Discussion on the principle of quartz glass tube heater
The far-infrared heating tube is made of opalescent quartz glass tube processed by special process, and is equipped with resistance composite material as the heater. Because opalescent quartz glass can absorb almost all visible and near-infrared light radiated by the electric heating wire.
The far-infrared heating tube is made of opalescent quartz glass tube processed by special process, and is equipped with resistance composite material as the heater. Because opalescent quartz glass can absorb almost all visible and near-infrared light from the electric heating wire, and can convert it into far-infrared radiation. However, the current industrial infrared heating tube has basically eliminated the opalescent quartz tube. Because of its brittle material properties, it cannot form a long opalescent heating tube. And milky white has shading effect, which prevents its heat. Because of its high wall temperature, it is only suitable for near-infrared heating.
The technical features of quartz glass tube: (1) No far infrared coating is required, the spectral radiation matching and absorption characteristics are good, the radiation performance does not degenerate after long-term use, and the electrothermal conversion efficiency is high. It can save about 30% energy than ordinary heating elements. (2) High working temperature, wide selection range. Among them, the ceramic cap packaging type has a high temperature resistance of 800. (3) Fast temperature rise, small thermal inertia, high temperature resistance, corrosion resistance, good thermochemical stability, long service life and high insulation strength. (4) Non-polluting, it is a clean heater, which meets the requirements of modern production with high rhythm and high quality, and is suitable for household appliances with high sanitary requirements. (5) The design, manufacture and installation are very convenient, economical and safe.
