous increase of investment in new energy, as an important part of the national strategic emerging industry and the new material industry, it is also an indispensable supporting material for other strategic emerging industries. The demand for silicone will further increase, and the price may increase. It has been in a high position for a long time. In other words, industrial coordination and adjusting the balance of supply and demand will become a major challenge facing the industry in the long term. In this supply-demand game, if the industry development interests are not the prerequisite, no one can be a winner.     Behind the soaring prices, putting aside the hustle and bustle of capital and the market, the center of attention should return to the discussion of the sustainable development prospects of the industry. From basic industries to national strategic emerging industries, from independent innovation to today's veritable organic silicon producer, China's organic silicon industry is hard-won and needs a gradual process of perfection and maturity. The high-quality development of the industrial chain needs precipitation, and companies need to jump out of short-term interests, clarify and return to the essence of business, and create real value.     The more you get to the wind, the more companies will do the right things, the hard things, the long-term things, and the things that take time to accumulate. Only when you sink your heart can you have a chance to cross the storm. Let this industry be less impetuous and more heavy to meet public expectations; let the market be less crazy and more rational, otherwise, once the wind stops, the whole industry chain will be buried after all. Faced with the great change, you need to stick to a sense of responsibility     For a normal operating company, everyone hopes to have benefits and profits. Where do the benefits and profits come from? Of course it is cost control, but cost control is not blindly reducing the consumption of raw and auxiliary materials or even reducing the quality of raw and auxiliary materials, not blindly reducing spare parts inventory and equipment maintenance costs, let alone reducing the number of laborers, increasing labor hours, or even reducing Workers’ wages. In the long run, product quality and the sustainable development of the supply chain will inevitably not be guaranteed, and leaving the "quality" to pursue the so-called low "cost" is tantamount to self-destruction! The great change makes everyone more anxious, but each era has its breakers. They have withstood the baptism of the market and the forging of volatility. Why can they succeed? The standard answer is simple and complex, that is "Sense of Responsibility".     Perseverance to the sense of responsibility is a self-reflection of the society as a whole. What is needed is that the company is in the current predicament and always adhere to the creation of commercial value and social value. What is needed is stronger corporate innovation and driving capabilities. I hope to find those brands and companies that adhere to the sense of responsibility in the changing tides, and then build a "coordinate system" that adheres to ingenuity and long-termism, so that this kind of respect for love and life, and innovation that have been ignored The continuous pursuit of the company has once again become the universal value of the times. Faced with the great change, you need to make the right choice     In the process of our personal development, from ordinary to excellent and outstanding, we are continuously pushing a huge and heavy flywheel. In this process, there is no single thing that determines the effect together, nor will there be lucky mutations and momentary miracles, but there are only clear ideas and unswerving correct choices. Right now, when "out of stock" and "price increase" become key words in the market, Maybe you are still thinking, when will the price of organic silicon raw materials rise to the top? Perhaps you are still thinking about whether the market will gradually return to fundamentals? Perhaps you are still thinking about how to seize the opportunity in the tremendous changes brought about by this tuyere? ... No one can say when the price rising will end, but after the price rising, when the market and users should accurately grasp the situation and make the right choice, they must choose. when "out of stock" and "price increase" become the key words of the market, choosing a supply chain system that is responsible, has common values, has a win-win concept, and has strong technical precipitation will be a win for the company in the harsh market environment. The magic weapon to win the market.   The silicone industry has become a new track, what are you thinking about? When you stand on this new track that has received a lot of attention, BAIYUN is willing to join hands with colleagues in the silicone industry chain, Do not forget the original intention, forge ahead!

      2021 has entered the second half of the year. The organic silicon raw materials standing on the cusp of the storm have risen for six months in a row, and the rise seems to have no limitation!     The tide of price increases has not yet eased, and the tide of out-of-stocks has quietly arrived.     At the present, with the rising prices of raw materials and labor, and the superimposed impact of the new crown epidemic, it will undoubtedly bring great pressure on the operation of middle and downstream enterprises.     What do you think about the escalation of many contradictions in the cusp of turmoil? How would you choose? The supply chain system embarks on a new track     Throughout the industry, a good supplier management system has become the basis of competition. Industry competition has already expanded from competition between individual companies to competition across the entire supply chain. The recent price hikes have deeply disturbed the silicone market, causing every downstream rubber company to cautiously calculate how to effectively control costs. Undoubtedly, sealant companies cannot stand, and rising tides are inevitable. In the turbulent era, some users are worried. On the one hand, they must ensure the stability of the supply, and on the other hand, they are extremely worried about the price of the product. However, all the contradictory escalation points all indicate that it is precisely the market that is changing nowadays, which calls for an urgent need for high-quality, high-efficiency supply chains.     when "out of stock" and "price increase" become the key words of the market, choosing a supply chain system that is responsible, has common values, has a win-win concept, and has strong technical precipitation will be a win for the company in the harsh market environment.     At the same time, a high-quality high-quality supply chain means that companies can rely on the chain system to have the confidence to ensure stable product output and stable product quality. Is your supply chain partner a high-quality, high-quality qualified supplier? Value and price are fully matched     In the face of a treacherous market, it is difficult to turn the tide on its own. The market calls for a high-quality supply chain. Enterprises and users themselves must think about how to achieve more effective resource replacement, seek "stability" in the "chaos", and strive to protect the supply chain. Stable output and stable quality of the links can be stable and far-reaching, and empower the sustainable development of the enterprise.     Perhaps we can find some answers in the pace of social change. the country’s macro-economy has shifted from the pursuit of GDP growth to the pursuit of stability and rationality in sustainable development; Economic development has shifted from a high-energy-consuming, non-green, extensive growth mode to an intensive growth mode focusing on conservation and fine management; the economy and society have been irregular from the beginning followable chaotic and disorderly turn to laws, regulations, and regulatory systems that are constantly improving and orderly... What do these changes mean to enterprises? It means that you can no longer just want to waste energy and destroy the environment for your own interests; it means that you can no longer dream of becoming rich overnight without hesitating to betray public morals and conscience and despise the law...     Everyone who is in the torrent of reforms should clearly recognize these changes, and the enterprises and entrepreneurs who are the cornerstones of the economy and society should be the foresighters of the reform trend.     The experience of many successful companies continues to tell us that abandoning speculation and short-sightedness, peace, stability, focus, and adherence to long-termism are the mentality that today's companies should participate in market competition.     For a normal operating company, everyone hopes to have benefits and profits. Where do the benefits and profits come from? Of course it is cost control, but cost control is not blindly reducing the consumption of raw and auxiliary materials or even reducing the quality of raw and auxiliary materials, not blindly reducing spare parts inventory and equipment maintenance costs, let alone reducing the number of laborers, increasing labor hours, or even reducing Workers’ wages.

The sealant industry, at the most dangerous time...     Since 2020, In response to the epidemic, many countries have introduced various stimulus policies to support economic development. Due to the over-issue of the US dollar currency, Inflation has intensified and spread radiation to the world, leading to an overall surge in global commodity prices, including organic silicon raw materials. In the first half of 2021 alone, Organic silicon raw materials rose by 50%. The price not only surpassed the peak season of last year, but also approached the highest record in history once again.     Under the huge cost pressure, the most dangerous thing is not price increases, but some companies, in exchange for short-term self-interest, sacrifice quality to "reducing costs and increasing efficiency" behavior is still common. some behavior that originally appeared only in low-end civilian rubber manufacturers and the civilian rubber market have spread to the field of curtain walls, doors and windows involving construction safety, and large sealant manufacturers—— use cracked feed use high boiling material oil-filled sealant reduce the content of 107 sealant use poor quality fillers lack of weight ...     Take the price of raw materials as an example. According to a recent report by a media platform in an industry, the price gap between high-quality raw materials and cracked materials is obvious.     According to professionals from some raw material manufacturers, if cracking materials or high-boiling silicone oil are used as raw materials, the cost of production formulations will be greatly reduced.     Many such "black-box operations" may be just adjustments to business strategies for companies, but behind the low price is not necessarily good quality. Low-quality and low-priced products bring more sealant cracking, water leakage, and bonding. The frequent occurrence of many problems, such as failures and sealing failures of insulating glass, and the uncertainty of the outbreak of many long-term hidden dangers in the future. The sealant industry, at the most dangerous time...     With the endless stream of price increases, some sealant companies have always adhered to the bottom line of ethics and quality, but some manufacturers have chosen to pursue immediate benefits and eagerly produce low-quality products with the symbol of "cost-effectiveness". " Gradually confusing the minds of users, leading to a large number of low-quality sealant products in the current building curtain wall doors and windows market, and safety hazards can be seen everywhere. The original intention is easy to get, but it is always difficult to keep. To achieve the high-quality development of the building door, window and curtain wall industry, it takes generations of people to work hard. Especially in the building door, window and curtain wall industry, the selection of high-quality products has become a rigid demand for urban safety construction. BAIYUN will work together to build a high-quality "ecological supply chain" taking safety as the foundation, forging ahead, has applied for more than 330 patents so far, edited or participated in the compilation of more than 190 international, domestic and industry standards; with innovation as the source, it has repeatedly broken through the industry’s barriers to solve China’s strategic new materials and make good products with real materials, pay attention to user value, be responsible for products and consumers, inject new impetus into the rapid and healthy development of your business, and empower your beauty. ▪ Create a 50-year durability test first since 1996, BAIYUN has successively established 50-year limit test observation points in Guangdong, Xinjiang, Florida, Arizona and other places, covering various test environments such as high temperature, high humidity, and drought, and regular sampling and testing to obtain real conditions. ▪ The industry takes the lead in introducing 10 major management systems and various product certifications Adhering to the "lean and perfect" quality concept, BAIYUN has been actively introducing various management systems and product certifications.

  Since China's first subway was officially put into operation in Beijing in 1971, the subway has been an indispensable part of urban transportation, effectively solving the problem of excessive crowds caused by obvious agglomeration effects in big cities.   However, the development of the subway has not been smooth sailing.   In the early days, there were no barriers between the subway platform area and the track area. Cases of delays in operations or even accidents due to factors such as people falling off the track or jumping off the platform were often reported in the news. As the urban population continues to increase, the subway has the characteristics of large passenger flow, short departure intervals, and short staying time at the station. Without any safety guarantee, a large number of crowded passengers are influx. If the subway platform does not have corresponding measures, Accidents falling into the track will greatly increase, and the piles will be shocking. In order to reduce the chance of such tragedies, in 2002, Guangzhou Metro Line 2 used an advanced screen door system in the subway for the first time. So far, subway screen doors have blossomed everywhere in the subways of major cities. Nowadays, subway screen door systems have almost become one of the standardized projects in subway construction. Subway Screen Door   The subway screen door is a high-tech product integrating materials, machinery, electronics and information science, including top boxes, fixed doors, sliding doors, emergency doors, load-bearing structures and thresholds. Among them, the toughened glass and stainless steel frame of the fixed door, and the toughened glass and stainless steel load-bearing structure of the sliding door are all bonded and sealed with high-performance sealant. Due to its high requirements for safety, subway screen door sealing and bonding often learn from traditional glass curtain wall bonding and sealing methods and adopt high-performance silicone sealant, which helps to ensure the safety of the screen door glue under the condition of toughened glass.   As China's top adhesive solution provider for bonding and sealing systems, BAIYUN has been deeply involved in the field of transportation equipment for many years, and its adhesive solutions for subway screen door bonding and sealing systems have been well received by customers. This product series is specially designed for the bonding and sealing of subway screen doors and has excellent weather resistance.   After the artificial accelerated weathering test, the physical and chemical properties of the sealant have not changed significantly. For subway applications, it has a longer service life and can provide effective guarantee for the long-term safety of subway screen doors.   Thanks to high-quality products and professional full-process services, in recent years, the BAIYUN brand special sealant for subway screen doors has won the bid for Ningbo Metro Line 4, Foshan Metro Line 2, Guangzhou Metro Line 6, Dalian Metro Line 2, etc. Numerous subway line projects have been well received in the application of subway projects in major cities, contributing to the construction of beautiful cities and the better life of the people.
