ٹمپرڈ گلاس کی تعریف اور خصوصیات

1. ٹمپرڈ گلاس کی تعریف اور خصوصیات

Tempered glass, also known as strengthened glass, is a kind of prestressed glass. Compressive stress is formed on the surface of the glass through chemical or physical methods, so that when the glass withstands external forces, it first offsets the surface stress, thereby improving the load-bearing capacity and strengthening the glass. Its own resistance to wind pressure, cold and heat resistance, impact resistance, etc. The strength of tempered glass is more than four times that of ordinary annealed glass, and its impact resistance is also greatly improved. In addition, when tempered glass is broken, network cracks will appear or small particles will be produced, which will not hurt people, so it is also called safety glass.

2. Advantages of tempered glass

The advantages of tempered glass are mainly reflected in its strength and safety. First of all, tempered glass is stronger than ordinary glass, but tempered glass has the possibility of self-explosion when the temperature difference changes greatly, while ordinary glass does not have the possibility of self-explosion. Secondly, the surface of tempered glass will be uneven and slightly thinner. The reason for the thinning is that after the glass is softened by hot melt, it is quickly cooled by strong wind, which reduces the crystal gap inside the glass and increases the pressure. Therefore, the glass is thinner after tempering than before. Generally, 4-6MM glass becomes 0.2-0.8MM thinner after tempering, and 8-20MM glass becomes 0.9-1.8MM thinner after tempering.

3. Application of tempered glass

Tempered glass is widely used in various fields. In the construction field, tempered glass can be used in doors, windows, curtain walls, indoor partition glass, lighting ceilings, sightseeing elevator passages, furniture, glass guardrails, etc. In the furniture manufacturing industry, tempered glass can be used in glass coffee tables, furniture accessories, etc. In the home appliance manufacturing industry, tempered glass can be used in televisions, ovens, air conditioners, refrigerators and other products. In the electronics and instrument industries, tempered glass can be used in a variety of digital products such as mobile phones, MP3s, MP4s, and watches. In the automobile manufacturing industry, tempered glass can be used in automobile windshields, etc. In the daily products industry, tempered glass can be used in glass cutting boards, etc. In special industries, tempered glass can be used in military glass.

4. Precautions for tempered glass

When using tempered glass, you need to pay attention to the following points: First, tempered glass cannot be cut or processed. The glass can only be processed to the required shape before tempering, and then tempered. Secondly, although tempered glass is stronger than ordinary glass, tempered glass has the possibility of self-explosion (breaking by itself) when the temperature difference changes greatly, while ordinary glass does not have the possibility of self-explosion. Thirdly, the surface of tempered glass will be uneven and slightly thinner. The reason for the thinning is that after the glass is softened by hot melt, it is quickly cooled by strong wind, which makes the crystal gap inside the glass smaller and the pressure larger. Therefore, the glass is thinner after tempering than before. Generally, 4-6MM glass becomes 0.2-0.8MM thinner after tempering, and 8-20MM glass becomes 0.9-1.8MM thinner after tempering.

In general, tempered glass is widely used in various fields because of its high strength and safety, providing great convenience and safety to our lives.
