1. How to install the silicone electric heater? Can a DC power supply be used?
When using the silica gel heating sheet, choose a variety of methods such as double-sided adhesive paste, room temperature vulcanization, drilling positioning, etc. according to the actual site. Silicone heating elements cannot use DC power. The heating principle of silicone heating elements is that alternating current generates a vortex magnetic field in the silicone heating element. The vortex magnetic field generates eddy currents in the silicone heating element. The resistance of the silicone heating element is large. So the vortex current is converted. It is heat. If direct current is used, the silicone heating sheet will not have eddy current and cannot generate heat.
2. What is the difference between 110V and 220V ptc heating film? What about mixing?
The ptc heating element is a positive temperature coefficient device, and the resistance value increases greatly with the increase of temperature. If a 220V heating element is used on 110, its resistance increase is relatively small, and the current will be relatively large, but the heat generation may not increase a lot. . It is recommended to match.

3. How to assemble 5 PTC heating elements?
The 5-head PTC heating element should be assembled according to different power requirements. 1, 3, and 5 are one pole; 2, 4 is one pole, 1, 3, and 5 are combined together as one end; 2, 4 combined together is the other end , Access to 220V is full power.
4. Will the PTC electric heating chip explode?
There is a failure mode of PTC heating element called breakdown, and there will be blasting sound accompanied by strong light during breakdown. Under normal circumstances, the ptc heating element will have an external insulation structure, and there will be a small blasting sound when a breakdown occurs, no strong light can be seen, and it will not hurt people.
5. The advantages of various types of heating films are different, how to distinguish them?
(1) Safe heating sheet-usb heating sheet, polyester heating sheet
The surface is safe and non-charged, with good insulation performance, no open flame, and safe to use
(2) Soft heating sheet——silica gel heating sheet
It has good flexibility and can be in close contact with the heated object. Because it is flexible, it is easier to be close to the heating body, and the shape can be changed according to the requirements to design the heating, so that the heat can be transferred to any place needed
(3) Healthy heating sheet-mica heating sheet, polyester heating sheet
When the component is working, the infrared radiation is strong, and its far-infrared wavelength is 2-15um, which is beneficial to human health
(4) The heating piece with the largest heat shock-arc heating piece
In addition to the advantages of rapid heating of flat heating elements, high thermal efficiency, uniform heating, no open flame, safety and environmental protection, and long service life, it has superb flexural strength and thermal shock resistance, and can closely fit various circular surfaces. Obvious features such as enhanced thermal efficiency.
