The Disadvantage Of Tempered Glass

- Feb 05, 2018 -


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


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


3 tempered glass surface there will be uneven (wind spots), a slight thickness thinning. The reason for the thinning is that because the glass softens in the hot melt and then rapidly cools by the strong wind force, the internal crystal gap in the glass becomes smaller and the pressure becomes larger. Therefore, the glass is thinner after being tempered than it is before being tempered. Under normal circumstances 4 ~ 6mm glass after thinning 0.2 ~ 0.8mm, 8 ~ 20mm glass after thinning 0.9 ~ 1.8mm. The specific level depends on the equipment to decide, which is why tempered glass can not be made mirror.


4. Through the tempering furnace (physical tempered) after the construction of flat glass, generally have deformation, the degree of deformation by the equipment and technical personnel process decision. To a certain extent, affect the decorative effect (except for special needs).
