High temperature quartz chip, quartz glass sight glass, transparent quartz glass

Tai professional production of high temperature quartz chip, quartz, as the lens, high temperature quartz glass, high temperature quartz glass tube. Quartz glass, quartz glass grinding usually cut from its silica content up to 99.99%. Mohs hardness of seven, with high temperatures, low coefficient of thermal expansion, thermal shock resistance and good electrical insulation properties and other characteristics. Usually colorless and transparent type, visible light transmittance of more than 85%. First, the optical performance of the optical properties of the quartz glass has its own unique, it can through the far ultraviolet, UV transparent material all the best person, but also near-infrared through visible light spectrum. Since quartz glass high temperature, low thermal expansion, chemical stability, bubbles, stripes, uniformity, birefringence can be comparable with conventional optical glass, so it works with high stability optical system under worst situations essential optical material. Their optical properties can be divided into three categories: Second, the physical properties of the quartz glass is silica glass manufacturing special industrial technology, is a very good base material. Quartz glass with a series of excellent physical and chemical properties, such as: 1, high temperature. Quartz glass softening temperature is about 1730 ℃, prolonged use at 1200 ℃, short-term maximum temperature up to 1450 ℃. 2, corrosion-resistant. In addition to hydrofluoric acid, the quartz glass hardly occurs acids and other chemical reactions, which acid is 30 times the capacity of a ceramic, stainless steel 150 times, especially in the chemical stability at high temperatures, any other engineering materials are unable to match. 3, good thermal stability. Adaptation of the thermal expansion coefficient of glass is extremely small, can withstand severe temperature changes, quartz glass is heated to about 1200 ℃, into the water at room temperature will not burst. 4, good light transmission. Quartz glass in the ultraviolet to infrared spectral bands have to pay a good overall light transmission properties, visible light transmittance of 93% or more, particularly in the ultraviolet region of the spectrum, the maximum transmission rate of up to 80 or more. 5, good electrical insulation properties of quartz glass. The resistance of quartz glass is equivalent to one million times that of ordinary glass, is an excellent electrical insulating materials, even at room temperature also has good electrical properties. Third, the application of quartz glass is formed as a result of its high melt viscosity due to high temperature. For the production of semiconductors, electric light source, a semiconductor communication devices, lasers, optical instruments, laboratory equipment, electrical equipment, medical equipment and high-temperature corrosion-resistant chemical equipment, chemical, electronics, metallurgy, building materials and defense industry, application very extensive. Tianjin Tai high precision quartz glass technology production of special glass, no bubbles, smooth surface, corrosion resistance, light transmission is good, especially for optical, electronic, chemical, military and other optical instruments window observation window. 7 days of delivery, quality assurance, excellent inexpensive price, a variety of thickness according to user needs production, bulk orders can provide 17 percent value-added tax invoices. Jintai heat strengthened glass sight glass product advantages: short production cycle, quality assurance, excellent inexpensive price, delivery on time, able to provide our clients with excellent professional service.
