The meaning of glass
Tempered glass / Reinforced glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass is subjected to external force, it firstly counteracts the surface stress so as to increase the carrying capacity and enhance the self- Wind pressure, cold summer, impact and so on. That toughened glass protective film is how come? Please read below
Tempered glass protective film formation process
In fact, toughened glass protective film is produced by the glass after tempering, which uses the material AF proof PET material. This formed a tempered glass protective film = glass + steel + AF + explosion + PET on the emergence of new products.

Source of development of glass
The development of toughened glass dates back to the mid-17th century. One of the Rhine princes, Robert, who had done an interesting experiment, put a drop of molten glass in cold water and made a Very hard glass. This high-strength granular glass is like a drop of water with a long, curved tail called "Prince Robert". However, when the tail of the pellet is bent and broken, it is surprising that the whole pellet therefore suddenly and violently collapses, and even becomes a fine powder. This practice, much like metal quenching, which is quenching glass. This quenching does not make any change in the composition of the glass, so it is also called physical quenching (physical tempered), so tempered glass called tempered glass, also known as quenched glass.
When the glass is destroyed by external forces, the debris will be similar to the honeycomb obtuse small particles, not easy to cause serious harm to the human body.
Tempered glass has good thermal stability, can withstand the temperature difference is 3 times the ordinary glass,
Can withstand 300 ℃ temperature changes.
