Tempered glass also known as reinforced glass. The glass is reinforced by tempering method.
1. How is tempered glass made?
1. Cut the ordinary glass into the required size first, and then heat it to about 700 degrees close to the softening point.
2. Fast and uniform cooling (usually 5-6mm glass is heated at 700 degrees high temperature for about 240 seconds, and the temperature is cooled for about 150 seconds. 8-10mm glass is heated at a high temperature of 700 degrees for about 500 seconds and cooled for about 300 seconds. In short, depending on the thickness of the glass, the time for heating and cooling is also different).
II. Advantages and disadvantages of tempered glass
Advantages:
1. Safety: When the glass is damaged by external force, the fragments will become honeycomb-like obtuse angle broken small particles, which is not easy to cause serious harm to human body.
2. High strength: the impact strength of tempered glass with the same thickness is 3~5 times that of ordinary glass, and the bending strength is 3~5 times that of ordinary glass.
3. Thermal stability: tempered glass has good thermal stability, can withstand three times the temperature difference of ordinary glass, and can withstand the temperature difference change of 300℃.
Disadvantages:
1. Tempered glass does not improve the sound insulation performance of doors and windows. It is only from the perspective of safety. Once broken, it will not hurt people. However, it should be noted that tempered glass is most afraid of the impact of sharp objects.
2. The tempered glass can no longer be cut and processed. The glass can only be processed to the desired shape before tempering, and then tempered.
3. Although the strength of tempered glass is stronger than that of ordinary glass, tempered glass has the possibility of self-explosion (self-rupture), while ordinary glass does not have the possibility of self-explosion.
3. When will tempered glass be used in the manufacture of doors and windows?
Tempered glass belongs to safety glass, which is mainly used in the design of doors and windows for the use of large-area glass with a glass area of more than 1.5 square meters at the bottom of floor-to-ceiling windows and areas, ensuring safety and breaking without hurting people. Usually, toughened glass of more than 1 square meter is recommended..
IV. Price of tempered glass
the price of tempered glass is to increase 40 yuan/square meter on the basis of the original window price. If it is double-layer tempered glass, the price is 80 yuan/square meter, and so on. (Please see the latest price price List)
it is not necessary to use tempered glass to decorate and change windows at home. Unless there are special safety needs, you can communicate with the designers of Rixiang door and window factory to determine whether to use tempered glass after determining the design plan.
