Tempered Glass Has A Good Thermal Stability, Can Withstand The Temperature Difference

Tempered Glass belongs to safety glass. Tempered Glass is actually a kind of prestressed glass, in order to improve the strength of glass, usually using chemical or physical methods, the formation of compressive stress on the glass surface, the glass bear the external force when the first to offset the surface stress, thereby enhancing the carrying capacity, Wind pressure, cold and heat, impact and so on.

Features:

The first is the strength than ordinary glass to improve several times, bending.

The second is the use of safety, its increased carrying capacity to improve the fragile nature, even if the destruction of Tempered Glass was no small angle of small pieces, the damage to the human body reduced. Tempered quenching and cooling properties of Tempered Glass than ordinary glass has 2 to 3 times the increase, generally can withstand more than 150 ℃ temperature difference, to prevent the thermal cracking has a significant effect.

Safety: When the glass is destroyed by external forces, debris into a similar honeycomb-like small obtuse angle particles, not easy to cause harm to the human body.

High strength: the same thickness of the Tempered Glass is the impact of ordinary glass 3 to 5 times the bending strength of ordinary glass is 3 to 5 times.

Thermal stability: Tempered Glass has good thermal stability, can withstand the temperature difference is 3 times the ordinary glass, can withstand 150 ℃ temperature difference.

Use:

Flat steel, bending glass is a safety glass. Widely used in high-rise building doors and windows, glass curtain wall, indoor partition glass, lighting ceiling, sightseeing elevator channel, furniture, glass fence and so on.

Emergency method:

Safety hammer: An auxiliary escape in a closed room. It is generally installed in the car and other enclosed cabin easy to get to the place, in the event of a car fire or car into the water and other emergency situations, you can easily remove and smash the glass window door to escape.

Uses: mainly used in emergency situations to break the glass escape, the hammer handle tail blade used to cut the seat belt escape.

Scope: mainly used for bus, passenger vehicles, trains and other vehicle configuration.

Usage: safety hammer is mainly the use of its conical tip, because the tip of the contact area is very small, so when the hammer hit the glass, the contact point of the glass pressure (not the pressure, but the pressure per unit area) Quite large, this is somewhat similar to the principle of the pushpin, the film is easy to be punctured, and the car glass at that point by a large external force and produce a slight cracking, and for the Tempered Glass, a little bit of cracking Means that the stress distribution within the whole piece of glass has been destroyed, which in the moment produce numerous spider web cracks, this time as long as gently with a hammer and then hit a few times to remove the glass fragments.

In addition, the middle part of the Tempered Glass is the most solid, the four corners and the edge is the weakest. The best way is to use the safety hammer to hit the glass edge and four corners, especially the glass above the edge of the middle of the place, once the glass has a crack, it is easy to smash the whole piece of glass.

Tempered Glass Features: Tempered Glass is a high-quality float glass heating close to the softening point, the rapid cooling of the glass surface, so that the distribution of compressive stress on the glass surface, while the tensile stress in the center layer. Because there is a strong equivalent of compressive stress, so that the external pressure generated by the tensile stress by the glass of the strong compressive stress offset, thereby increasing the safety of the glass.

1, the strength increase: After the glass mechanical strength, impact resistance, bending strength can reach 4-5 times the ordinary glass.

2, increased thermal stability: Tempered Glass can withstand a huge temperature difference without damage, resistance to change the temperature difference is equal to the ordinary thickness of ordinary float glass 3 times.

3, improve the safety: Tempered Glass by the strong damage, the rapid emergence of small obtuse angle particles, so as to maximize the safety of people. Applications: furniture, electrical and electronic industry, construction, decoration industry, baths, cars, escalators, and other special needs of the safety and the existence of temperature drifting places, and can be used as insulating glass and laminated glass of the original film.
