Tempered glass is a kind of glass that is opposite to ordinary glass. It is heated and cooled by physical and chemical methods during the production of glass, and then forms a compressive stress on the surface of the glass. When the glass is intruded by external pressure, The external pressure should be offset by the external pressure to improve the bending and impact strength of the glass and enhance the function. It is a kind of pre-stressed glass, which is a kind of pre-sharpened glass made by processing on the basis of general glass, with high safety function.

difference

　　1 、 Tempered glass has high impact strength, which is 4-5 times that of general glass, the degree of bending resistance is 5 times that of general glass, and the degree of tensile strength is that of general glass {{3 }} Times more.

　　2, tempered glass also has the characteristics of thermal stability, lubricity, transparency, and cutting. It is not simply broken when subjected to a strong impact. Even if it is broken, it will appear in the form of scattered fine particles without sharp angles. The damage to the human body is lowered, so it is also known as safety glass. However, the sharp sharp corners after the general glass is broken can easily cause physical damage to children and impactors. Observe the shape of the glass after the glass is broken. This is a big difference between the two.

Extended data

Tempered glass is heat-treated glass, which is characterized by forming a compressive stress layer on the surface of the glass. The mechanical strength and thermal shock resistance have been improved, and it has a special fragmentation condition.

The carrying capacity of tempered glass is about five times that of ordinary glass, but like other types of glass, it will break when subjected to external forces such as collision and scratching. The edge of tempered glass is a sensitive and thin part of the external force. When the tempered glass is broken, it will make a huge noise, and the fragments will be granular and scattered around. The fragments of tempered glass will not have a significant acute angle. Generally, the broken glass will form sharp fragments and may form severe damage.
