Laminated glass is a safety glass made of two or more pieces of glass bonded together with synthetic resin. Laminated glass of the original film can be ordinary glass, it can be toughened glass, coated glass, heat-absorbing glass, bending glass, etc .; the middle layer of organic materials is the most commonly used PVB (polyvinyl butyral), but also methyl Methyl acrylate, silicone, polyurethane and the like. When the outer glass is subjected to impact rupture, the pieces are glued to live, forming only radial cracks, will not cause casualties caused by debris flying casualties. Laminated glass production methods are two: the film method (dry method) and grouting method (wet method), but the current dry-type production is the mainstream, glass washing machine is the best equipment for cleaning this type of glass.
Antenna glass is in the glass to increase the shape of the conductor, and then sandwiched between two pieces of glass, can play the role of receiving antenna. Antenna sandwiched in glass is less corrosive, accepts all band radio waves, and eliminates wind noise from the rod antenna. PVB film laminated glass refers to the laminated glass made of PVB interlayer film between two or more pieces of glass. The main component of PVB film is polyvinyl butyral, which is a condensation product of polyvinyl alcohol and butyraldehyde. PVB interlayer film can reduce the amount of noise through the glass, reduce noise decibels, to achieve sound insulation, the use of laminated glass made of PVB plastic interlayer can effectively block the common noise of 1000 ~ 2000Hz.
