Our company mainly produces high borosilicate glass tube, high borosilicate glass rod and all kinds of high borosilicate processing products. High borosilicate glass (also known as hard glass) is also called "borosilicate glass 3.3" because of its linear thermal expansion coefficient of (3.3 ± 0.1) × 10-6 / K. It is a special glass material with low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft jewelry and other industries. Its good performance has been widely recognized by all walks of life in the world, especially in the field of solar energy.
1. Because of its excellent performance, it is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light source, craft accessories and other industries. The good performance of high borosilicate glass has been widely recognized by all walks of life in the world, especially in the field of solar energy.
2. Borosilicate glass is made by adding sodium silicate sand, soda water and ground lime to the glaze made of boron traditional glass. As borosilicate glass melts at a higher temperature than ordinary silicate glass, some new technologies are needed for industrial production.
3. High borosilicate glass has a very low coefficient of thermal expansion and high temperature resistance, and can withstand the temperature change of 200 ℃. High borosilicate glass is used for reflecting heat-resistant lamp cup of halogen lamp and electrical equipment that must use heat-resistant glass, such as special glass turntable for microwave oven, lampshade for microwave oven, stage light reflecting cup, observation window of drum washing machine, heat-resistant teapot and cup, solar collector tube, etc.
