Talking about toughened glass

characteristic

safety

When the glass is damaged by external force, the fragments will break into small particles like honeycomb obtuse angles, which is not easy to cause serious harm to the human body.

high strength

The impact strength of the same thickness of tempered glass is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.

Thermal stability

Tempered glass has good thermal stability, can withstand a temperature difference that is three times that of ordinary glass, and can withstand temperature changes of 300 ° C.

advantage

The first is that the strength is several times higher than ordinary glass, and it is resistant to bending.

The second is safety in use. Its increased load-bearing capacity improves fragile properties. Even if the tempered glass is broken, small fragments without acute angles are displayed, which greatly reduces the harm to human bodies. The tempered glass has a 3 to 5 times improvement in resistance to quenching and heating, and can generally withstand temperature changes of more than 250 degrees, which has a significant effect on preventing thermal explosion. It is a kind of safety glass. To ensure the safety of qualified materials for high-rise buildings.

Disadvantage

Disadvantages of Suzhou tempered glass :

1. The tempered glass can no longer be cut and processed. It can only be processed to the required shape before tempering, and then tempered.

2. Although the strength of tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-rupture), but ordinary glass does not have the possibility of self-explosion.

3. The surface of the tempered glass will have unevenness (wind spots), and it will be slightly thinner. The reason for the thinning is that after the glass is melted and melted, it is rapidly cooled by strong wind, which makes the crystal gap in the glass smaller and the pressure becomes larger. Therefore, the glass is thinner than before it is tempered. 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 degree depends on the equipment, which is why tempered glass cannot be used as a mirror.

4. After the tempering furnace (physical tempering), the flat glass used in construction will generally be deformed, and the degree of deformation is determined by the equipment and technicians' processes. To a certain extent, it affects the decoration effect (except for special needs).
