High temperature resistant glass is relative to ordinary glass, it is a can withstand a certain high temperature, can be used in a variety of high temperature conditions,  heat resistant glass  products. Mainly used for the production and processing of various heat-resistant glass mirror, boiler mirror, industrial mirrors, oven glass, fireplace glass, high temperature glass tube and other products, chemical, petroleum, metallurgy, power, machinery manufacturing and other industries often use To the product. High temperature glass picture Our daily use of glass mainly has three categories: ordinary glass, tempered glass and high temperature glass. Easy to blew the main is ordinary glass and tempered glass. Compared with tempered glass, high temperature glass as high-temperature glass, high-temperature window glass is much more safe, high temperature glass type is more, product thermal expansion coefficient is small, heat resistance, strong resistance to sudden changes in tempe...

Borosilicate glass  forming process technology is melting, clarification, homogenization of the molten glass, high temperature in the tin bath floating in the molten tin liquid surface, the use of molten glass surface tension, glass and tin liquid between the surface Tension, glass liquid gravity to complete the glass liquid leveling, thinning, polishing, cooling, solid and other processes, making it better than polished glass of high quality flat glass. The factors that determine the effect of borosilicate glass formation are glass viscosity, surface tension and self-gravity. In these three factors, the glass viscosity mainly from the role of glass stereotypes, glass surface tension mainly from the role of glass polishing, glass gravity is mainly from the role of glass flattening, the three of the glass liquid leveling, polishing And thinning have a certain role, combined with each other in order to carry out borosilicate glass production. Boron glass under the surface of the am...

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 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%. ...

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, ...

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...

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...

Borosilicate glass  has a high content of SiO2 and B2O3, which makes its network integrity and density than ordinary sodium silicate glass, and has excellent thermal properties. Such as its thermal expansion coefficient is generally less than 60 × 10_7 / ℃, and ordinary sodium silicate glass is about (90 ~ 100) × 101 / ℃. Borosilicate glass thermal shock resistance △ T is generally greater than 150 ℃, known as hard glass or special hard glass, ordinary sodium silicate glass is less than 100 ℃. Therefore, borosilicate glass has good thermal stability, can be used in utensils cooking utensils, building fire and other fields. Because the borosilicate glass has excellent thermal properties, it is safe to make the container.SJZ JINXUAN TRADING CO., LTD.is the  Borosilicate glass   supplie r  .The Expansion coefficient of our product is 3.3-3.8 x106, so all our borosilicate glassware can be used for oven, microwave, freezer and dishwasher safe.

For expensive high temperature glass , the length of life directly affects the cost of production and processing, for the use of units, the longer the life of high-temperature glass, the more able to reduce the cost of production and processing products. There are many factors that affect the service life of a high-temperature glass, and if the user can understand these factors, it will be able to help the unit to extend the service life of the glass to reduce production costs. Let me introduce you to the impact of  high temperature glass  life of several factors: First of all, the quality of glass, a glass of high and low quality, for the life of the glass has an absolute impact on the quality of glass processing and processing and related, so the choice of high-quality glass is to ensure high temperature glass life of the primary conditions. The quality of high-temperature glass mainly refers to the appearance of glass quality and quality of the processing process is good...
