The quartz heating tube does not use paint, has stable emissivity, no deformation at high temperature, no harmful radiation, no environmental pollution, high temperature resistance, high corrosion resistance, good chemical stability, small thermal inertia, fast thermal response, and high heat conversion efficiency. The heating temperature can be selected by itself, the radiation performance is not degraded for long-term use, and the structure is reasonable and convenient to use. Quartz heating tube is the only selective infrared radiation heating element in China. Wide range of uses and strong applicability. It can be widely used in mechanical, chemical, electronic textile, printing and dyeing, plastics, printing, food, food processing, medical hygiene, leather and other heating and drying, solidification and dehydration and heating equipment of various drying tunnels, drying rooms and ovens. Quartz heating tube is especially suitable for medical and health, scientific research laboratories, non-polluting environment, and corrosive heating occasions such as acid and alkali.
