bomb proof glass and other glass:

when ordinary glass (annealed, toughened, semi toughened) is impacted by bomb explosion, glass fragments scatter, glass is penetrably damaged, and personnel and indoor facilities are seriously injured. RET≈. 2。

ordinary laminated glass is often lack of power to configure instruments by bomb enterprises. When it is impacted by explosion, the glass breaks and the shock wave enters the room. In serious cases, the whole broken glass flies up and smashes into the human body, causing serious injury. Therefore, the whole damage range is smaller than that of ordinary glass. RET≈0.. 5。

when the bomb proof glass is impacted by the bomb explosion, the glass bends backward, and the frame system compresses and buffers backward. The glass is complete or broken, but there is basically no debris splashing, so as to ensure that indoor personnel and facilities are not injured. RET≈1.0。

note:

ret: retention value, indicating that the overall polyurethane foam with glass in the frame is an efficient heat insulation material retention

ret= weight of glass after explosion impact/weight of glass before explosion impact

when ret=1.0, the whole glass remains in the frame, the fragments are not scattered, and the glass is not penetrated

when ret=0, the whole glass leaves the frame, and fragments scatter, resulting in penetrating failure

high molecular polymers are generally PVB, and there are other kinds of transparent bulletproof films, but PVB is a commonly used material, Zhonghua glass ()
