The working principle of the silica gel electric heater is that the non-metallic superconducting ion heat source generates terminal voltage when it is energized. Under the action of the electric field, the moving electrons and ions collide violently, and high-speed friction generates field-effect heat energy.
At present, Ag, Cu, and A1 have good properties of heating materials, and their specific resistances are 1.63, 1.694, and 2.67 respectively. These three kinds of materials can only conduct electricity and are excellent materials that do not generate heat. The non-metal super
The heating material has a specific resistance of 0.22, which is more than 7 times that of Ag, and is called a superconducting material. The addition of superconducting raw materials for the heating sheet greatly reduces the thickness of the heating layer of the non-metallic superconducting ion heat source sheet, reduces the unit cross-sectional area of the passing current, increases the number of electron impacts, and increases the temperature of the heating layer and reduces the heat capacity ratio. The field effect heating and heating up quickly are achieved, and the purpose of high efficiency and energy saving is realized.
The non-metallic superconducting ion heat source sheet heats uniformly, which changes the heating method of the linear structure of the resistance wire and the cylindrical structure of the quartz and carbon rods. It overcomes the shortcomings of the large heat capacity ratio and large thermal inertia of the heating element, and reduces the distance of the heat transfer meson. The temperature difference between the heating element and the heat conductor is reduced, and the heating temperature is consistent with the designed use temperature. Shorten the heating time and greatly reduce the heat loss.

Electrical properties, the click-through strength is 90-98KV/mm2, it is the dielectric constant and dielectric loss tangent that change very little in a wide temperature and frequency range. The dielectric constant is not only smaller than that of general organic materials, but also decreases with increasing temperature. It has the advantages of arc resistance and corona resistance. It is a raw material between organic and inorganic. It produces SiO2 self-reliance when burned at high temperatures.
