In comsequence, the impact applied to the glass will be overcome by the compressional force on the surfaces to assure safety of use.tempered glass is high strengh,It is 4-5 times higher than normal glass and also shockproof tempered glass is high strengh.Its compressive strength could be more than 125MPA, It is 4-5 times higher than normal glass and also shockproof. It is unwounded when a steel ball that is 0.8kg fall dowm from 1.2m high. tempered glass is also the secondary processing production of flat glass. The processing of tempered glass can not be divided into physical methods and chemical methods. tempered glass is proceed a compression stress on the surface of glass use of the method of chemistry or physics.It makes the glass have higher compression strength and hard to be damaged. When glass offered the external stress, the compression stress bears offset part of tension glass, to avoid the broken of glass.Although the inside of tempered glass is at tension stress, it is flawless, and wont be damaged so as to improve the strength of glass.
