Tempered glass is a safety glass. Tempered glass is truly a kind of prestressed a glass. In order to improve the strength of the glass, chemical or physical methods tend to be used to form compressive stress around the surface of the magnifying glaas. When the glass is suffering from external force, the floor stress is first countered, thereby improving the keeping capacity and enhancing the resistance from the glass itself. Wind demand, cold and heat, impact and so on.
The first is that this strength is several times higher than that of ordinary glass in fact it is resistant to bending.
The 2nd is safe use, and also its increased carrying ability improves the fragile nature. Even if the tempered glass reduces, it will show small fragments without sharp sides, and the damage to the human body is reduced. The quenching and super fast heat properties of Laminated insulated glass are 2-3 times higher than of which of ordinary glass, and generally can face up to temperature changes of 150 C or even more, which has obvious effects on preventing thermal cracking.
Protection: When the glass is usually destroyed by external force, the fragments become little, obtuse-angle particles resembling honeycombs, which are not simple to cause harm to the body.
High strength: The impact strength of tempered glass with the same thickness is Less than 6 times that of ordinary glass, and the bending strength is Less than 6 times that of standard glass.
Thermal stability: Tempered goblet has good thermal steadiness, can withstand a temperature difference of 3 x that of ordinary goblet, and can withstand the temperature difference of 150 °C.
use:
Flat steel and bent tempered glass belong to safety glass. Widely used in high-rise building doors along with windows, glass curtain wall, indoor partition glass, light ceiling, sightseeing elevator admittance, furniture, glass railings, or anything else.
Disadvantages of tempered goblet:
1. The tempered glass still can't be cut and ready-made. The glass can just be processed to the required decorations before tempering, and subsequently tempered.
2. Although the actual strength of tempered glass is stronger than which of ordinary glass, tempered glass has the chance of self-explosion (self-rupture) if the temperature difference changes greatly, while ordinary glass would not have the possibility with self-explosion.
Avoidance measures: Following glass tempering, the mechanical strength with the glass surface is 3 to 5 times higher than in which of ordinary glass, but the tempered glass corner is relatively fragile and may break after being afflicted by external force. In add-on, if the outside temp changes frequently, tempered glass also can self-explosion. Relevant persons are reminded that when utilizing tempered glass products, they should be careful not to bump the corners. It's advocated that the temperature on the glass should not be changed drastically in order to avoid self-explosion.
Scope of software: Since the tempered goblet is broken, the fragments will bust into uniform small particles and now have no common glass chef knives. It is called safety glass and is particularly widely used in autos and interior decoration, as well as high floors. window.
Disaster method:
Safety 捶: An auxiliary escape tool in a very closed compartment. It is generally installed from a place that is easy to get at in a closed compartment for instance a car. In an emergency say for example fire or a car falling on the water, it is convenient to take out and smash the cup window door to evade smoothly.
Uses: Mainly used to break glass escape within emergency situations, the hammer handle tail blade is used to cut the couch belt to escape.
Probability: Mainly used for bus, passenger vehicles, trains and some other vehicle configurations.
How to utilize: The safety hammer largely uses its conical rule. Since the contact class of the tip is little, the pressure of the contact point against the glass when using the hammer glass (not your pressure, but the pressure per unit area) Fairly large, this is just like the principle of the pushpin, that film is easily punctured, and the car glass is afflicted by a large external force in this article to produce a minor crack, and for tempered goblet, a little cracking This means that the stress distribution inside whole glass is destroyed, so that numerous crawl web cracks are generated in an instant. At this time, the glass fragments could be removed by gently rubbing which has a hammer.
In addition, the middle portion of the tempered glass is the strongest, and the four corners along with the edges are the weakest. The best way is always to hit the edge and four corners on the glass with a safe practices hammer, especially in the middle of the upper edge in the glass. Once the cup has cracks, it is easy to smash the completely glass.
Characteristics of tempered cup: Tempered glass is which will heat the high-quality float glass nearby the softening point, and rapidly cool the glass surface to distribute the compressive stress on the glass surface, while the tensile stress is within the center layer. Because of the strong equal compressive strain, the tensile stress generated because of the external pressure is offset with the strong compressive stress of the glass, thereby increasing the safety from the glass.
1. Increased durability: After tempering, the kinetic strength, impact resistance and flexural strength of the glass can reach 4-5 periods that of ordinary glass.
2, the thermal solidity is improved: tempered glass can withstand a substantial temperature difference without destruction, and the resistance to help variable temperature difference is three times that of ordinary float glass of the same thickness.
3, your safety is improved: following a tempered glass is damaged by strong, it will immediately show the tiny obtuse-angle dust, thus maximizing personal security. Applications: furniture, electrical along with electronic industry, construction, adornment industry, bath rooms, cars, escalators, and other sites where safety and temperatures differences are particularly necessary, and can be used as the original film of insulating glass and laminated goblet.
