Disadvantages Of Tempered Glass

Disadvantages of tempered glass:
1. After tempering, the glass cannot be cut or processed. It can only be processed to the required shape before tempering.
2. Although tempered glass is stronger than ordinary glass, it has the possibility of self-explosion (breaking by itself), while ordinary glass does not have the possibility of self-explosion.
3. The surface of tempered glass will be uneven (wind spots) and slightly thinner. The reason for the thinning is that after the glass is softened by hot melt, it is quickly cooled by strong wind, which makes the crystal gap inside the glass smaller and the pressure greater, 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 also the reason why tempered glass cannot be made into mirror.
4. Flat glass used in buildings will generally be deformed after passing through a tempering furnace (physical tempering). The degree of deformation is determined by the equipment and the craftsmanship of the technicians. To a certain extent, it affects the decorative effect (except for special needs).
