Brief analysis of different methods for removing bubbles in tempered laminated glass

in recent years, the national requirements for building safety have become higher and higher. The use of building safety glass is also more and more extensive. Tempered laminated glass is still the best kind of safety glass in the category of safety glass, and no safety glass can be compared with it. It is widely used in cars, trains, buildings and so on. Bulletproof glass, a derivative of tempered laminated glass, is widely used in financial institutions, making a great contribution to the safety of the business industry

I. dry toughened laminated glass

dry toughened laminated glass, some of which are made of float glass, and some of which are made of toughened glass. It has a high mobility of toughened laminated glass. The original piece of float toughened laminated glass is relatively flat, and the production yield is high. Except for damage, there are generally no bubbles, and the bonding layer is white. However, generally, the strength of tempered laminated glass is relatively low, and the damage in safe construction is relatively high. Many decoration companies in Jier have widely adopted tempered laminated glass, which solves the problem of damage in installation. The strength of this kind of glass is improved, but due to the deformation of tempered glass during glass quenching, taking another sample for rework brings unimaginable difficulties to the production of tempered laminated glass. Many enterprises began to thicken the PVB film to solve the unevenness of tempered glass, but in the processing process of entering the kettle, due to the continuous improvement of the industrial batch production management system, the glass edge temperature rises faster, and the thermal conductivity of glass is different from that of PVB. The glass edge is first bonded with the PVB film, making it difficult to discharge the gas in the middle of tempered laminated glass, resulting in a large number of waste products, which are difficult to use. In this case, you can choose to solve it by chemical spraying

II. Dry hot bending toughened laminated glass

dry hot bending toughened laminated glass is mainly used in the front windscreen of cars. In the past, the production process was complex and the cost was too high. The process of preheating and preloading must be indispensable. It is very troublesome to use silicone strips, preheating and vacuum pumping, and the yield is not high. Fix the film and glass well and send them directly to the autoclave, which saves labor, reduces the cost and improves the yield

III. wet toughened laminated glass

when solving the bubble of wet toughened laminated glass, the quality of thermal polymerization products is stable, and the strength of high-speed railway testing instrument company is high, which is no different from that of dry toughened laminated glass, while the quality of photopolymerized glass is unstable
