The production of automotive glass is to heat the glass to a temperature close to the softening temperature in a heating furnace, and then quickly send the glass into the air grids with different cooling intensities to cool the glass unevenly, so that the main viewing area of the glass is different from the surrounding area. Stress, generally this produced glass is area tempered glass.
The surrounding area is in the strong wind position of the wind grid, so it needs to be fully tempered. The degree of debris in this position is good and the tempering strength is high. The main viewing area is in the weak and cold position of the wind grid, with large debris and low tempering strength.
Automobile glass is an indispensable part of automobile body accessories, and it mainly plays a protective role. There are three main types of automotive glass: laminated glass, tempered glass and regional tempered glass, which can withstand strong impact. Automotive glass is divided into four types according to the location: front windshield, side window glass, rear windshield and sunroof glass;
The front windshield is mandatory by the state and must be laminated glass (some low-cost agricultural vehicle front shields are still tempered glass or regional tempered glass) The side window glass is tempered glass, and the rear windshield is generally tempered glass with electric heating wires
