Basic knowledge of Automobile Float Glass

Automobile sheet glass is made by heating the flat glass in a reheating furnace to near the softening temperature, and then rapidly sending the flat glass into a wind grid of different cooling strength, which is not evenly cooled, resulting in different stresses in the main view area and the peripheral area of the flat glass. Generally speaking, this kind of flat glass is made of regional tempered glass.

Because the surrounding area is in the strong wind position of the wind grid, so it needs to be fully tempered. The debris degree in this position is good, the strength of the steel is high, the main view area is in the weak cold position of the wind grid, the debris is large, and the toughening intensity is low.

Conception

Automotive sheet glass is indispensable in the automobile body accessories, mainly play a protective role. Automotive sheet glass mainly three types: laminated glass, toughened glass and regional tempered glass, because they can withstand strong impact. Automobile sheet glass is divided into four kinds according to the position: front windshield glass, side window glass, rear windshield glass and skylight glass.

The front windshield glass must ba made of laminated glass, the side window is made of tempered glass and the rear windshield glass is made of toughened glass with charged heating wire.

Development

The data shows that the global auto sheet glass industry is divided according to the theme of the consumer market. Europe, North America, Japan, China and South Korea account for 34 percent and 5 percent respectively, accounting for 933 percent of the global auto glass market. The global auto sheet glass market is highly monopolized by enterprises, and Japan's Asahi Glass Company is the world's largest float glass manufacturer, accounting for almost 25% of the auto sheet glass market, and the glass giant also occupied the automobile sheet glass market huge share. Three largest automobile sheet glass manufacturers in the world AGC) and Saint-Gobain, together with their joint ventures around the world, account for about 70 percent of the global OEM market.

With the rapid development of China's auto industry, the demand of China's auto sheet glass industry has increased by 20 percent each year. Fuyao Group is the largest auto sheet glass manufacturer in China, accounting for 10 percent of the world's auto sheet glass market, and has a high share of 60 percent in the domestic OEM market.
