At present, the glass on the car is mainly divided into two materials, laminated glass and tempered glass. Laminated glass is a two-layer glass with a plastic film between them that does not completely crack and diffuse in the event of damage and rupture.
Because of this characteristic, laminated glass is required to be used on the front windshield in order to ensure that the driver is given as complete implementation and safety as possible after the impact. After being damaged, tempered glass will quickly spread into countless small particles, and is prone to shedding phenomenon, in a critical moment can be easily escaped, and the car side and back by the probability of impact by the stone is less than the front windscreen, so tempered glass is widely used in addition to the front windscreen other parts.
Types of automobile glass
1. In a narrow sense, automotive glass is divided into laminated glass and toughened glass, which is made of glass after secondary processing. Generally, class a laminated glass is widely used in the front windshield of automobiles, while tempered glass is mostly used in other glasses, and sandwich and insulating glass are also used in some medium and high-end automobiles. 1) Laminated glass: laminated glass is a kind of processing glass formed by gluing two or more layers of glass. It is generally divided into flat laminated glass and curved laminated glass. At present, bending laminated glass is widely used in automobile, and a few window glass is flat laminated glass. 2) Tempered glass: tempered glass is a kind of glass product which is quenched and quenched when the glass is heated to the softening temperature. Because the surface compressive stress and internal tensile stress of toughened glass are consistent or basically balanced, toughened glass has strong impact resistance and good thermal stability. Toughened glass is generally divided into fully toughened glass and regional toughened glass. The former is applicable to the side windows, rear bumper and buildings of automobiles, while the latter is applicable to the front windshield of ordinary cars, large passenger cars, vans and trucks. It has high strength, but it is crushed.
2. Other types of automotive glass derived from laminated and tempered glass.
Insulating glass: sandwiched between two layers of tempered glass, it is a new product of heat insulation and sound insulation. If coated glass is used for insulating, the best effect of being warm in winter and cool in summer can be obtained. It can be used in the side windows of cars, all kinds of buildings, food cabinets, freezers and places where air conditioning and sound insulation are needed.
Bulletproof glass: a kind of glass with more than two layers of glass (or tempered glass) obtained by sandwich
Special glass with bullet proof function. Bulletproof glass is an extension of laminated glass,
It can be used in all kinds of transportation, financial institutions and buildings for storing valuables.
