Transparent quartz heating furnace tube
Transparent quartz heating furnace tube is a heating element made of high-transparent quartz glass, which has a series of unique technical characteristics and a wide range of application fields.
Appearance and structure
Appearance: The surface of the transparent quartz heating furnace tube is made of highly transparent quartz glass, which has good light transmittance.
Structure: The inside of the furnace tube usually contains a resistance wire as a heating element. The outer edge of the resistance wire is larger, and sometimes a lining is set between two layers of quartz glass to prevent the resistance wire from tilting and causing a short circuit, thus increasing its lifespan.
Technical characteristics
High temperature resistance: The softening point temperature of quartz glass is about 1730℃, and it can be used for a long time at 1150℃. The maximum temperature for a short time can reach 1450℃. Therefore, the transparent quartz heating furnace tube can withstand the working requirements under high temperature environment.
Corrosion resistance: Except for hydrofluoric acid, high-purity quartz furnace tubes hardly react chemically with other acids. At high temperatures, it can withstand the erosion of sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon, and sulfur, etc. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel.
Good thermal stability: The thermal expansion coefficient of high-purity quartz furnace tubes is extremely small, and they can withstand drastic temperature changes. Even if the high-purity quartz furnace tubes are heated to about 1100℃ and placed in water at room temperature, they will not burst.
Good light transmittance: High-purity quartz furnace tubes have good light transmittance in the entire spectral band from ultraviolet to infrared, and the visible light transmittance is more than 93%. Especially in the ultraviolet spectral region, the transmittance can reach more than 80%.
Good electrical insulation performance: The resistance value of the high-purity quartz furnace tube is equivalent to ten thousand times that of ordinary quartz glass, making it an electrical insulation material. Even at high temperatures, it also has good electrical properties.
Application field
Transparent quartz heating furnace tubes, due to their unique technical characteristics, are widely used in various occasions that require high-temperature heating and corrosion resistance. For example:
Glass industry: It is used in the processes of hot bending and folding of glass, with fast heating and good bending effect.
Drying room, drying oven: used for drying and heating various materials.
High-end glassware and tableware: They require high-temperature heating and precise temperature control during the manufacturing process.
Transparent quartz heating furnace tubes have the advantages of high temperature resistance, corrosion resistance, good thermal stability, good light transmittance, and good electrical insulation, etc., and are widely used in various occasions that require high temperature heating and corrosion resistance.
