The quartz tube is processed without coating, and has stable radiance, no deformation at high temperature, no harmful radiation, no environmental pollution, high temperature resistance and high corrosion resistance, good chemical stability, small thermal inertia, fast thermal response speed and high thermal conversion efficiency.  The heating temperature can be selected by itself, the radiation performance does not deteriorate after long-term use, and the structure is reasonable and convenient to use.  Quartz tube is the only selective radiation far infrared heating element in China.  has wide application and strong applicability.  It can be widely used in heating and drying, solidification and dehydration of electromechanical, chemical, electronic textile, printing and dyeing, plastic, printing, grain, food processing, medical hygiene, leather and other heating equipment.  Quartz tube is especially suitable for medical and health, scientific research laboratory, environment requiring no pollution, corrosive heating occasions including acid and alkali, etc.

 Including quartz tubes of various specifications such as transparent, pearlescent, UV, ultraviolet sterilization, etc., with a diameter ranging from 2 mm to 180 mm, a wall thickness ranging from 0.5 mm to 8 mm, a continuous melting quartz tube 10 mm to 2000 mm long, a hydroxyl removing tube, an ultraviolet filtering tube, and an ozone-free tube.  The SiO _ 2 of ordinary continuous melting tube is above 99.6, with excellent geometric size, chemical stability, thermal stability, thermal denaturation and crystallization resistance, and optical transmittance above 90 %.  The hydroxyl group in the dehydroxylation tube is below 10 ppm, and after processing, the hydroxyl group can reach below 5 ppm.  Pearlescent tubes are new products of milky white tubes, with the surface of tubes like pearls, used in the manufacture of heating tubes, heating tubes and far infrared tubes.  The ultraviolet filter tube can filter out the ultraviolet rays of 190 - 320 nm wavelength harmful to human body in the ultraviolet spectrum band, and is suitable for the manufacture of environment-friendly light sources.  The ozone-free tube, in contrast to the ultraviolet filter tube, can transmit ultraviolet rays with a wavelength of about 253.7 nm and is widely used for sterilization of medical devices, water treatment, food hygiene, etc.  Shi Ying plate, Shi Ying sleeve, Shi Ying water jacket, Shi Ying plate, Shi Ying weight, Shi Ying ring, Shi Ying boat and various shaped quartz tubes are processed, and low ozone quartz tube ultraviolet germicidal lamps are produced.  The diameter of Shi Ying casing ranges from 8 mm to 120 mm, with round head, flat head and other shapes and flaring, flanging, sanding and other processing.  It has the characteristics of high temperature resistance, corrosion resistance, good light transmittance, moisture resistance, explosion resistance and the like, and is widely used in the processing of aquarium lamps, disinfection equipment, heating pipes, water treatment and other fields such as environmental protection, sanitation, chemical industry and the like.  Shi Ying water jacket is mainly used in printing and packaging processing industry - UV curing, which is a very reliable curing technology that can replace hot air dryers and other drying technologies and has been widely used in printing and packaging processing industry.  Quartz tube, Shi Ying tube.
