What is the principle of ptc electric heating film?
The principle of the silica gel electric heating plate is that the thermistor heats up after being powered on, so that the resistance value enters the jump zone, and the PTC thermistor is heated at a constant temperature, and the surface temperature will be maintained. The temperature is only related to the temperature of the PTC thermistor and the applied voltage, and is basically independent of the ambient temperature.

Features of PTC heating film:
1. Cost-saving, long life, no need for special temperature controllers and thermal resistance thermocouples and other temperature sensors for temperature feedback to control the heating of the heater. Its temperature adjustment is based on its own material characteristics, so that this product has a great For the service life of other heaters. Rapid heating, automatic temperature control in case of fan failure, long service life
2. Safe, green and environmentally friendly, the heater body is designed to have a heating temperature of multiple levels below 200 degrees Celsius. In any case, the body does not redden and has a protective isolation layer. Any application does not require asbestos and other heat insulation materials to cool down. Rest assured that there is no problem of burns to the human body and fire.
3. Save electricity, compare electric heating tube and resistance wire heating products. It relies on the characteristics of the material itself and adjusts its own thermal power output according to the change of ambient temperature, so it can optimize the heater's power consumption to a minimum, and at the same time, it has high heating efficiency. The materials also greatly improve the efficiency of electric energy utilization.
