tempered glass

Detailed Product Description

Tempered glass is high strength. Its compressive strength could be more than 125MPa. it is also shockproof.

Tempered glass also called toughened glass. It is produced a compression stress on the surface of glass use the method of chemistry or physics. It makes the glass have higher compression strength and hard to be damage. When glass offered the external stress, the compression stress bears offset part of tension stress, to avoid the broken of glass. Although the inside of tempered glass is at tension stress, it is flawless, and wont be damage so as to improve the strength of glass.

Tempered glass is the secondary processing production of flat glass. The processing of tempered glass can be divided into physical methods and chemical methods.

Tempered glass is high strength. Its compressive strength could be more than 125MPa. It is 4-5 times higher than normal glass. The tempered glass is also shockproof.. It is unwounded when a steel ball that is 0.8kg fall down it from 1.2m high. 
The flexibility of tempered glass is much higher than normal glass. A piece of tempered glass which size is 1200mm*350mm*6mm can be 100mm bending deflection when it is stressed. After stress can restorable. But the general glass can be bending to several millimeters.
Tempered glass is good heat stability. There is another feature of tempered glass. That is not easy to explosive to scrap when heat shock. That is because the compression stress of tempered glass bears offset part of tension stress that is caused by heat shock. Tempered glass has high level heat shock resistance. The minimum safe work temperature is 288, it can work on the change of the difference temperature between 204.

Based on the high mechanical property and high heat stability, tempered glass is used widely in architecture engineering, vehicle and other fields. Flat tempered glass often used for the windows, doors, partition wall, curtain wall, show window and furniture. Bent glass always used for automobile, train, plane and so on.

Some points for attention in using are that the tempered glass cant be cut and grinding; the edge cant be knock and press. It must be select or propose the exact drawing to processing according to the ready specification. `The glass which is used in the large acreage glass curtain wall should be control when it is tempering. The stress of half tempered glass can t be too big to avoid the broken caused by shocked of wind loading
