| Thick-walled quartz tubeOur co***ny specializes in producing thick-walled quartz tube with complete specifications. For more product, more discount.This product, with excellent thermal stability, electrical insulation, transmittance, and acid resistance, is widely used in high-tech field of semiconductor technology, IC manufacturing, optical fiber communications, laser technology, aero***ce technology, national defense and optical industriesThick-walled quartz glass tube is a special industrial technology, thick-walled quartz tube diameter and wall thickness relative terms, usually 3-10mm.Varieties of thick-walled quartz tubes include: cylinder with round inner hole, cylinder with square inner hole, cuboid with inner round hole and fan-shaped hole.Thick-walled quartz tube is widely used in boiler tubes, instrumentation, semiconductor, electric lighting, machinery and other fields.Product has the following series of excellent physical and chemical properties:1. Temperature: softening point temperature of about 1730 degrees Celsius, can be used for long hours at 1100 degrees Celsius, for short-term time the highest degree up to 1450 degrees Celsius temperature; 2. Anti-corrosion: In addition to hydrofluoric acid, the little reaction with the other acids, especially in high temperature, any other engineering materials can not be co***red with its chemical stability; 3. Thermal stability: thermal expansion coefficient of quartz glass is tiny and can withstand drastic temperature changes; 4. Good transmittance: quartz glass in the ultraviolet to infrared spectral bands have a better overall light level, and visible light transmittance of 93% or more, especially in the ultraviolet spectral region, the maximum transmittance up to 80%; 5.good electrical insulation properties: the resistance of quartz glass, ordinary glass is equivalent to a million times, is an excellent electrical insulating materials, even at high temperatures also have good electrical properties. |
