Sandwich laminated glass rupture, in heavy ball impact may be broken, but one glass remained, fragments and sharp and small debris still stick together with the middle membrane. This glass is broken, fragment not dispersed, used in automotive and other traffic tools. Tempered glass impact force to require larger broken, once broken, one-piece glass burst into numerous tiny particles, only some broken glass frame. Ordinary glass a bump is broken, the broken situation of typical, produce many long sharp mouth pieces. Wire broken glass, mirror tooth fragments surrounded by a hole, and in the penetrating point around have more pieces of glass, metal wire fracture length. Discussion on the safety glass safety glass what is? It is in line with national standards of laminated glass, tempered glass, and they produced by the hollow glass, especially the laminated glass and laminated glass hollow glass for the best performance of the integrated. General civil tempered glass is the glass by heat treatment process, make its strength was increased by 3 - 5 times, can withstand a certain degree of energy external impact or temperature changes and do not break, even if broken, is also the whole glass broken into small particles resembling honeycomb obtuse, without hurting people, and have a certain security. Tempered glass can not be cut, need before tempering cut size, and " explode " characteristics. According to different purposes, tempered glass can be divided into full toughened glass, half toughened glass, regional toughened glass, tempered glass, curved tempered glass and other types of. Laminated glass as a kind of safety glass under impact crusher, due to its two common glass sandwiched PVB film bonding, not like ordinary glass broken after the sharp fragments. At the same time, it 's PVB film with sound insulation, solar control properties have made with energy saving, environmental protection function of the new building materials: the use of laminated glass can not only isolated can penetrate ordinary glass 1000 Hz - 2000 Hz with noise, and it can block more than 99% ultraviolet radiation and absorption infrared spectroscopy in the heat. As with the new building materials properties of laminated glass is bound in safety glass use play a huge role in.
