Tempered Glass (tempered glass)

tempered glass is processed by heating standard float glass to a temperature of about 700 centidegree, then cooling it rapidly to form a compressive surface on the glass. Tempered glass can be divided into two categories: fully tempered glass and partially tempered glass (also called heat strengthened glass).tempered glass has roughly three to four times as much strength as the same thickness of ordinary glass. When the glass breaks due to external force, the glass shatters into grains like beans, which can lessen or prevent injuries to people. Tempered glass can stand rapid temperature changes(for example: 5mm thick tempered glass can stand 200 centidegree temperature change.)partially tempered glass has two to three times as mach resistance to vibration as the same thickness of ordinary glass, When the glass breaks due to external force, the cracks radiate from the impact point to the edge and most of the broken glass pieces remain in the frame. This can lesson or prevent injuries to people, the surface quality is better than tempered glass. This kind glass is used for windows and other parts of buildings, glass partitions and elevator partitions.
