Heating pad is specialized in electrical energy into heat sheet electrical components, due to its cheap, easy to use, easy to install, no pollution, is widely used in a variety of heating occasions, the production of electric heating element manufacturers and brands also have a lot. The service life of the heating element is very long, the general design service life of more than 5000 hours, some far-infrared radiation heating element, can have a life of 5 heating season.
Heating piece into the electric heating element, and in the gap part of the tightly filled with good heat resistance, thermal conductivity and insulation of the crystalline magnesium oxide powder, after other processes. It has a simple structure, high mechanical strength, high thermal efficiency, safety and reliability, easy installation, 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.
