50-year limit test 5th anniversary results summary
All existing artificial accelerated aging methods cannot repeat the aging of the structural adhesive during the application of the actual curtain wall. Therefore, it is of great significance to carry out the natural exposure test of the structural adhesive.
Baiyue Chemicals extended the natural rubber exposure test of structural rubber to two test sites with international benchmarks in the United States. It can not only obtain data on the durability of structural adhesives comparable to other international brands, but also is a strategy for building international sealant leaders. The move has very important significance for the approval of international customers for its products.
At the seminar, Vice President Yang Yuong, together with the 50-year limit test five-year test data, the keynote speakers' theme report and expert discussions, gave a detailed summary of the meeting:
(1) The durability of silicone materials is the best among polymer materials;
(2) From the results of the continuous monitoring experiment after the 5th anniversary of exposure to different branded products of the sample, see:
The quality of domestic sealant products varies greatly. Under the extreme exposure, with the passage of time, many sealant products conforming to the current regulatory standards have also experienced varying degrees of problems, creating a number of safety hazards for building curtain walls.
Throughout the five-year exposure test data, only high quality, good performance silicone sealants can achieve excellent aging resistance.
Practice is the sole criterion for testing truth. Therefore, the formulation of standards in the industry should also advance with the times and be updated dynamically.
(3) Baiyin Chemical's series of products are trustworthy through the test results of the sealant products exposed by Baiyun Chemical's 20-year exposure to the wall and test pieces placed on the scenes of two major explosions in Guangzhou and Turpan.
Vice President Yang Yuong also sincerely hopes that Baiyun Chemical, as a leader in the industry, can give more play to the social responsibility of leading companies, continue to carry out technological innovation, and continue to contribute to the healthy development of the industry.
"Research into textbooks"
- Experts highly praised the 50-year limit test
During the discussion session, the experts highly evaluated the 50-year limit test and provided many opinions and suggestions on the improvement and improvement of the test.
At the same time, experts in materials and curtain wall areas have also conducted in-depth exchanges and raised more expectations for the future development of building polymer materials.
The building is getting higher and higher, the cost of curtain wall maintenance is getting higher and higher; the popularity of prefabricated buildings, the integration of indoor and outdoor use years; the trend of the industry, etc. all make the durability of materials increasingly prominent, and hope that the industry will achieve more outstanding results. Can be applied to the construction field.
The result of 20 years of exposure to a solid curtain wall has given me a lot of inspiration. It shows that the product is guaranteed and rest assured!
The 50-year limit test, I witnessed in Turpan 5 years ago. In the past 5 years, there has been no change in product performance. Rest assured!
10 years ago, I participated in the Guangzhou West Tower using white glue, 10 years later is still intact, rest assured! This also provided us with full confidence in our follow-up to the 1007-meter Saudi Kings Tower!
At the basic research level, the 50-year limit test is a textbook study;
From a practical point of view, it is the true embodiment of the spirit of artisans;
At the same time, Turfan and Guangzhou, as the explosion fields, are the two starting points of the ancient Silk Road and the Maritime Silk Road, respectively, and coincide with the national “One Belt and One Road”!
The service life of the building is 50 years. How many years can the sealant be used? From the material point of view, this test is particularly important.
It is hoped that the test will be combined with practical applications to add more indicators of the impact of adverse urban environments (such as acid rain) on sealants.
Twenty years of actual application data have been tracked, and we must make good use of it; at the same time, we combine natural exposure data and artificially accelerated aging data to further judge the actual application age.
The experiment can further focus on typical climate regions in the east, west, south, and north, and is more instructive.
How many years can structural sealant be used? This is a "world proposition." It is difficult, but it needs someone to do it.
As a curtain wall consultant, we often say to the owner: 100% believe that white clouds glue, 100% believe that the domestic big brand products!
At one time, we were more concerned about the use of the sealant, the use of the size, and contempt for performance. Nowadays, Zhejiang will usher in the safety screening of existing curtain walls. How to determine the problem of structural sealant failure is before us. This requires data support in the field of materials.
Baiyun Chemical has a large market share in Zhejiang, and is also a participating unit in the safety identification of curtain walls in Zhejiang. The association hopes to join hands with leading companies represented by Baiyun Chemical to make more contributions to the safety industry.
Baiyun Chemical is amazing and is willing to use 50 years to solve the reliability problem of polymer materials!
After 5 years of hard work, the 50-year limit test of sealant has become the organic combination of scientific exploration and enterprise creation, and collaboration between cross-border experts and cross-country experiments! This seminar will become a milestone on the long road of 50-year limit testing, providing more direction for this long-term research, and pointing out a broader space for the development of theoretical data on how to better serve practical applications.
