Let's talk about the working principle and precautions of electric heating tablets .
The direct resistance heating of the electric heating sheet manufacturer requires a special alloy material or non-metal material to make the heating element. The heat energy generated by the heating element is transmitted to the heated object through radiation, convection and conduction. Because the heated object and the heating element are divided into two parts, the type of the heated object is generally not restricted and the operation is simple.
Heater manufacturers use the high temperatures of arcing to heat objects. An arc is a 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 transpiration 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 melting of metals.
Because of the strong penetration ability of infrared rays, heating film manufacturers are easily absorbed by objects, and once they are absorbed by the object, they are immediately converted into thermal energy. The energy loss before and after infrared heating is small, the temperature is easy to control, and the heating quality is high. Therefore, the use of infrared heating has been developed. quickly.
