Disadvantages of tempered glass:
1 The tempered glass can no longer be cut and processed, and the glass can only be processed to the required shape before tempering, and then tempered.
2 Although the strength of tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-breaking) when the temperature difference changes greatly, and ordinary glass does not have the possibility of self-explosion. The surface of the production process tempered glass will have unevenness and a slight thickness thinning. 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 8-20MM glass is thinned by 0.9-1.8MM after tempering. The degree of specificity depends on the equipment, which is why tempered glass cannot be mirrored.
