Not man-made destruction of tempered glass why suddenly broken
Tempered glass has bleed characteristics
This is because the glass raw materials containing nickel sulfide crystals, is the world's existing manufacturing technology can not be completely avoided, only through the purity of raw materials and processing technology to control the risk of a little lower blew.
On the concept of self-blasting rate, our country only on the external walls of the engineering glass has a national standard, I do not know whether the foreign industry for the use of tempered glass also has detailed provisions.
One ton of glass raw materials, there are at least 3-4 nickel sulfide crystals, this one ton of glass made of several square meters of the size of the glass, which will have 3-4 tablets blew, which is blew the image depicting.
