There are many subdivision products of borosilicate glass. Due to the differences in the production process and technical difficulty of borosilicate glass in different product fields, the number of industry enterprises is different, and the market concentration is different.
High borosilicate glass, also known as hard glass, is a glass that is processed by advanced production technology by utilizing the properties of glass to conduct electricity at high temperature, and by heating inside the glass to achieve glass melting. The thermal expansion coefficient of high borosilicate glass is low. Among them, the linear thermal expansion coefficient of “borosilicate glass 3.3″ is (3.3±0.1)×10-6/K. The content of borosilicate in this glass composition is relatively high, respectively. 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 ordinary glass, it has no toxic and side effects. Its mechanical properties, thermal stability, chemical stability, light transmittance, water resistance, alkali resistance, acid resistance and other properties are better. high. Therefore, high borosilicate glass can be widely used in chemical, aerospace, military, family, hospital and other fields, and can be made into lamps, tableware, standard plates, telescope pieces, washing machine observation holes, microwave oven plates, solar water heaters and other products.
With the accelerated upgrading of China’s consumption structure and the increase in the market awareness of high borosilicate glass products, the demand for high borosilicate glass daily necessities has continued to grow. The glass market demand shows a rapid growth trend. According to the “2021-2025 China High Borosilicate Glass Industry Market Monitoring and Future Development Prospect Research Report” released by Xinsijie Industry Research Center, the demand for high borosilicate glass in China in 2020 will be 409,400 tons, a year-on-year increase of 20%. .6%.
There are many subdivision products of borosilicate glass. Due to the differences in the production process and technical difficulty of borosilicate glass in different product fields, the number of industry enterprises is different, and the market concentration is different. There are many production enterprises in the field of medium and low-end borosilicate glass such as craft products and kitchen supplies. There are even some workshop-style production enterprises in the industry, and the market concentration is low.
In the field of high borosilicate glass products used in the fields of solar energy, construction, chemical industry, military industry, etc., due to relatively large technical difficulties, high production costs, relatively few enterprises in the industry, and relatively high market concentration. Taking high borosilicate fireproof glass as an example, there are currently few domestic enterprises that can produce high borosilicate fireproof glass. Hebei Fujing Special Glass New Material Technology Co., Ltd. and Fengyang Kaisheng Silicon Material Co., Ltd. have relatively high market shares. .
Industry researchers from Xinsijie said that domestically, the application of high borosilicate glass still has a lot of room for improvement, and its huge development prospects are unmatched by ordinary soda-lime-silica glass. Scientific and technological workers from all over the world have paid great attention to borosilicate glass. With the rising requirements and demands for glass, borosilicate glass will play an important role in the glass industry. In the future, high borosilicate glass will develop in the direction of multi-specification, large-size, multi-functional, high-quality and large-scale.
