Glass is an indispensable part of doors and windows. The early building windows and doors are single-layer flat glass, which has been developed into tempered glass, insulating glass, laminated glass and bullet-proof glass. Most of today's door and window products use tempered glass. However, after glass tempering, the surface mechanical strength of the glass is 3 to 5 times higher than that of ordinary glass, but the tempered glass corner is relatively fragile and may be broken after being subjected to an external force. In addition, if the outside temperature changes frequently, tempered glass may also self-explosion. Relevant persons are reminded that when using tempered glass products, they should be careful not to bump the corners. It is recommended that the temperature of the glass should not be changed drastically to avoid self-explosion.
1, with high impact strength
It is 4 to 5 times higher than ordinary glass; it has high bending strength and is 5 times higher than ordinary flat glass; it has good thermal stability and can withstand temperature difference of 200 °C; it is also characterized by smoothness, transparency and non-cutting. In the case of super strong impact damage, the fragments are scattered and fine particles, without sharp edges and corners, so it is also called safety glass.
2. The tempered glass will have a slight thickness thinning after tempering.
The reason for the thinning is that after the glass is melted by hot melt, it is rapidly cooled by a strong wind force, so that the internal crystal gap of the glass becomes small and the pressure becomes large, so the glass is thinner after tempering than before tempering. Under normal circumstances, 4-6MM glass is thinned 0.2-0.8MM after tempering, and 8-19MM glass is thinned by 0.9-1.8MM after tempering. The degree of specificity depends on the equipment.
