根据你的经验判断防弹玻璃

Bullet-proof glass is made of more different thickness of the film transparent float glass and many pieces of PVB film with science combination. In order to strengthen the bombproof and burglarproof functions, the thickness of the glass and PVB were been increased. As the glass and PVB film agglutinate very strong, almost as a whole, and for a higher hardness of the glass and good toughness of PVB film, the impact of energy was been weakened to a very low even to zero when the bullets strike the glass. So it cant penetrate it. Similarly, metals impact can only be shattered glass and cant be penetrated. So bullet-proof is effect. The thickness of single glass and glass production should depend on the use of places. The special glass is made by more than two high-quality float glass with PVB film and processing with a special high-level of safety glass Have good transparency, high mechanical strength, anti-UV, heat insulation, sound insulation, and other characteristics of a bullet-proof. In line with its bullet-proof performance UL752 and GA165-1997 standard.Other Description: film thickness: 0.38,0.76 ,1.522.28 Maximum size: 2100 × 5000 Minimum size: 300 × 300 Thickness :6-60 The kinds of gun for bullet-resistant: 1.7.62mm Steel cored bulletfor F79 Light submachine gun 2.7.62 NATO bullet for F54 handgun 3.7.62 steel cored bullet for F56 submachine gun Standard: GB17840-1999<<Bullet-proof Glass>> Chinese National Standard .
