Product introduction
The typical structure of the Cartridge Heater (the most popular structure) is the same as that of the pencil heater. It is generally composed of five parts: an insulator, a sealing material, an Mgo rod, a filler, a heating resistance wire NiCr8020, a SUS304 protection tube, and a terminal pin. The spiral electric heating resistance wire and the lead-out wire are located in the center of the metal sheathed tubes. The manufacturing process is to insert the spiral electric heating wire into the seamless steel pipe, and the gap is evenly filled with the insulation by the tube Mgo filling machine. A thermally conductive oxidizing medium such as crystalline magnesium oxide powder (also available in alumina or clean quartz sand). Then, the tube diameter is reduced by a tube shrinking machine to make the oxide medium dense (density reaches 3.3 g/cm3 or more), and the heating wire is insulated from the air, and the center position does not shift and touches the tube wall. such. The calorific value per unit area can be increased by a factor of ten. The service life can also be increased to more than 10 years. Compared with the same large heat electric heating element, the tubular electric heating tube can save 5% of the electrothermal material, and the thermal efficiency can reach more than 90%.
