Type 1 automotive glass
First, a laminated glass
Characteristics of the laminated glass:
1, high impact strength, by the impact after brittle broken glass, but because it is flexible and combined PVB, laminated glass having a high penetration resistance, can maintain visibility.
2, high bond strength, high glass and PVB adhesion, when broken glass, glass fragments remained adhered to the PVB no peeling, no hurt, with security.
3, light, heat, humidity, cold.
The rupture laminated glass may shatter under heavy ball striking, but still maintain the integrity of the glass block, sharp fragments and small pieces still stuck together with the intermediate film. When this broken glass fragments should not dispersed, the use in automobiles and other vehicles.
Second, the tempered glass
glass characteristics:
1, high strength, impact strength of glass of the same thickness of ordinary glass 3 to 5 times, bending strength was three to five times that of ordinary glass.
2, thermal stability, glass having good thermal stability, can withstand the temperature difference is 3 times that of ordinary glass can withstand the temperature change 200 ℃.
3, safety glass is broken when an external force debris into a honeycomb-like particles Suixiao obtuse, not harm the human body.
Once broken, the entire burst into numerous fine glass particles, cullet little remaining frame.
Since the glass require a large striking force was broken, the fragments of small particles and a uniform shape without sharp corners universal glass cutter so as to be referred to is widely used in automotive safety glass, in interior , high windows and open floor outside.
Third, the tempered glass with laminated glass Comparison
Laminated glass is used in a transparent plastic film may be attached to the adhesive between the two or three layers of glass, a hard glass binding toughness and plastic together, increasing the glass anti-crushing capacity. Tempered glass is ordinary glass quenching refers to the internal stress of a certain tissue, such that the enhanced strength of the glass, when broken by the impact, the glass will be split into small pieces with a blunt edge, and not harm the occupant. The glass area is a new breed of tempered glass, which is specially treated, can break upon impact, which can crack the glass still maintain a certain clarity to ensure that the driver’s field of vision area is not affected.
