Disadvantages Of Tempered Glass

1. The tempered glass can no longer be cut and processed. The glass can only be processed to the required shape before tempering, and then tempered.
2. Although tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-rupture), while ordinary glass does not have the possibility of self-explosion.
3. The surface of the tempered glass will have unevenness (wind spots), and there will be 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 increases, so the glass is thinner after tempering than before tempering. Generally, 4~6mm glass becomes thinner by 0.2~0.8mm after tempering, and 8~20mm glass becomes thinner by 0.9~1.8mm after tempering. The specific degree depends on the equipment, which is why tempered glass cannot be used as a mirror.
4. The flat glass used in buildings after passing through the tempering furnace (physical tempering) will generally be deformed, and the degree of deformation is determined by the equipment and technical personnel. To a certain extent, it affects the decorative effect (except for special needs).
