The new type of thin film heating sheet involves a heating sheet combined in series using ceramic heating element to solve the problems of existing technology that are easy to overheat and burn, high failure rate, and potential safety hazards; The upper and lower films and a metal heating sheet are clamped together, the upper and lower films are materials with high temperature resistance and insulation characteristics, and the metal heating sheet is twisted and wound, especially in the position of the two pole pieces of the metal heating sheet, or in any selected position of the metal heating sheet winding, combined with a ceramic heating element (PTC) in series, using the thermal resistance characteristics of the ceramic heating element, so that the film heating sheet reaches the set high temperature, because the ceramic heating element presents a high resistance and low current conduction state, Therefore, the effect of constant heat temperature can be obtained; The utility model is mainly used in the field of electric heating.
A new type of faceted heating sheet, which comprises a reinforcing sheet, an electric heating material and a substrate, the substrate has a large area, and the electric heating material is mixed with rubber, carbon black powder and conductive metal powder, the reinforcing sheet is laid with a layer of the electric heating material to form an electric heating sheet, the electric heating plate is attached to the substrate, and the conductive sheet body is fixed on the heating plate for connecting the power supply to form an electrode for electronic circuit. The surface heating sheet of the utility model has simple structure, convenient production, good strength and heating effect.
HTCC ceramic heating sheet is a high temperature co-fired ceramic heating sheet, is a use of tungsten, molybdenum, molybdenum manganese and other high melting point metal heating resistance slurry printed on 92~96% alumina cast ceramic green according to the requirements of heating circuit design, 4~8% sintering additives and then multi-layer superposition, at 1500~1600 °C high temperature co-firing into one, so as to have corrosion resistance, high temperature resistance, long life, high efficiency and energy saving, uniform temperature, good thermal conductivity, fast thermal compensation speed and other advantages, Moreover, it does not contain harmful substances such as lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ethers, and meets the environmental protection requirements of EU RoHS.
