Large diameter heated quartz glass tube

Large diameter heating quartz glass tube is a special industrial glass tube with a variety of excellent properties and characteristics.

Thermal stability: Large-diameter quartz glass tubes have a small coefficient of thermal expansion and can withstand severe changes in temperature without cracking due to sudden changes in temperature.

Light transmittance: Quartz glass has good light transmittance across the entire wavelength band, with high transmittance.

Electrical insulation properties: The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, making it an excellent electrical insulation material. It also has good insulation properties even at high temperatures.

High temperature resistance and corrosion resistance: The softening point temperature of quartz glass is about 1730 ° C, which can be used for a long time at 1100 ° C, and the maximum temperature for a short time can reach 1450 ° C. Except for hydrofluoric acid, quartz glass hardly reacts chemically with other acids, and its acid resistance is 30 times that of ceramics and 150 times that of stainless steel.

Application field: Large diameter heating quartz glass tube is widely used in semiconductor electronics industry, solar photovoltaic industry, laboratory and other fields.

Heating principle: Quartz tube heating is a process of heat transfer. Quartz tube using a special process of opalescent quartz glass tube, with resistance composite material as a heater, opalescent quartz glass can absorb almost all the visible and near-infrared light radiated from the heating wire and convert it into far-infrared radiation.

Large diameter heated quartz glass tubes play an important role in many high-tech fields due to their unique physical and chemical properties.
