[China Glass Network] In recent years, the country has become more and more demanding on building safety. The use of building safety glass is also becoming wider and wider. Tempered laminated glass is still a safer type of safety glass. No safety glass can compare with it. It is widely used in cars, trains, buildings, etc. Derivative products of tempered laminated glass, bulletproof glass is widely used in financial institutions, and has made great contributions to the safety of the business industry.
1. Dry tempered laminated glass
Dry tempered interlayer, some use float glass, some use tempered glass glued tempered laminated glass, float tempered laminated glass original film is relatively flat, high production yield, in addition to damage, generally no bubbles, glue Layer whitish and other issues. However, the strength of the general tempered laminated glass is relatively low, and the damage during the safety construction is relatively high. Many decorative companies have adopted tempered tempered laminated glass to solve the problem of damage during installation. The strength of this kind of glass is improved, but the deformation of the tempered glass in the quenching of the glass brings unimaginable difficulty in producing the tempered laminated glass. Many companies have begun to thicken the PVB film to solve the unevenness of the tempered glass. However, during the processing of the kettle, the temperature of the glass is relatively fast, the thermal conductivity of the glass is different from the thermal conductivity of PVB, and the edge of the glass is firstly combined with PVB. The films are bonded together, making it difficult to discharge the gas in the middle of the tempered laminated glass, resulting in a large amount of waste and being difficult to use. In this case, you can choose to use chemical spraying to solve it.
Second, dry hot bending tempered laminated glass
The dry hot-bending tempered laminated glass is mainly used for the front windshield of automobiles. The previous production process is complicated and the cost is too high. The preheating and pre-pressing process is indispensable. The use of silicone strips, preheating and vacuuming are very troublesome, and the finished products are finished. The rate is not high. Fixing the film and glass directly into the autoclave saves labor and reduces costs, and the yield is also improved.
Third, wet tempered laminated glass
When solving the wet tempered interlayer bubbles, the thermal polymerization product has stable quality and high strength, and there is no difference between the dry tempered interlayer and the photopolymerized glass.
