Many people don’t know what kind of electric heating film is. In fact, many products in our lives now have electric heating film. The electric heating film is a kind of film that is energized and heats up. It is directly made on the electric heating during the production process. On the insulated surface of the appliance, it has extensive contact with the heater. Achieve high thermal efficiency,
Second: the temperature of the heating film itself is only a few tens of degrees higher than the liquid, there is no open flame, and the heating film takes up almost no space. Because the temperature is not very high, it is very convenient for heat preservation and heat insulation, so that the weight of the appliance is reduced a lot;
Third: The heating capacity of the electric heating film is small, and the heat source is turned on and off quickly; the electric heating film itself is transparent, if attached to a transparent substrate, the entire appliance can be made transparent; the film also has water resistance, acid resistance, alkali resistance and The advantage of high mechanical strength.
So such a good product is now used by many electrical products. This is also a manifestation of current technological progress
