Below, the editor of the heater manufacturer will tell you the working principle and precautions of the electric heater.
The direct resistance heating of the electric heating chip manufacturer needs to make heating elements from special alloy materials or non-metallic materials. The heat generated by the heating elements is transmitted to the object to be heated through methods such as radiation, convection and conduction. Because the heated object and the heating element are divided into two parts, the variety of the heated object is generally not restricted, and the operation is simple.

The heater manufacturer uses the high temperature generated by the arc to heat the object. Arc is the phenomenon of gas discharge between two electrodes. The voltage of the arc is not high but the current is very large. Its strong current is maintained by many ions evaporated on the electrode, so the arc is easily affected by the surrounding magnetic field. When an arc is formed between the electrodes, the temperature of the arc column can reach 3000-6000K, which is suitable for high-temperature smelting of metals.
Because of the strong penetrating ability of infrared rays, heating film manufacturers are easy to be absorbed by objects, and once absorbed by objects, they are immediately converted into heat energy; the energy loss before and after infrared heating is small, the temperature is easy to control, and the heating quality is high. Therefore, infrared heating is used soon.
