[China Glass Net] The hollow glass industry is developing rapidly, but due to the lack of domestic hollow glass basic theory, this paper introduces several methods to easily distinguish the advantages and disadvantages of insulating glass for reference. Any piece of insulating glass is taken from the finished product, and any of the following phenomena can be found. The consumer can judge that it is a non-conforming product and requires a return. 1. Cut the two seals into one section with a knife. If there are many small pores (small honeycombs) in the cross section, this means two possibilities. One is to manually glue the glue, it will be wrapped in the air, and the bubbles will be generated. Another possibility is to use The two-way sealant produced by the low-level technology will also have pores when the machine is glued. As long as the pores appear in the cross section, the life is definitely short. 2. Use a knife to cut open at any corner of the insulating glass to see if the joint angle is effectively wrapped with butyl rubber. The actual theory shows. The double-pass sealed insulating glass made by the joint angle method has a water-permeable path mainly at four corners, and the water permeability is 70%, and the water permeability of the edge is 30%. Therefore, the use of continuous curved aluminum strips or butyl rubber to effectively wrap the four joint angles can greatly extend the service life of the insulating glass. If the four corners are not effectively wrapped with butyl rubber, the double seal The practical significance is not great. 3. Use a knife to cut the two sections of the two seals and the glass by a few centimeters, and then tear the sealant out by hand. If the surface of the glass is smooth after tearing, there is no residual glue, indicating that the sealant and the glass surface have no adhesive force, so the sealing effect can be imagined. 4. Add the above methods to check whether the standard molecular sieve is used, whether the butyl rubber is continuous (no broken wire), if it is not polysulfide rubber, whether the other two sealants have been tested for compatibility (must be compatible) Experiment, otherwise it is very likely that the problem will be infinite.) If the window frame seal is not a standard rubber strip seal, but is sealed with ordinary silicone rubber, it is necessary to use the silicone rubber and the insulating glass edge sealant for compatibility experiments. Otherwise, it may endanger (some windows and doors are installed). The company purchased the inferior oil-filled silicone rubber to seal the window frame. Over time, the mineral oil migrated out to erode the entire insulating glass sealing system. Since it takes a while for this evil to manifest itself, it must be prevented in advance. Insulating glass quality control approach Although the basic theory of insulating glass in domestic systems is not perfect, in recent years, the rapid development of domestic insulating glass, various types of insulating glass production equipment have been widely used in production practice. At the same time, in the history of the development of insulating glass in the past 20 years, we have accumulated many practical experiences in both positive and negative aspects. The author now summarizes the following quality control approaches as follows. Nantong NATASHA Textiles Co.,Ltd. , https://www.ntnatashatextile.com
