Is one of safety glass. The safety of qualified materials is guaranteed for high-rise buildings. The disadvantages are as follows: the tempered glass can not be cut and processed any more, and the glass can only be processed to the required shape before tempering and then is tempered; although the strength of the toughened glass is stronger than that of the common glass, the toughened glass has the possibility of self-explosion (self-fracture), but the common glass does not have the possibility of self-explosion; the surface of the toughened glass has an uneven phenomenon (wind spots) and has a slight thickness reduction. The thinning reason is that after the glass is melted and softened, the glass is rapidly cooled by strong wind force, so that the crystal gap in the glass is reduced, the pressure is increased, and the glass is thinner after tempering than before tempering; the flat glass for buildings after passing through the toughening furnace (physical toughening) generally has deformation, and the deformation degree is determined by equipment and a technician process.
