The following heating film manufacturers will tell you the operation process of silica gel electric heating film:
1. When using this type of electric heating device, it must be noted that its continuous operating temperature should be less than 240°C, and the instantaneous temperature should not exceed 300°C.
2. The heater can work under pressure, that is, the auxiliary pressure plate is used to make it close to the heated surface. At this time, the heat conduction is better, and the power density can reach 3W/cm2 when the temperature of the working area does not exceed 240°C.

3. The allowable working temperature is less than 150°C in the case of stick-on installation.
4. In the case of dry burning in the air, the power density should be less than 1 W/cm2 due to the temperature resistance of the material; in the non-continuous working condition, the power density can reach 1.4 W/cm2.
5. The working voltage selection is based on the principle of high power-high voltage and low power-low voltage, and special needs can be listed.
Installation Precautions
1. The structure of the electric heater itself is not waterproof, so please do not come in contact with oil, water, or plastic particles during use to prevent electric leakage.
2. When using, the electric heating sheet must be closely attached to the heated body. The surface of the heated object should be flat and complete, and the uneven surface area should not be used for heating, otherwise it should be explained in advance.
3. After the electric heater is used, it should not produce charred black color on the heating surface, because this phenomenon indicates that the heat generation and heat absorption have not reached a balance.
4. When heating used electric heaters, avoid disassembly and assembly that will cause the heating wire to break, which will affect the operating life.
If there is a special, high-temperature place for use, it needs to be explained in advance to design a suitable heating element.
