| Tempered glass is 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. The company is located in: The company is located in:advantage The company is located in: First, the intensity increased several times more than ordinary glass, bending. The company is located in: Second, the use of safety, its carrying capacity increased to improve the fragile nature, even if the destruction of tempered glass was also acute small fragments, reducing the damage to the human body. Temperatures of quench-resistant glass are two to three times higher than that of ordinary glass, and can generally withstand the temperature change above 150 ° C, which has a significant effect on preventing thermal cracking. The company is located in: Safety: When the glass is destroyed by external forces, debris into a similar honeycomb-like small obtuse particles, not easy to cause harm to the human body. The company is located in: High strength: The same thickness of the impact strength of tempered glass is ordinary glass 3 to 5 times, bending strength is 3 to 5 times that of ordinary glass. The company is located in: Thermal stability: Tempered glass has good thermal stability, can withstand the temperature difference is 3 times the ordinary glass, can withstand the temperature change of 150 ℃. The company is located in: The company is located in:use: The company is located in: Flat tempered, curved tempered glass is safety glass. Widely used in high-rise building windows and doors, glass curtain wall, indoor partition glass, ceiling lighting, tourism elevator access, furniture, glass fence and so on. The company is located in: The company is located in:Disadvantages The company is located in: 1, tempered glass can no longer be cut and processed, can only be tempered glass before processing to the required size and shape, and then tempered. The company is located in: 2,Tempered glassAlthough the intensity is stronger than ordinary glass, tempered glass has the possibility of self-explosion (self-rupture) when the temperature difference varies greatly, but the ordinary glass does not have the possibility of self-explosion.  Avoid measures: After glass tempering, the mechanical strength of the glass surface is 3 to 5 times higher than ordinary glass, but the tempered glass corner is relatively fragile, which may rupture after being subjected to external force. In addition, if the external temperature changes frequently, toughened glass may also blew. Stakeholders reminded members of the public in the use of toughened glass products, be careful not to bump corners, it is recommended not to make the glass temperature violent changes in order to avoid blew. The company is located in: Scope of application: Since the broken pieces of tempered glass break into even small particles and there is no sharp corner of the glass knife, which is called safety glass and is widely used in automobiles, interior decoration, and high-rise open to the outside window. The company is located in: The company is located in:Emergency method The company is located in: Safety hammer: An auxiliary escape kit in a closed cabin. It is generally installed in easily accessible enclosed spaces such as cars. In emergency situations such as a fire in a car or a car falling into the water, it can be conveniently removed and smashed to facilitate the escape. The company is located in: Uses: mainly used in emergency escape broken glass, hammer handle rear blade for cutting off the seat belt to escape. The company is located in: Range: mainly used for buses, passenger vehicles, trains and other vehicle configuration. The company is located in: How to use: safety hammer is mainly the use of its conical tip, the tip of the contact area is very small, so when using a hammer to hit the glass, the pressure of the contact point on the glass (not pressure, but the pressure per unit area) Quite large, this principle with the thumbtack is a bit similar, the film is very easy to be punctured, and the car glass at this point by a large external force and produce a slight cracking, and for tempered glass, a little cracking This means that the stress distribution inside the monolithic glass has been destroyed, resulting in countless spider web-like cracks in an instant. At this moment, the glass fragments can be removed by just gently striking the hammer a few more times. The company is located in: In addition, the middle of the tempered glass is strong, corners and edges are weak. The solution is to use a safety hammer to beat the edges and corners of the glass, especially in the middle of the upper edge of the glass. Once the glass has cracks, it is easy to smash the whole piece of glass. The company is located in: The company is located in:Tempered glass features The company is located in: The company is located in:Tempered glassWhen the high quality float glass is heated close to the softening point, it is rapidly cooled on the glass surface, so that the compressive stress is distributed on the glass surface, and the tensile stress is in the center layer. Because there is a strong equal compressive stress, the tensile stress caused by external pressure is offset by the strong compressive stress of glass, so as to increase the safety of the glass.The company is located in: 1, increase the strength: After tempered glass mechanical strength, impact resistance, bending strength can reach 4-5 times the ordinary glass. The company is located in: 2, thermal stability: toughened glass can withstand huge temperature without damage, resistance to temperature and temperature difference is the same thickness of ordinary float glass 3 times. The company is located in: 3, increased safety: toughened glass by strong damage, the rapid presentation of small obtuse particles, so as to ensure personal safety. Applications: furniture, electrical and electronic industries, construction, decoration industry, bath, car, escalator, and other special needs safety and temperature changes in the place there, and can be used as the hollow glass and laminated glass of the original film. |
