In depth tempered glass

Recommended Posts


 Tempered glass is usually a safety glass. Tempered glass is truly a kind of prestressed magnifying glaas. In order to increase the strength of the glass, chemical or physical methods are often used to form compressive stress to the surface of the magnifying glaas. When the glass is afflicted by external force, the surface area stress is first counteract, thereby improving the showing capacity and enhancing the resistance with the glass itself. Wind pressure, cold and heat, impact etc ..
The first is the strength is several times beyond that of ordinary glass and it is resistant to bending.

The 2nd is safe use, in addition to its increased carrying capability improves the fragile characteristics. Even if the tempered glass reduces, it will show smaller fragments without sharp sides, and the damage to the human body is reduced. The quenching and fast heat properties of tempered glass are 2-3 times higher than of which of ordinary glass, and generally can tolerate temperature changes of 150 C and up, which has obvious effects on preventing thermal cracking.

Protection: When the glass can be destroyed by external force, the fragments become compact, obtuse-angle particles resembling honeycombs, which are not easy to cause harm to the human body.

High strength: The impact strength of tempered insulated glass of the same thickness is Less than six times that of everyday glass, and the bending strength is 3 to 5 times that of ordinary glass.

Thermal stability: Tempered tumbler has good thermal solidity, can withstand a temperature difference of 3 x that of ordinary tumbler, and can withstand the temperature difference of 160 °C.
use:

Flat steel and bent tempered glass owned by safety glass. Widely found in high-rise building doors and windows, glass curtain wall, indoor partition glass, illumination ceiling, sightseeing elevator obtain, furniture, glass railings, and so on.

Disadvantages of tempered glass:

1. The tempered glass cannot be cut and dealt with. The glass can exclusively be processed to the required decoration before tempering, and next tempered.

2. Although the particular strength of tempered magnifying glaas is stronger than which of ordinary glass, tempered glass has the possibility of self-explosion (self-rupture) once the temperature difference changes enormously, while ordinary glass isn't going to have the possibility regarding self-explosion.

Avoidance measures: After glass tempering, the mechanical strength of the glass surface is Less than 6 times higher than that will of ordinary glass, nevertheless the tempered glass corner is relatively fragile and probably do break after being suffering from external force. In supplement, if the outside heat range changes frequently, tempered glass may self-explosion. Relevant persons are reminded that when utilizing tempered glass products, they should give any attention to bump the corners. It is suggested that the temperature from the glass should not be changed drastically in order to avoid self-explosion.
Scope of job application: Since the tempered glass is broken, the fragments will crack into uniform small particles and get no common glass knives. It is called safety glass and it is widely used in autos and interior decoration, in addition to high floors. window.

Disaster method:

Safety : An auxiliary escape tool inside a closed compartment. It is generally installed from a place that is easily accessible in a closed compartment say for example a car. In an emergency say for example a fire or a car falling in to the water, it is convenient to get and smash the goblet window door to avoid smoothly.

Uses: Mainly used to break glass escape with emergency situations, the hammer handle tail blade is employed to cut the seat belt to escape.

Chance: Mainly used for bus, traveling vehicles, trains and alternative vehicle configurations.

How to use: The safety hammer largely uses its conical word of advice. Since the contact class of the tip is modest, the pressure of the contact point from the glass when using that hammer glass (not your pressure, but the difficulty per unit area) Rather large, this is like the principle of the pushpin, your film is easily punctured, and the car glass is subjected to a large external force now to produce a small crack, and for tempered magnifying glaas, a little cracking Therefore the stress distribution inside the whole glass is wrecked, so that numerous crawl web cracks are generated in an immediate. At this time, the glass fragments might be removed by gently rubbing having a hammer.
In addition, the center portion of the tempered glass will be strongest, and the four corners and also the edges are the weakest. The best way could be to hit the edge and four corners on the glass with a security hammer, especially in the center of the upper edge on the glass. Once the cup has cracks, it is simple to smash the completely glass.

Characteristics of tempered cup: Tempered glass is which is designed to heat the high-quality float glass at the softening point, and rapidly cool your glass surface to deliver the compressive stress within the glass surface, while the tensile stress was in the center layer. With the strong equal compressive worry, the tensile stress generated by the external pressure is offset because of the strong compressive stress in the glass, thereby increasing the safety with the glass.
1. Increased toughness: After tempering, the mechanised strength, impact resistance and flexural strength from the glass can reach 4-5 occasions that of ordinary a glass.

2, the thermal stableness is improved: tempered glass can withstand a big temperature difference without ruin, and the resistance to be able to variable temperature difference is 3 times that of ordinary float glass on the same thickness.

3, this safety is improved: following your tempered glass is damaged by the strong, it will rapidly show the tiny obtuse-angle allergens, thus maximizing personal basic safety. Applications: furniture, electrical as well as electronic industry, construction, furnishings industry, bath rooms, autos, escalators, and other locations where safety and temp differences are particularly necessary, and can be used as the original film of insulating glass and laminated a glass.
