Heating element is a sheet-shaped electrical component that converts electric energy into heat energy. Because of its low price, convenient operation, convenient installation and no pollution, it is widely used in various heating occasions. There are also many manufacturers and brands producing electric heating elements. The service life of heating elements is very long. Generally, the planned service life is more than 5000 hours. Some far-infrared radiation heating elements can have a service life of five heating seasons. The heating element is put into the heating element, and the gap is tightly filled with crystalline magnesium oxide powder with excellent heat resistance, thermal conductivity and insulation, and then processed by other processes. It has the characteristics of simple structure, high mechanical strength, high thermal efficiency, safety and reliability, simple device, long service life and so on. It is widely used in various nitrate tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying ovens, hot pressing molds and other devices. According to the function and material, the heating pieces can be divided into USB heating pieces, silicone heating pieces (silicone rubber heating pieces), mica heating pieces, MCH heating pieces, ceramic heating pieces, silicon guide heating pieces, soft carbon crystal heating pieces, pet heating film polyester heating pieces, aluminum foil heating pieces, cushion heating pieces, new planar heating pieces, new film heating pieces, etc.
