General introduction: Quartz tube is a kind of special industrial glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. Used in electric fire barrel, electric oven, electric heater, heating effect.
Chemical properties:
1, high temperature resistance
The softening temperature of quartz glass is about 1730ºC, and it can be used for a long time at 1100ºC, and the highest temperature can be used for a short time up to 1450ºC.
2, corrosion resistance
Quartz glass almost no chemical reaction with other acids, its acid resistance is 30 times of ceramic, 150 times of stainless steel, especially in high temperature chemical stability, is unmatched by any other engineering materials.
Physical properties:
1, good thermal stability
Quartz glass thermal expansion coefficient is very small, can withstand drastic temperature changes, the quartz glass heated to 1100ºC or so, put into normal temperature water will not burst.
2, good light transmission performance
Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared, the transmittance of visible light is more than 93%, especially in the ultraviolet spectral region, the maximum transmittance can reach more than 80%.
3, good electrical insulation performance
The resistance of quartz glass is equal to 10,000 times that of ordinary glass. It is an excellent electrical insulation material and has good insulation performance even at high temperature.
Mainapplications:
Quartz glass is widely used in electric light source, semiconductor, optical communication, metallurgy, building materials, chemistry, machinery, electric power, environmental protection and other fields due to its excellent physical and chemical properties.
