Is bulletproof glass different from tempered glass? Can bulletproof glass be tempered?

Bulletproof anti-theft glass

        The bulletproof anti-theft glass is scientifically combined with a plurality of transparent float glass of different thicknesses and a plurality of PVB films. In order to enhance the anti-theft performance of the glass, the thickness of the glass and the thickness of the PVB are increased. Due to the adhesion of the glass and the PVB film. It is very strong, almost a whole, and PVB film has good toughness due to the high hardness of glass. When the bullets touch the glass, their impact energy is weakened to a very low level or even zero, so they cannot be worn. Similarly, the impact of metal can only break the glass and can not penetrate, so it plays the role of anti-theft anti-theft. The thickness of each piece of glass and the total thickness of the finished glass depends on the place of use.

        Bulletproof anti-theft glass can be used as military defense, guard glass for bank counters, jewelry jade, gold and silver jewelry and other valuable display cabinets and other specific work and living places.

        Tempered glass is processed by ordinary flat glass or float glass. Ordinary flat glass requires special products or first-class products; float glass requires superior or first-class products.

        There are two kinds of tempered glass production methods: one is to process ordinary flat glass or float glass under special process conditions by quenching method or air-cooling quenching method. The other is to use ordinary flat glass or float glass. Through the ion exchange method, the surface composition of the glass is changed, and the surface of the glass is formed into a laminated stress layer.

        Tempered glass has high impact strength (4~5 times higher than ordinary flat glass), high flexural strength (5 times higher than ordinary flat glass), good thermal stability, smooth, transparent, and cuttable. When the impact is broken, the fragments are scattered and fine particles, and there is no sharp edge, so it is also called safety glass.

        Tempered glass is divided into flat tempered glass and curved tempered glass according to its shape. The thickness of flat tempered glass is 4, 5, 6, 8, 10, 12, 15, and 19 mm; the thickness of curved tempered glass is 5, 6, and 8 mm.

        Tempered glass is divided into two categories according to its appearance quality: excellent products and qualified products.

        Tempered glass is divided into pieces according to the state of fragments: Class I, Class II and Class III.

The standard of bulletproof glass is not allowed to be tempered.

         1. If the bulletproof glass is tempered after receiving the impact, the film in the middle of the granular breakage of the tempered glass is soft and the whole glass is easily collapsed. The ordinary glass is broken after being impacted, and the rigidity of the glass is not the graininess. The effect is still

         2. The tempered glass is broken after being impacted. The line of sight inside and outside the counter is completely blocked. The personnel inside the counter are completely unaware of the outside situation. Reasonable protective measures cannot be taken in time.
