Safety glass 1
Introduction:
There are two types of safety glass: tempered glass with laminated glass. Tempered glass is a glass in the hot state so that the prestress generated by rapidly cooling the high-strength glass, no sharp edges disintegrated into small pieces of glass when broken, difficult to wounding. A total of 3 layers laminated glass, and have a strong interlayer adhesion and toughness, impact damage when the inner and outer layers are adhered to remain on the intermediate layer, is not easy to wounding. A laminated glass for automobiles, the intermediate layer is thicker than doubled, and better security and are widely used.

Common automotive glass are the following: tempered glass, tempered glass partially, laminated glass.
automotive safety glass is one of automotive passive safety equipment, automotive safety glass must meet the following factors: good vision, strong enough, when the accident occupant protection. Common automotive glass are the following: quenched and tempered glass, local tempered glass, laminated glass. Ordinary glass is tempered glass sheet from the heating and quenching, there its internal stress, internal stress of the glass which has a high resistance to physical shocks.
This 4 times higher resistance than ordinary glass. When subjected to a strong impact, will be broken into granular, it will not harm people. Further, because after heat treatment, the ability to enhance its resistance to temperature changes. With a 5-mm thick ordinary glass, the temperature variation is greater than 70 degrees Celsius will break. And a tempered glass can withstand a temperature change of about 170 degrees Celsius.
partially tempered glass is transferred to a qualitative glass, and tempered glass as solid. Originally developed to manufacture automobile windshield, and when it burst, become fragmented special shapes and sizes, in order to ensure the safety of the driver.
is glued laminated glass formed by two glass common intermediateSandwiching a layer of film, the glue repression. When rupturable membrane may be sandwiched prevent rocks or other objects Feizhi penetrate to the other side, broken glass can also prevent splashing. Laminated glass ensures minimum visibility required for the driving.
In addition to the three or more types of glass having other special functions as well as automotive glass: hot imprint glass, colored glass. Their common characteristic is transparency or have reached more than 70 percentage.
