Presently commercially available micarex, owing to area is big, product resistance is uneven, causes product surface non-uniform temperature, after work certain time, product general power decay about 20%, and life of product is not long, it is easy to damage and scrap.
To this, primarily now there is following patent in China:
Patent publication No.: CN103002608A, disclose a kind of mica electro-thermal film, this mica electro-thermal film is composite layered structure, centre is heat generating member, being close to heat generating member two sides is mica substrate, described heat generating member is the alloy foil sheet being etched with heating circuit, and described mica substrate is that Muscovitum crosses gummed paper, and described Electric radiant Heating Film is formed by high temperature adhesive and the compacting of high-temperature laminating technique by alloy foil sheet, mica substrate.This utility model mica electro-thermal film simple in construction, thermal conversion efficiency is high, uses the heating equipment that this mica electro-thermal film is made to meet the instructions for use of safety and comfort, environmental protection and energy saving.But, disclosed in this utility model, the heat generating member of mica electro-thermal film is close to mica substrate, have that unit cross-sectional area power density is big, surface temperature is high, differential expansion coefficient is big, yielding, work time have sound, have the place of line with heating function to cause the problems such as excessive the brought heating wire short circuit of Muscovitum differential expansion coefficient, sparking, too fast oxidation because temperature is significantly high in preparation.
Utility model content
For solving above-mentioned Problems existing, the purpose of this utility model is in that to provide a kind of high temperature resistant Electric radiant Heating Film of Muscovitum.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is: a kind of high temperature resistant Electric radiant Heating Film of Muscovitum, it is characterized in that, including: metal electrode and the first mica layer stacked gradually from bottom to top, the first heat conducting film, metal heating layer, the second heat conducting film, the second mica layer；Described first heat conducting film is evenly applied to described first mica layer upper surface；Described metal heating layer is arranged at described first heat conducting film upper surface；Described metal heating layer is evenly distributed with some electrical conductivity alloy bars；Described metal electrode electrically connects with metal heating layer；Described second heat conducting film is evenly applied to described metal heating layer upper surface；Described second mica layer is arranged at described second heat-conducting layer upper surface；Described first, second heat conducting film is mainly composed of carborundum, wherein mass fraction >=50% of carborundum.
Further, described electrical conductivity alloy bar is rustless steel, aluminum, pyrite, corronil, copper or other electric resistance alloys.
Separately, described first, second heat conducting film thickness is 0.08 ~ 0.2mm.
Separately have, bonding by high-temperature adhesives between described first mica layer, the first heat conducting film, metal heating layer, the second heat conducting film, the second mica layer.
Again, described metal heating layer thickness is 0.02 ~ 0.03mm.
Further, described metal heating layer both sides are equipped with metal current-carrying bar, described electrical conductivity alloy bar connects in addition in parallel by metal current-carrying bar.
The beneficial effects of the utility model are in that: increase heat-conducting layer, utilize the carborundum that heat conductivity is very big, rapidly the amount of localized heat that electrical conductivity alloy bar produces can be diffused into entirety；Thus solving that heater unit cross-sectional area power density is big, surface temperature is high, differential expansion coefficient is big, yielding, work time have sound, have the place of line with heating function to cause the problems such as excessive the brought heating wire short circuit of Muscovitum differential expansion coefficient, sparking, too fast oxidation because temperature is significantly high in preparation.
