01 Packaging and storage of sealants Since sealants are chemical products, the curing mechanism is to react and solidify when encountering moisture. When soaked in water, the outer packaging of sealants can only play a limited barrier role. Therefore, in summer, sealants should be stored in a relatively high, ventilated, and cool place to prevent the sealants from being soaked in rain or even in extreme weather, which will affect the shelf life of the product and cause curing problems in the product packaging. The sealants soaked in water should be moved away from the soaking environment as soon as possible and transferred to a dry and ventilated room. The outer packaging carton should be removed, the surface should be wiped dry and placed indoors for use as soon as possible. 02 Correct method of sealant application Before application, please pay attention to the following: The ambient temperature requirements for the use of Baiyun brand silicone sealant products are: a clean environment with a temperature of 4℃～40℃ and a relative humidity of 40%～80%. In environments other than the above temperature and humidity requirements, it is not recommended for users to apply sealant. The outdoor temperature is high in summer, especially for aluminum curtain walls, where the temperature is even higher. If the ambient temperature and humidity are not within the recommended range, it is recommended to conduct a small area of ​​sealant application test on site and conduct a peeling adhesion test to confirm that the adhesion is good and there are no adverse phenomena before using it on a large area. During construction, please follow the steps below: 01 Construction sequence of structural sealant (structural sealant for curtain wall, two-layer structural sealant for hollow, etc.): 1. Clean the substrate The temperature is high in summer, and the cleaning solvent is easy to volatilize. Attention should be paid to the impact on the cleaning effect. 2. Apply primer (if necessary) The temperature and humidity are high in summer, and the primer is easy to hydrolyze and lose its activity in the air. Attention should be paid to injecting sealant as soon as possible after applying the primer. At the same time, it should be noted that when taking the primer, the number and time of contact between the primer and the air should be reduced as much as possible. It is best to use a small turnover bottle for packaging. 3. Sealant injection After the sealant is injected, the weather-resistant sealant cannot be applied immediately on the outside, otherwise, the curing speed of the structural sealant will be seriously reduced. 4. Trimming After the sealant injection is completed, trimming should be carried out immediately, which is conducive to the contact between the sealant and the side of the interface. 5. Recording and marking After the above process is completed, record and mark in time. 6. Maintenance Units must be maintained for a sufficient period of time under static and stress-free conditions to ensure that the structural sealant has sufficient adhesion. 02 Construction sequence of weather-resistant sealants and door and window sealants: 1. Preparation of glue joints The foam rods in contact with the sealant should remain intact. The temperature is high in summer, and if the foam rods are damaged, it is easy to cause blistering; at the same time, attention should be paid to the compatibility of the substrate and the sealant. 2. Clean the substrate The glue joints should be cleaned in place to remove dust, oil, etc. 3. Apply primer (if necessary) First, make sure that the surface of the sealant joint substrate is completely dry. In summer, the temperature and humidity are high, and the primer is easy to hydrolyze and lose its activity in the air. It should be noted that the sealant should be injected as soon as possible after the primer is applied. At the same time, it should be noted that when taking the primer, the number and time of contact with the air of the primer should be reduced as much as possible. It is best to use a small turnover bottle for packaging. 4. sealant injection There are more thunderstorms in summer. Note that after the rain, the sealant joints must be completely dry before injecting sealant . 5. Repair The temperature is higher in summer, so the repair time is shorter than in other seasons. Repair should be done immediately after the injection is completed. 6. Maintenance In the early stage of maintenance, large displacement is not recommended.

On February 7, 2024, China’s fifth Antarctic research station, Qinling Station, opened. The Antarctic research station is located in the Ross Sea area of ​​Antarctica, filling the gap in my country's research in this area. Those who stick to the Antarctic together with the Qinling Station, Not only researchers from China, There are also various construction materials and scientific research materials made in China. Among them, Baiyun Technology is the only sealant supplier for the Qinling Station project. Production of SS811-LM (low modulus) silicone weather-resistant sealant Also invested in the construction of Qinling Station, Conquer the cold and challenge the limits!   The Qinling Station has a construction area of more than 5,000 square meters. The main body of the station is designed in the shape of the Southern Cross constellation. The design concept is derived from the Southern Cross navigator used by the Chinese navigator Zheng He when he sailed to the Western Ocean. This is my country’s fifth Antarctic scientific research station, the third Antarctic annual research station, and the first research station facing the Pacific sector.   The Qinling Station mainly includes command and dispatch, marine laboratory, personnel accommodation, office meetings, catering activities, material and vehicle maintenance and storage, communication support, water treatment, garbage disposal, sample room, equipment room, field support center, data center, etc. , is a new generation of scientific investigation platform with intensive space and complete functions. The construction of Qinling Station is quite challenging. The Antarctic environment is extremely harsh, and the Qinling Station is located in one of the worst climate environments in Antarctica. Super strong, super dry, and super cold offshore winds have brought great difficulties to project construction. At the same time, in order to protect the Antarctic environment as much as possible, the construction process of the Qinling Station requires the concept of "green inspection" throughout the entire process, to achieve energy saving, water saving, material saving, resource conservation and environmental protection as much as possible.       Taking into account the construction conditions in extremely cold environments and the requirements to protect the Antarctic environment, the construction of Qinling Station adopted a prefabricated and modular construction system, which can achieve rapid construction within a short window period. According to the builder of the scientific research station, the Qinling Station has more than 1,100 curtain wall panels. Not only are they large in number, but also because they are all modularly produced, the requirements for installation accuracy are very high.   Extremely cold application environments have stricter requirements on the displacement and deformation tolerance of silicone sealants. Therefore, in the construction of this scientific research station, SS811-LM (low modulus) silicone weather-resistant sealant provided by Baiyun Technology was finally selected for the bonding and sealing of the aluminum panel curtain wall. This product is a low-modulus product of Baiyun Technology and has a 50-level displacement capability. Under the same deformation, the internal stress is much lower than that of high-modulus products. It has 100% tensile deformation at low temperature -50°C. The lower stress is 0.41MPa, which is much lower than 0.91MPa of a high-modulus product, which can ensure long-lasting sealing of joints at low temperatures. At the same time, this product meets the requirements of green environmental protection in terms of raw material selection and other aspects, minimizing pollution to the Antarctic environment.

The food safety of an electric kettle is closely related to its composition. An electric kettle is mainly composed of a kettle body, a spout, a lid, a heater and a handle. The body, spout, and lid are generally made of stretched aluminum, and the handle is made of heat-resistant plastic. The electric heater is a steel pipe or stainless steel pipe bent into a circle. The electric heater is installed at the bottom of the kettle and fastened with nuts. A heat-resistant rubber gasket is added between the electric heater and the kettle wall to make the kettle sealed and water-tight. At the same time, silicone sealant is generally used to bond the kettle body and the heating plate as well as the handle and the bottle body. Therefore, in order to ensure quality and food safety issues and prevent food contact materials from harming consumers' health, the adhesive materials used must pass corresponding test certifications and obtain qualified product test reports. Currently, for silicone rubber products, the more common domestic and foreign food-grade standards and certifications are: GB 4806.11-2016, FDA certification and LFGB certification. 01 National standard The food-grade testing standard for silicone materials in my country is GB 4806.11-2016 "National Food Safety Standard for Food Contact Rubber Materials and Products". The measurement items include: sensory test, heavy metal content (in pb), potassium permanganate consumption, total migration (using 4% acetic acid, 10% ethanol and 50% ethanol as simulated solution), etc. 02 FDA certification FDA is the abbreviation of the United States Food and Drug Administration. It is the highest law enforcement agency in the United States specializing in food and drug administration. Food, food containers, medicines, etc. certified by the FDA are safe and effective for the human body. In the United States, substances used in food packaging materials are regarded as indirect additives and are included in the food additive safety regulatory system. The management regulations for silicone rubber products suitable for food contact are mainly the 21 CFR 177.2600 regulations in the US FDA, which regulate For silicone rubber products used in food contact, the formula and vulcanization conditions are clearly specified: it is required to measure the total extraction amount of silicone rubber in distilled water and n-hexane. 03 LFGB certification The full name of LFGB is "Law for the Administration of Food, Tobacco Products, Cosmetics and Other Daily Necessities". It is the most important basic legal document in food hygiene management in Germany and is the guideline and core for the formulation of other special food hygiene laws and regulations. For silicone rubber, the German Federal Institute for Risk Assessment BfR has formulated food-grade standards for silicone rubber. Daily necessities that come into contact with food must pass testing. Only if they meet the relevant standards and requirements agreed in Articles 30 and 31 of the German Food and Daily Necessities Act can they obtain an LFGB test report issued by an authorized agency, proving that they do not contain "Products of Chemical Toxic Substances". The main test items for silicone rubber products include: total migration (deionized water, 3% acetic acid, 10% ethanol), peroxide value test, heavy metal content (calculated as Cd, Pb), total organic volatile matter, polycyclic Aromatic hydrocarbon content, etc.   BAIYUN, empowering beauty picture Committed to safe, green, healthy and sustainable development, BAIYUN continues to explore in this field and currently has a variety of bonding, sealing and thermal conductivity solutions that can meet the diverse needs of the market: 01 Single component SMG261 series Purpose: Sealing and bonding of electric kettle heating plate and glass, circuit board covering, kettle lid sealing, etc. Product Features: ◆Environmentally friendly products, no solvents; ◆Single component, neutral room temperature curing, no heating required, fast curing speed; ◆Good transparency, components coated on the PCB circuit board are clearly visible; ◆Good adhesion to glass, metal, PC, PCB and other materials; ◆Excellent waterproof, moisture-proof and dust-proof properties; ◆Excellent performance in anti-salt spray, anti-aging, anti-shock, anti-leakage, anti-corrosion, anti-mildew, and anti-loose parts; ◆Excellent insulation; ◆Excellent weather aging resistance, aging resistance, UV resistance, and ozone resistance; ◆Excellent high and low temperature resistance.

Winter is approaching, with the gradual increase of cold air activities; the temperature across the country has begun to drop. According to the latest weather forecast, in the next few days, the eastern part of the northwest, northeast, North China, Huanghuai, Jianghan and other places will drop 4 to 6 degrees, and the maximum temperature drop in the central and eastern Inner Mongolia will reach 8 ~ 10 degrees. And the first snow has fallen in Changchun and other places, covering the city with a new coat. The colder the winter, the more safety and quality of the building is needed to shelter the people. Today, let's master the use of silicone structure sealant, a building structure adhesive sealing material, and guard the building safety!   The ambient temperature is very low in winter, the following problems may occur: 1) When the temperature is too low, the wettability of silicone structure sealant and the substrate surface is reduced, and there may be imperceptible fog or frost on the substrate surface, which affects the bonding between silicone structure sealant and the substrate. 2) Under low temperature and low humidity conditions, the curing speed and bonding speed of silicone structure sealant are slower than normal, which will lead to longer curing time and affect the construction. Winter construction problems： There are two kinds of architectural silicone structure sealant used in the construction of curtain wall engineering according to the composition classification: one is one-component silicone structure sealant, and the other is two-component silicone structure sealant. The curing mechanism and factors affecting the curing of the two types of silicone structure sealant are shown in the table below.   Winter construction countermeasure   In accordance with JGJ 102-2013 "Technical Specification for Glass Curtain Wall Engineering" section 9.1 regarding general processing, the injection conditions for silicone structural sealants must align with the specifications of the product. For instance, BAIYUN brand silicone structural sealant requires an environmental range of 10°C to 40°C with a relative humidity of 40% to 80% in a clean setting, and construction is not recommended during rain or snow. It's important to note that different manufacturers may have varying environmental requirements.   During winter construction, it is advisable to implement heating measures to ensure the construction temperature remains above 10°C. If there are specific circumstances requiring construction in lower temperatures (slightly below 10°C), conducting a small-scale adhesive test before use is recommended. Perform peel adhesion tests to confirm proper curing and bonding, and, if necessary, consider extending the curing time. When needed, the use of xylene for cleaning and applying primer coatings can be considered to expedite bonding and mitigate the risk of poor adhesion due to low environmental temperatures.     1) Before construction, conduct adhesive tests in advance and strictly follow the recommended methods from the adhesive tests.                                                                                                        ▲ Comparison of poor (left) and good (right) adhesion in aluminum bonding for a certain project. 2) The materials used during construction (aluminum, glass, sealant, cleaning agents, primer, etc.) come from various batches. Be aware that differences may exist between batches, and it's essential to conduct on-site adhesive tests randomly for each batch entering the site during the production process. ▲ Comparison of poor (left) and good (right) adhesion in on-site adhesive tests.   3) During construction, cleaning or primer application methods should align with the construction process. Strictly follow the "secondary cloth method" for cleaning, apply the primer promptly after solvent evaporation, ensuring a thin and even coat. Pay attention to the transition to the next step, and it's advisable to perform adhesive construction within half an hour after applying the primer. ▲ Uneven primer application causing localized non-adherence in a particular case. ▲ Uneven primer application causing non-adherence in sheet-like patterns in a specific case.   4) During the injection process, ensure the thorough mixing of components A and B within the manufacturer's recommended mixing ratio range. Confirm through butterfly tests and tensile tests. When changing containers, ensure proper ventilation. Inadequate ventilation may result in "bubble glue" – silicone structural sealant with numerous dense bubbles. Bubble glue has poor adhesion to substrates (aluminum, glass, etc.), leading to separation when pulled by hand, leaving black marks on the substrate. ▲ Poor adhesion to glass due to bubble glue in a specific case. ▲ Poor adhesion to aluminum due to bubble glue in a specific case. 5) After completing the on-site panel fabrication, move the panels horizontally to the curing area for proper curing. During the moving process, avoid misalignment between the aluminum frame and glass, as it can impact the bonding quality of silicone structural sealant.   Maintenance environment and maintenance time should ensure that the unit rubber cutting qualified.   After the completion of silicone structural sealant injection, the curing process should take place in a clean and well-ventilated environment with temperatures maintained between 10-40°C and humidity between 50-90%. When curing in a low-temperature and low-humidity environment, it may be necessary to extend the curing time appropriately. This is particularly evident in single-component silicone structural sealants, where the curing process is notably influenced by the duration of curing. In the same environment, a longer curing time results in a higher degree of solidification. ▲ Under low-temperature curing conditions, the curing time for a 10mm deep injection of single-component structural sealant increases from 10 days to 15 days, with an extended curing time.   If necessary, measures can be taken to raise the ambient temperature and humidity. The final determination of the curing time for finished units should rely on the tape cutting test, ensuring that the components are fully cured. Only after passing the tape cutting test (as shown in the image) can installation and handling proceed.                                                                                                           Cutting test.

220+standards, witnessing the road to becoming an industry leader    As a leading company in the domestic silicone sealant industry, BAIYUN has been committed to the promotion of industry standardization. So far, BAIYUN has participated in the drafting and revision of more than 220 international, national and industry standards, including more than 80 national standards, covering all fields of the sealant industry, and constantly promoting industry upgrading and reshuffle. In addition, BAIYUN has led the compilation and participated in the formulation and revision of more than 10 ISO international standards, making continuous efforts for China's sealant industry and China's sealant standards to go abroad, deeply participate in international competition, and strive for the right to speak internationally. Today, let us walk into BAIYUN together and witness the road to becoming a standard leader! NO.1 Lay the foundation for industry standardization    Standards are an important means to promote industrial upgrading, and the first standard is the beginning of industry standardization, which has extraordinary significance. The standardization of China's silicone sealant industry began in 1994. Before 1994, there was no unified standard for the identification of silicone sealants in the industry, and the market could not correctly select and use silicone sealants for construction, and the quality of sealant products on the market was uneven, resulting in confusion in the use of sealant in the construction industry. Huge hidden dangers have been buried for building safety, and the market urgently needs the emergence of standards for the safety performance inspection and appraisal of silicone sealants.    In this context, in 1993, proposed by the State Bureau of Building Materials Industry, Henan Building Materials Research and Design Institute, Chengdu Organosilicon Application Research Center of the Ministry of Chemical Industry, and Guangzhou State-owned Baiyun Viscose Factory (predecessor of Baiyun Chemical) actively responded to the call of the state and were responsible for domestic The first national standard for silicone sealants for construction was drafted.    In 1994, with the assistance of all parties, the first domestic national standard GB/T14683-1993 "Silicon Construction Sealant" for construction silicone sealants was officially implemented, which put forward mandatory standardization requirements for the mixed sealant market at that time. At the same time, it also laid the foundation for a series of subsequent standards. NO.2 Lead the world development trend    After the release of the first standard, the industry was able to get rid of the chaotic start-up state, quickly entered a new stage of development, and began to seek two-way improvement of technical strength and innovation ability on this basis. At the same time, my country is also continuously issuing and implementing new national and industry standards for silicone sealant series, leading the industry to make continuous progress. During this period, as the drafter of the first standard, BAIYUN actively invested various human and material resources to participate in the formulation and revision of industry standards, and gradually became a benchmark enterprise for domestic industry standardization. Highest - enterprise standard    BAIYUN has formulated enterprise standards for products that are 1.5 times higher than the national standard, among which the ultra-high performance structural sealant standard is the world leader, and some indicators have been significantly improved compared with European standards and American standards, and are more adaptable to extreme environments. Also more durable. This standard is by far the highest standard for structural sealants in the world. Highest -- group standard    Participated in and drafted the world's most advanced silicone structural sealant group standard - "High Performance Silicone Structural Sealant for Building Curtain Wall". This standard comprehensively improves the tensile adhesion and shear properties of structural sealants, and at the same time increases the testing items of alkane plasticizers, and has stricter requirements on thermal weight loss. Plastics, to eliminate "oil-extended plastic" safety hazards. In addition, the standard has more stringent requirements for low temperature test conditions, which broadens the scope of application of structural sealant products. Generally speaking, building silicone structural sealant products that meet the requirements of this standard will have a longer service life and further improve the safety index of curtain walls. The highest corporate standard, the highest group standard... BAIYUN has been advancing on the road of industry standardization, taking the first step in developing the industry and leading the industry in the next step. So far, China's silicone sealant standard system has become one of the three major silicone sealant standard systems in China, the United States and Europe. China has also become the world's largest sealant producer, consumer and exporter, and occupies a pivotal position in the international market. status.    As Chinese products are exported overseas, Chinese companies have gradually gained a firm foothold on the international stage and have more initiative in standard formulation.    As a vanguard of standardization, BAIYUN is also actively participating in the formulation of international standards: In 2018, BAIYUN hosted the 43rd ISO/TC59/SC8 (Guangzhou, 2018) International Standardization Annual Conference, representing China as an authoritative voice on the world standardization stage, At the same time, it also became the only Chinese sealant company that co-organized the conference. Since then, BAIYUN has gone further and further on the road of internationalization, not only sending experts to attend the ISO/TC59/SC8 annual meeting every year, but also sending experts to participate in the work of several working groups (WG). At present, including the leading ISO 13638:2021, BAIYUN has participated in the formulation, revision and successful release of 10 ISO international standards.    BAIYUN's continuous participation in international sealant standards and organizational work, representing China's voice on the stage of sealant international standards, has promoted the combination of my country's sealant standards and international standards, and contributed to the internationalization of Chinese standards, Chinese sealant brands going abroad, Going out to the world has laid a solid foundation.

How to apply silicone sealant under high temperature? Under high temperature, how can the sealant be properly applied to play its powerful role? This time, let's explore together—— 01 Summer construction, you need to pay attention to these! The environmental temperature requirements for the use of Baiyun brand silicone sealant products are: a clean environment with a temperature of 4°C to 40°C and a relative humidity of 40% to 80%. In an environment other than the above temperature requirements, it is not recommended for users to apply sealant. In addition, the outdoor temperature is higher in summer, especially the aluminum curtain wall, the temperature is higher. If the ambient temperature and humidity are not within the recommended range, it is recommended to conduct a small-area sealant test on site and perform a peel-off adhesion test to confirm that the adhesion is good and there are no defects before using it on a large area. 02 Under high temperature, it should be constructed like this!   Construction sequence of structural sealant (structural sealant for curtain wall, secondary structural sealant for hollow, etc.): 1) Clean the substrate In summer, the temperature is high, and the cleaning solvent is volatile, so attention should be paid to the impact on the cleaning effect. 2) Primer In summer, the temperature and humidity are high, and the primer is easily hydrolyzed and loses its activity in the air. Attention should be paid to injecting sealant as soon as possible after the primer is applied. At the same time, it should be noted that when using the primer, the number and time of the primer contacting the air should be reduced as much as possible, and it is best to use small turnover bottles for separate packaging. 3) Sealant injection After the sealant is injected, the weather-resistant sealant cannot be applied on the outside immediately, otherwise, the curing speed of the structural sealant will be seriously reduced. 4) trimming Trimming should be carried out immediately after the sealant injection is completed, which is conducive to the contact between the sealant and the side of the interface. 5) Record and identification After the above process is completed, it shall be recorded and marked in time. 6) Conservation Unit elements must be cured under static and unstressed conditions for sufficient time to allow the structural sealant to develop adequate adhesion. The construction sequence of weather-resistant sealant and door and window sealant: 1) Sealant seam preparation The foam stick on the sealant interface should remain intact. In summer, the temperature is high, and if the foam rod is damaged, it will easily lead to foaming; at the same time, attention should be paid to the compatibility of the substrate and the sealant. 2) Clean the substrate The sealant seam should be cleaned in place to remove dust, oil, etc. 3) Primer (if necessary) First of all, make sure that the surface of the sealant joint substrate is completely dry. In summer, the temperature and humidity are high, and the primer is easily hydrolyzed and loses its activity in the air. Attention should be paid to injecting sealant as soon as possible after the primer is applied. At the same time, it should be noted that when using the primer, the number and time of the primer contacting the air should be reduced as much as possible, and it is best to use small turnover bottles for separate packaging. 4) Sealant injection There are many thunderstorms in summer, pay attention to the fact that after the rain, the sealant seam should be completely dry before injecting sealant. 5) trimming In summer, the temperature is higher, and the trimming time is shorter than other seasons, and trimming should be done immediately after the sealant injection is completed. 6) Conservation In the initial stage of maintenance, it is not suitable to have a large displacement. 03 Frequently Asked Questions, Explained Once!   Short breaking time of structural sealant Judgment: The breaking time is shorter than the lower limit of the breaking time interval recommended by the manufacturer. Reason: The temperature and humidity are high in summer, and the breaking time is shortened. Solution: Adjust the ratio of components A and B within the range recommended by the manufacturer.     Structural sealant primer fails Reason: The temperature and humidity are high in summer, and the primer solution is easily lost if it is not used properly. Failure of the primer solution will lead to poor bonding of the structural sealant. Solution: The primer is best used in small bottles, and the unused primer solution in the bottle is not recommended to be used overnight; at the same time, it should be noted that when taking the primer, minimize the number and time of the primer contacting the air ; and check the state of the primer in the bottle in time. If the appearance has changed due to the prolonged storage time, the primer in the bottle is no longer used. Weatherproof sealant / door and window sealant blistering Judgment method: There are local protrusions on the surface of the silicone sealant. Cut the cured strip and the inside is hollow. Reason ①: The surface of the foam rod is punctured during the filling process, and the air is released from the hole after being squeezed; Solution: Keep the side of the foam rod in contact with the sealant intact. If it is not easy to fill, you can cut a part of the back of the foam rod. Reason ②: Some substrates react with the sealant; Solution: Pay attention to the compatibility of different types of sealants and substrates, and a compatibility test is required. Reason ③: Bubble phenomenon caused by thermal expansion of gas in the sealed sealant joint; The specific reason may be that in the entire closed sealant seam, the air sealed in the sealant seam after sealant injection expands in volume when the temperature is high (generally higher than 15°C), causing blisters on the surface of the uncured sealant . Solution: Avoid complete sealing as much as possible, and leave a small air outlet if necessary, and fill it up after the sealant is cured. Reason ④: The interface or accessory materials are wet; Solution: Do not construct on rainy days, and construct when the weather is fine and the sealant joints are dry. Reason ⑤: construction under outdoor high temperature conditions; Solution: Suspend construction in outdoor high temperature conditions, and start construction after the temperature drops. Weatherproof sealant / door and window sealant with short dressing time Reason: The temperature and humidity are high in summer, and the breaking time is shortened. Solution: Repair in time after sealant injection.
