B orosili cate 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, because the expansion coefficient of line heat (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 by all circles of the world, especially in the solar energy field. The developed countries such as Germany, America and the United States have already carried out more extensive promotion.Borosilicate glass (aka hard glass), is the use of glass in the condition of high conductive properties, through the glass heating...

High temperature resistant glass  is relatively semi-tempered high temperature resistant glass, it is through the high temperature annealing treatment, the glass surface to form a super compressive stress, while the glass mechanical strength has also been strengthened special glass. After the steel heat treatment of glass surface stress is generally between 80 ~ 200Mpa. Which is characterized by broken broken obtuse angle particles, the degree of damage to the human body greatly reduced. Its strength is 4-5 times the strength of ordinary glass, semi-tempered high temperature glass 2-3 times, and has good thermal stability, heat treatment after the high temperature tempered glass, can withstand 180 ℃ -200 ℃ hot and cold Repeated temperature difference test. Semi-tempered high temperature glass applications mainly confined to the dining table and the like, in large construction and industrial machinery and equipment, are not allowed to use semi-steel high temperature glass, for two r...

Heat-resistant glass  (refers to the special heat-resistant boric acid, silicic acid components, can withstand hot and cold fusion temperature changes in the special glass.The coefficient of thermal expansion (the ratio of glass body expansion due to temperature increase) is relatively small,even in the sharp temperature changes are not broken.With low expansion, thermal shock, high temperature, corrosion resistance, high strength and a series of excellent performance.Its raw material prices higher than ordinary glass, manufacturing costs are higher, so the sales price of heat-resistant glass than ordinary glass, tempered glass high.Heat-resistant glass material using high safety factor, will not happen similar to the phenomenon of glass blew blew;thermal expansion coefficient is small, resistant to a wide range of temperature changes (≥ 120 ℃), heat up to the maximum temperature of 1200 ℃.Heat-resistant glass for containers, bottles, experimental beaker, industrial boiler mirror, ...

Borosilicate heat-resistant glass  is a type of "cooked glass", the cost is quite expensive, fully meet the international environmental testing standards. Due to its own heat and anti-instantaneous temperature difference performance requirements, the use of high-boron silicon material to replace the "raw glass" in a large number of lead, zinc and other harmful heavy metal ions, so its brittleness and weight is far less common in life ordinary " But also to ensure that, in the case of instantaneous temperature difference will not burst; its weight, than with a large number of heavy metal ions in the "raw glass" light more; in appearance, it seems with the ordinary glass also has Difference, visually out of the "raw glass" hard, crisp feeling. 1, the composition of raw materials: high borosilicate glass containing boron trioxide and silica in the amount of ordinary glass is higher, even boron content can reach 14%, silicon content of 80%. ...

Crystal glass, ordinary glass and high-borosilicate glass is the main material of glass containers, most manufacturers make high-grade glass containers are selected  high-borosilicate glass , so far the majority of manufacturers on the market indicate the product material is high borosilicate glass. We know that the glass is generally considered the most healthy container due to its stability and transparency. But many people think that in the hot environment, high borosilicate glass will lead to lead, and lead is a toxic substance, this argument is right? High-borosilicate glass has a particularly excellent high temperature resistance, high chemical stability, low expansion rate. It is widely used in pharmaceutical packaging, jewelry, drinking water containers and other products industry.The thermal expansion coefficient of borosilicate glass is (3.3 ± 0.1) × 10-6 / K, also known as "borosilicate glass 3.3. The main component of borosilicate glass is 12.5 ~ 13.5% boron, contai...

Borosilicate glass , English called "borosilicate glass", the main component of alkali borosilicate glass (R2O-B2O5-SiO2) and non-alkali-low silicon borate glass (RO-B2O5-SiO2) glass, add Into the B2O3 borosilicate glass 5 aspects of the effect: 1, eliminate color, increase transparency and clarity. Borosilicate glass due to the relatively high content of B2O3, B2O3 has a superior elimination of glass color difference effect, this has to eliminate the color of the glass, also known as white glass, which in the prism, the lens is actually a wide range of practical production process , An effective solution to the light diffuse reflection and light diffuse problem. 2, thermal stability, a wide range of applications. Borosilicate glass is also known as heat-resistant glass, the thermal expansion coefficient is only 2/5 of ordinary glass, so in household appliances, environmental engineering, chemical engineering, lighting, precision machinery, bio-engineering, safety protect...
