Glass Is Not Add A Film Called What Bullet-proof Steel

- Nov 22, 2016-

Bullet-proof glassthat is a laminated glass, made of multi-storey high-strength glass, can withstand the pistol or submachine gun shooting, used in banks or luxury and other safety requirements are very high decoration works.

Bulletproof glass is made of glass (or plexiglass) and high-quality engineering plastics by a special processing of a composite material, it is usually transparent material, usually including polycarbonate layer in the ordinary glass layer. Bullet-proof glass is actually made of a combination of transparent sheets of glass or high-strength organic sheets bonded together.

Bullet-proof glassgenerally has the following three-tier structure:

1.Bearing layer

The first layer to withstand the impact of rupture, the general use of thick, high strength glass, can destroy the warhead or change the shape of the warhead, it lost the ability to move forward.

2. Transition layer

General use of organic bonding materials, strong bonding, light fastness, and can absorb part of the impact energy, change the direction of the bullet. In the laminated glass clip a layer of very strong and transparent chemical film. This not only can effectively prevent the bullets shooting, but also has anti-surge impact, anti-blast, shock and impact does not appear after cracking and other properties.

3. Security protective layer

This layer of high-strength glass or high-strength transparent organic material, has good flexibility and toughness, can absorb most of the impact energy, and to ensure that the bullet can not pass through this layer.

Different manufacturers of different bullet-proof glass. But basically in the ordinary glass layer of polycarbonate material in the folder layer, this process is called lamination. In this process, the formation of a similar to ordinary glass but thicker than ordinary glass material. Polycarbonate is a rigid transparent plastic - it is commonly referred to by its brand (Lexan, Tuffak or Cyrolon). The thickness of the bulletproof glass is between 7mm and 75mm.

Bullet-proof glass how to do bullet-proof?

The bullets on the bulletproof glass will break down the outer glass, but the polycarbonate glass layer absorbs the energy of the bullet, preventing it from penetrating the inner glass. These large pieces of bullet-proof glass have been made public during the Second World War, usually between 10.0 and 12.0 centimeters thick, and are extremely heavy.

So is it as long as the bulletproof glass is completely bulletproof?

This is mainly related to the following three factors:

1. The total thickness of the bullet-proof glass is directly proportional to the ballistic effect

Bullet-proof glass thicker, bullet-proof effect of course, the better.

2. Bullet-proof glass structure in the film thickness and anti-ballistic effect

Such as the use of 1.52mm bullet-proof glass bullet-proof glass is better than the use of 0.76mm film of bullet-proof glass.

3. Glass and bullet-proof effect

The use of tempered glass made of explosion-proof glass, its bullet-proof effect is better than ordinary glass-made bullet-proof glass.
