The main component of ordinary glass is silica, which is an amorphous inorganic non-metallic material. It is generally made of various inorganic minerals as the main raw material, while high borosilicate glass is a glass with enhanced fire resistance.On the basis of ordinary glass components, 12.5~13.5% boron is added. In the manufacturing process, glaze water glass sand, soda water and lime also need to be added. The strain temperature can reach 520°C and the strength is higher.
Compared with ordinary glass, it has a lower thermal expansion coefficient: (3.3±0.1)×10-6/K, only about 1/3 of ordinary glass. That is to say, the deformation after heating is smaller, so it is less likely to break after being heated and cooled. Everyone should have this kind of experience, pour boiling water directly into a thicker glass in winter, and the glass will crack immediately.
In addition, water resistance, alkali resistance, acid resistance and other properties are much stronger than ordinary glass.
High borosilicate glass is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. It is widely used because of its excellent performance.
