The tempered glass belongs to the safe glass. In fact, the tempered glass is a kind of prestressed glass. In order to improve the strength of the glass, it usually uses chemical or physical methods to make the glass steel furnace pressure stress on the glass surface. When the glass bears the external force, it first counteracts the surface force, thus improving the bearing capacity, enhancing the anti wind pressure, the heat and the shock, and so on. The following Luoyang Shen Cheng Glass Technology Co., Ltd. related personnel on the toughened glass advantages and disadvantages gave us a detailed introduction, come and learn!


The strength is several times higher than that of ordinary glass and bending resistance.
Second is the use of safety, its bearing capacity is increased to improve the fragile nature, even if the steel glass destruction is also a small fragment with no sharp angle, the damage to the human body is reduced. The tempered and chilling heat resistance of the tempered glass is 2~3 times higher than that of the ordinary glass. It can generally bear the temperature difference above 150C, and it has obvious effect on preventing thermal explosion.
Safety: when the glass is destroyed by external forces, the fragments become honeycomb like smashed obtuse particles, which are not easy to cause harm to the human body.
High strength: the impact strength of tempered glass of the same thickness is 3~5 times that of ordinary glass, and the bending strength is 3~5 times that of ordinary glass.
Thermal stability: tempered glass has good thermal stability, can withstand temperature difference is 3 times of ordinary glass, can withstand 150 degrees of temperature difference.
The flat and flexural glass belongs to the safe glass. Widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, lighting ceiling, sightseeing elevator channel, furniture, glass guardrail and so on.


1. The glass after steel can not be cut and processed again. The glass can only be processed to the required size and shape before the steel is tempered, and then the steel is tempered.
2. Although the strength of the tempered glass is stronger than that of the ordinary glass, the tempered glass has the possibility of self explosion (self rupture) when the temperature difference is large, and the ordinary glass does not have the possibility of self explosion.
Measures to avoid: after glass steel, the glass surface resistance to mechanical strength is 3~5 times higher than that of ordinary glass, but the edge angle of the tempered glass is relatively fragile and may break after the external force. In addition, if the outside temperature changes frequently, tempered glass may explode. The relevant people remind the public in the use of tempered glass products, should pay attention to not bump the edge corner, it is suggested that try not to make violent changes in glass temperature, so as to avoid spontaneous explosion.
Scope of application: due to the breakage of tempered glass, the debris will break into small particles and have no sharp sharp angle, which is called safe glass and widely used in automobiles, interior decoration, and windows open to the high floor.
Emergency method
Safety pounding: an auxiliary escape tool in a closed cabin. It is usually installed in the place where the car and other closed cabin are easy to take. In emergency cases, such as the fire in the car or the car falling into the water, it can be easily removed and broken to break the glass window door to escape smoothly.
Usage: mainly used for breaking glass in emergency, and the tail blade of hammer handle is used for cutting safety belt escape.


Scope: it is mainly used for vehicle configuration of buses, passenger cars and trains.
How to use it: the safety hammer is mainly made of its conical, because the contact area of the pointed head is very small, so when the glass is smashed with the hammer, the contact point is quite big to the glass pressure (not pressure, but the pressure per unit area). This is a little similar to the principle of the tack. The membrane is easily pierced and makes the car glass. The point is slightly cracked by a large external force, and for the tempered glass, a little cracking means that the stress distribution inside the whole glass is damaged, resulting in a myriad of spider web cracks at the moment, and at this time the glass fragments can be removed by a gentle blow of a hammer.
In addition, the middle part of tempered glass is the most solid, and the four corners and edges are the weakest. The approach is to beat the edges and four corners of the glass with a safety hammer, especially in the middle of the top of the glass. Once the glass has a crack, it is easy to smash the whole glass.


Luoyang Shen Cheng Glass Technology Co., Ltd. is newly developed and made of small tempered equipment. It is cheap, time saving, electricity saving and labor saving are very suitable for the friends of the cabinet industry. We always adhere to good faith and help our customers
