1. When using this type of electric heating device, it must be noted that the continuous operating temperature should be less than 240 °C, and the instantaneous temperature should not exceed 300 °C.
2. The electric heating device of the silicone heating sheet can work and be under pressure, that is, use an auxiliary pressure plate to make it close to the heated surface. At this time, the heat conduction is good, and the power density can reach 3W/cm2 when the working area temperature does not exceed 240℃.
3. The allowable working temperature is less than 150°C under the condition of paste-type 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 non-continuous conditions, the power density can reach 1.4 W/cm2.
5. The selection of working voltage is based on the principle of high power-high voltage, low power-low voltage, and special needs can be excluded.
