The double-layer glass reactor adopts 3.3 high borosilicate glass, which is a special glass material. It has low expansion rate, high temperature, high strength, high hardness, high light transmittance and high chemical stability. The high borosilicate glass can withstand a temperature difference of about 150℃.
1. The coefficient of thermal expansion of high borosilicate glass is different from that of ordinary glass: high borosilicate glass has a very low coefficient of thermal expansion, which is about one third of that of ordinary glass. This will reduce the impact of temperature gradient stress, so that it has stronger fracture resistance.
2. The main components of high borosilicate glass and ordinary glass are different: ordinary glass is borosilicate glass, and the main component is silicon dioxide. The main components of high borosilicate glass are boron trioxide and silicon dioxide. Soda water and other substances are added in the manufacturing process of ordinary silicate glass. The boron content and silicon content of high borosilicate can reach 14% and 80% respectively, while the ordinary glass does not add boron generally.
3. High borosilicate glass is different from ordinary glass in cold and hot shock resistance: Boron and silicon materials are used in high borosilicate glass to replace a large number of harmful heavy metal ions in raw glass, improve the cold and hot shock resistance of glass, and prevent glass cracking.
4. The tensile strength of high borosilicate glass is different from that of ordinary glass: the tensile strength of high borosilicate glass is higher than that of ordinary glass, so the cracks are large. It is unit breakage, not ordinary glass breakage.
