There are many subdivided products of high borosilicate glass. Due to the differences in the production process and technical difficulty of high borosilicate glass in different product fields, the number of enterprises in the industry is different, and their market concentration is different.
High borosilicate glass, also known as hard glass, is a glass processed by advanced production technology by using the characteristics of glass to conduct electricity at high temperatures, heating the glass inside the glass to achieve glass melting. High borosilicate glass has a low thermal expansion coefficient. The linear thermal expansion coefficient of “borosilicate glass 3.3″ is (3.3±0.1)×10-6/K. The borosilicate content of the glass composition is relatively high. It is boron: 12.5%-13.5%, silicon: 78%-80%, so it is called high borosilicate glass.
High borosilicate glass has good fire resistance and high physical strength. Compared with common glass, it has no toxic and side effects. Its mechanical properties, thermal stability, chemical stability, light transmittance, water resistance, alkali resistance, and acid resistance are better. high. Therefore, high borosilicate glass can be widely used in various fields such as chemical industry, aerospace, military, family, hospital, etc. It can be made into lamps, tableware, dials, telescopes, washing machine observation holes, microwave oven dishes, solar water heaters and other products.
With the accelerated upgrading of China’s consumption structure and the increasing market awareness of high borosilicate glass products, the demand for daily necessities of high borosilicate glass continues to grow, coupled with the expansion of the application scale of high borosilicate glass in fireproof materials, optics and other fields, driving China’s high borosilicate glass The glass market demand is showing a rapid growth trend. According to the “Market Monitoring and Future Development Prospects Research Report of China’s Borosilicate Glass Industry from 2021-2025″ issued by the New Sijie Industry Research Center, the demand for high borosilicate glass in China will be 409,400 tons in 2020, a year-on-year increase of 20%. 6%.
There are many subdivided products of high borosilicate glass. Due to the differences in the production process and technical difficulty of high borosilicate glass in different product fields, the number of enterprises in the industry is different, and their market concentration is different. There are many production enterprises in the field of low-end and high-end borosilicate glass, such as craft products and kitchen supplies. There are even some workshop-type production enterprises in the industry, and the market concentration is low.
In the field of high borosilicate glass products used in solar energy, construction, chemical, military and other fields, due to the relatively large technical difficulty and high production cost, there are relatively few companies in the industry and the market concentration is relatively high. Taking high borosilicate fire-resistant glass as an example, there are currently few domestic companies that can produce high borosilicate fire-resistant glass.
There is still much room for improvement in the application of high borosilicate glass, and its huge development prospects are unmatched by ordinary soda lime silica glass. Technologists from all over the world have paid great attention to high borosilicate glass. With the increasing demand and demand for glass, high borosilicate glass will play an important role in the glass industry. In the future, high borosilicate glass will develop in the direction of multiple specifications, large sizes, multi-function, high quality, and large-scale.
