What kind of glass is used for the bulletproof car?

For the purpose of bulletproof, the glass must be different from ordinary glass. We generally refer to bulletproof glass. Prior to this, many people mistakenly believe that bulletproof glass is a similar product such as tempered glass. Tempered glass is a kind of prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the glass itself. Compressive, cold and hot, impact and so on. However, it is absolutely impossible to resist the mob's bullets, blunt snoring, and landslides.

The bulletproof glass produced by Shanghai Star Enterprise Development Co., Ltd. can not only resist the bullet attacks, but also block the sledgehammer sticks from being killed for more than 20 minutes. The passengers are still safe.

Where is the mystery of bulletproof glass?

Bulletproof glass is a composite of various high-strength transparent materials. It is a series of transparent composite materials that look like glass but not ordinary quartz glass. Depending on the level of protection, weight and cost, it can be combined with all the super-transparent materials that can be made by human technology such as glass, acrylic, polycarbonate, ceramics.

The most common use of bulletproof glass is the organic combination of laminated glass and high-strength and high-tough polycarbonate. The secret of defense is to transform the kinetic energy of high-speed bullets through the rigid and soft formula and block the spatter caused by the broken glass itself. Secondary damage. Each piece of bulletproof glass produced by Shanghai Star Enterprise Development Co., Ltd. is designed and assembled with the world's top anti-wear polycarbonate sheet. Its impact strength is 250 times that of the same thickness of glass. This is the bulletproof glass that cannot be penetrated or worn. The real mystery lies.

How is bulletproof glass made?

Ordinary bulletproof glass is made up of high-temperature and high-pressure superposition of multi-layer glass and polycarbonate according to different protection level requirements. Each armored car, according to its original windshield and the curvature of the window, the shape and the body installation structure, through the reverse three-dimensional design of professional engineers, mold customization.

A bulletproof glass that can withstand AK47 steel bullets has an areal density 10 times that of ordinary automotive glass. So how to safely and perfectly install each piece of bulletproof glass, and realize the free lifting of the side window glass, not to replace ordinary glass with A bullet-proof glass of the same size is as simple as that. The seemingly thick bullet-proof glass, without a clever and indestructible structural support design, even if it is not broken down after being subjected to bullet baptism, the whole piece of glass may collapse instantly and become a “tofu slag project”, so that it can be protected in a critical moment. The value of life falls short.
