The process of tempered glass is to heat the original glass to a very high temperature and cool it down rapidly to form the surface compressive on the glass.According to the shape it can be divided into the fully tempered glass and the heat strengthened glass (also called semi-tempered glass). The tempered glass is 3-4 times as strong as the common glass.Broken by the external force, it will become the bean-sized scrap, so as to lessen or avoid the injury to human body. The tempered glass has the virtues of high degree of precision,low rate of self-blast and without stressing flaw. Product Specifications: Maximum size: 6000mm × 2440mmMinimum size: 200mm × 200mmThickness: 2 -25mm (tempered) , 2 -10mm (semi-tempered) Standards : CE(EN12150), AS/NZS 2208:1996. BS6206, ASTM1048-97, JISR3206-96, DIN18516, SGCC. Note : The tempered glass will sometimes self-blast due to the characteristics itself. The cause is about the NiS.which turns into instability after heating and sudden cooling. The possibility of self-destruction is low, yet it can't be wiped out.To minimize the chances of self-blast,we have large heat-soaked furnace to detonate the potential danger of the tempered glass.Once being heat-soaked,the self-destruction probability will be reduced from 1/1000 to 1/100,000.
