Sealant selection of glue beater is good, which has a good effect on product quality. The following two-component glue beater manufacturers will introduce several common types of sealant to you!
1. Butyl gum:
Butyl glue is the first seal of aluminium strip type hollow glass. It is a kind of hot melting glue with low water vapor permeability (very low in hollow glass glue) and high viscosity. It is a very effective barrier to water vapor between aluminium strip side and glass, but it needs to be heated, pressurized and extruded by special machine and coated on both sides of aluminium strip.
At present, there are many domestic butyl rubber manufacturers, but the heating temperatures and pressures of the glues produced by each manufacturer are different. Some manufacturers'butyl rubber can not even be coated by machine, which often results in interruption due to impurities. This requires users to choose products of good quality and understand their requirements.
2. polysulfide gum:
Polysulfide is one of the most widely used hollow glass sealants at present. polysulfide has good oil resistance, solubility and sealability. Polysulfur adhesives should be polymerized with metal oxides as curing agent. The ratio of the two components is about 1:10. The proportion and uniformity of the two components have little effect on the effect. Therefore, the adhesives can be coated by machine or by hand.
Requirements for selection of polysulfide adhesives: clear color difference between two components; validity period of more than half a year; strong anti-ultraviolet ability; good fluidity and curing elasticity.
3. Silicon Tunnel Glue
Silicon tunnel sealant has structure, aging resistance and ultraviolet resistance, but its weakness is high water vapor permeability. Therefore, silica tunnel gel is suitable for places with strong illumination and poor environment, such as glass curtain wall. At the same time, butyl rubber must be used to make a seal. In the past, China relied on imports for a long time. Now the State Economic and Trade Commission has set up a leading group of silica gel to certify the safety of structural gel. At present, many enterprises in China have passed the certification.
