Borosilicate glass (aka hard glass), is the use of glass in the condition of high conductive properties, through the glass heating to realize glass melting, using advanced production process, due to thermal expansion coefficient line for (3.3 + 0.1) * 10-6/K, also known as "borosilicate glass 3.3". It is a special glass material of low expansion rate, high temperature resistance, high strength, high hardness, high transmittance and high chemical stability, because of its excellent properties, is widely used in solar energy, chemical industry, pharmaceutical packaging, electric light, craft accessories industry. Its good performance has been widely recognized all over the world, especially in the field of solar energy has been widely used in developed countries, such as Germany and the United States has carried out fire resistance and physical strength are widely spread borosilicate glass makes it the ideal choice in the laboratory, it is used for the manufacture of laboratory equipment such as beakers and test tubes of high durability the use of glass. In addition, the minimum exposure of borosilicate glass bends allows the precise measurement of the volume of boron silicon heat resistant containers for a period of time.
With the development of electronics, biology, safety, new energy, aerospace and other fields, higher requirements are put forward for the relevant flat glass materials. Among them, the demand for home appliances, such as heat-resistant glass, fireproof glass, solar cell glass, and so on, is also the hot spot of research and development in recent years.
Borosilicate 3.3 is the international standard ISO 3585 standard glass, we do chemical experiment beaker test tube is this kind of glass. Because the linear expansion coefficient of the glass is 3.3 * 10-6K-1, it is referred to as "borosilicate glass", which is called "borosilicate glass", which is called as "borosilicate glass", which is a kind of "borosilicate glass". It is called "borosilicate glass 3.3". Boron silicon 3.3 with low expansion, corrosion resistance and high temperature performance known as the "king of glass" reputation. However, due to its high level of difficulty in the production of flat glass, has been in the special field of industrial applications.
Fire resistant glass is a kind of special glass which can keep its integrality and heat insulation under the condition of fire resistance test. Mainly involves three major application areas: one is the industrial and civil buildings must be equipped with fire protection materials (especially high-rise buildings); two, scientific research and military defense facilities (explosive, flammable, aerospace and biological industrial facilities; three) is material for modern traffic tools supporting fire (especially marine fire-proof glass). The requirements of fire resistant glass are good heat resistance, light weight, no fire and so on. With the development of China's economy, more and more attention has been paid to building safety and fire prevention and disaster prevention in various fields. At present, our products are leading fireproof glass soda lime flat glass cesium potassium tempered, there are natural defects of low softening point, an important place for high-end products still need to import the international mainstream borosilicate glass fire etc..
Borosilicate glass has many excellent properties, such as good thermal stability, chemical stability, mechanical properties, processing properties and optical properties, has been widely used, which can meet the above requirements of the field on the properties of glass. The production of flat glass by float process has many well-known advantages, such as low cost, high yield, good surface quality, and so on. Combined with the advantages of the two methods, the production of borosilicate flat glass by float process is an inevitable trend.
