The reason why the glass should be tempered:
1. After the glass is tempered, its strength is several times higher than that of ordinary glass, its bending strength is 3 to 5 times that of ordinary glass, and its impact strength is 5 to 10 times that of ordinary glass, which improves the strength and safety at the same time. The quenching and heating resistance of toughened glass is 2 to 3 times higher than that of ordinary glass, and it can generally withstand temperature changes of more than 150LC, which has a significant effect on preventing thermal cracking.
2. It is safe to use, and the load-bearing capacity is increased to improve the fragile nature. Even if the toughened glass is damaged, there are small fragments without acute angles, which greatly reduces the damage to the human body after the accidental broken glass.
The method of tempered glass:
The ordinary glass is cut to the required size, and then heated to about 700 degrees close to the softening point of the glass, and then quickly and uniformly cooled (usually 5-6MM glass is heated at 700 degrees for about 240 seconds, and the temperature is cooled for 150 seconds. About), the glass is heated to a suitable temperature and then quickly cooled, causing the glass surface to shrink sharply and produce compressive stress. However, the middle layer of the glass cools slowly, and it is too late to shrink, so tensile stress is formed, which makes the glass obtain higher strength.
