WHAT IS TEMPERED GLASS

The development of tempered glass can be traced back to the mid-17th century. A Rhineland prince named Robert once conducted an interesting experiment. He placed a drop of molten glass in ice-cold water, and the result was a glass Extremely hard glass. This high-strength granular glass resembles water droplets with long, curved tails and is called "Prince Robert granules." But when the tail of the particle is bent and broken, the strange thing is that the entire particle suddenly collapses violently and even turns into fine powder. The above method is very similar to the quenching of metal, but this is the quenching of glass.

This kind of quenching does not cause any change in the composition of the glass, so it is also called physical tempered. Therefore, tempered glass is called tempered glass.

Tempered glass/Reinforced glass is safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external forces, it first offsets the surface stress, thereby improving the load-bearing capacity and enhancing the glass's own resistance. Wind pressure, cold and heat, impact, etc.

Advantage：

The first is that its strength is several times higher than that of ordinary glass and it is resistant to bending.

The second is that it is safe to use. Its increased load-bearing capacity improves its fragile nature. When the glass is damaged by external forces, the fragments will break into small obtuse-angled particles similar to honeycombs, which greatly reduces the damage to the human body. The resistance to rapid cooling and rapid heating of tempered glass is 3 to 5 times higher than that of ordinary glass. It can generally withstand temperature changes of more than 250 degrees, and has a significant effect on preventing thermal explosions. It is a kind of safety glass. Provide qualified materials to ensure the safety of high-rise buildings.

Third, the impact strength of high-strength tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass. Thermal stability: Tempered glass has good thermal stability and can withstand a temperature difference 3 times that of ordinary glass, and can withstand a temperature change of 300°C.

Applications:

Flat tempered and curved tempered glass are safety glass. It is widely used in high-rise building doors and windows, glass curtain walls, indoor partition glass, lighting ceilings, sightseeing elevator passages, furniture, glass guardrails, etc. Usually tempered glass can be used in the following industries:

⒈Construction, building formwork, decoration industry (for example: doors, windows, curtain walls, interior decoration, etc.)

⒉Furniture manufacturing industry (glass coffee table, furniture accessories, etc.)

⒊Home appliance manufacturing industry (TVs, ovens, air conditioners, refrigerators, etc.)

⒋Electronic and instrument industries (mobile phones, MP3, MP4, watches and other digital products)

⒌Automobile manufacturing industry (automotive window glass, etc.)

⒍Daily products industry (glass cutting boards, etc.)

⒎Special industries (glass for military use)

Because when tempered glass is broken, the fragments will break into uniform small particles without the common glass knife-like sharp corners. Therefore, it is called safety glass and is widely used in automobiles, interior decoration, and windows that open to the outside on high floors.

Since the 1970s, tempered glass technology has been fully promoted and popularized around the world. Tempered glass has been used in automobiles, construction, aviation, electronics and other fields, especially in construction and automobiles, which has developed the fastest.
