About Tempered Glass

Tempered Glass is a glass with compressive stress on the surface. Also known as strengthened glass. The tempering method was used to strengthen the glass, which began in France in 1874. When the glass is damaged by external force, the fragments will become small particles with obtuse angles similar to honeycombs, which are not easy to cause serious harm to the human body. There are many advantages and disadvantages.

advantage

The first is that the strength is several times higher than that of ordinary glass, and it is resistant to bending. The second is safe use. The increased load-bearing capacity improves the fragile nature. Even if the toughened glass is damaged, it will be small fragments without sharp angles, which greatly reduces the damage to the human body. The quenching and heating resistance of toughened glass is 3 to 5 times higher than that of ordinary glass, and it can generally withstand temperature changes of more than 250 degrees, which has a significant effect on preventing thermal cracking. It is a kind of safety glass. To ensure the safety of qualified materials for high-rise buildings.

shortcoming

Disadvantages of tempered glass:

1. The toughened glass can no longer be cut and processed. The glass can only be processed to the required shape before toughening, and then toughened.

2. Although the strength of tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (breaking by itself), while ordinary glass does not have the possibility of self-explosion.

3. There will be unevenness (wind spots) on the surface of the tempered glass, and there will be a slight thickness thinning. The reason for the thinning is that after the glass is melted and softened, it is rapidly cooled by strong wind, so that the crystal gap inside the glass becomes smaller and the pressure becomes larger, So the glass is thinner after tempering than before. Generally, 4~6mm glass becomes 0.2~0.8mm thinner after tempering. And 8~20mm glass becomes 0.9~1.8mm thinner after tempering. The specific level depends on The equipment. which is why tempered glass cannot be used as a mirror.

4. The flat glass used in construction after passing through the tempering furnace (physical tempering) will generally be deformed, and the degree of deformation is determined by the equipment and the technology of the technicians. To a certain extent, it affects the decorative effect (except for special needs).
