Quartz tube

الوصف

Quartz tube can be divided into: transparent quartz tube, filter ultraviolet quartz tube, color quartz tube etc. Quartz glass has excellent physical and chemical properties: 1.High temperature resistant: long time working at 1, **0centi degree, for short time working at the highest temperature at ***0centi degree, softening point is ***0centi degree. *****-resistant: except the hydrofluoric acid, it almost has no reaction with acid material, acid-resistant is *0 times to that of ceramics and **0 times that of stainless steel, under the high temperature the chemical properties is stable. ***** thermal stability: thermal expansion coefficient is minimal, can stand the sharp changes in ***** 1, **0centi degree into water of normal room temperature it will not burst. ***** transparency for light: Good transparency from the ultraviolet ray to infrared spectral bands, Visible light transmittances is *3%, ultraviolet spectrum area biggest through rate can reach more than *0%. ***** electrical insulation: High resistance compared with ordinary glass. Applied in the area of light source, semiconductor, telecommunication industry, metallurgy, building materials, chemical, machinery, electric power, environmental protection. Quartz tube can be divided into: transparent quartz tube, opaque quartz tube, filter ultraviolet quartz tube, color quartz tube, etc. Mr.Danny Du
