The purpose of this utility model is for the ceramic heating pipe processing difficulties that overcomes prior art, the shortcoming that lack useful life, and a kind of ceramic heating is provided.
The purpose of this utility model can reach by taking following measure: ceramic heating, its design feature is: be made of ceramic matrix, conductive heating layer and insulating barrier, conductive heating layer is close on the outer surface of ceramic matrix, described insulating barrier is close to the outer surface of conductive heating layer, and the two ends of ceramic heating are provided with the metal connection post that contacts with conductive heating layer.
The purpose of this utility model can also reach by taking following measure:
Conductive heating layer is made of ceramic size, metal nickel powder, hafnium metal powfer and trace element, described ceramic size, metal nickel powder, hafnium metal powfer and trace element are mixed into mixed slurry by a certain percentage, and be coated in equably on the outer surface of ceramic matrix, form through low temperature drying, high temperature sintering.
It is earthenware that ceramic matrix is tubular, forms conductive heating layer on its surface, and the outer surface of described conductive heating layer forms a layer insulating again, and two ends are provided with the metal connection post that contacts with conductive heating layer, constitute the ceramic heating pipe.
It is ceramic wafer that ceramic matrix is sheet shape, forms conductive heating layer at its surperficial single face, and the outer surface of described conductive heating layer forms a layer insulating again, and two ends are provided with the metal lead wire that contacts with conductive heating layer, forms the ceramic heating plate of single face heating.
It is ceramic wafer that ceramic matrix is sheet shape, and at the two-sided formation conductive heating layer on its surface, the outer surface of described conductive heating layer forms a layer insulating again, and two ends are provided with the metal lead wire that contacts with conductive heating layer, forms the ceramic heating plate of two-sided heating.
Compared with prior art, the utlity model has following outstanding advantage:
1. form by the outer surface sintering that the slurry with conduction, heating function spreads upon ceramic matrix owing to conductive heating layer, therefore, enough requirements according to caloric value, adjust the weight ratio of the various conductive exothermal materials that constitute conductive heating layer arbitrarily, can be by adjusting the width and the thickness of conductive heating layer arbitrarily, to adjust its withstand voltage and power.
2. owing to be directly heating, far-infrared radiation of surface, therefore, thermal response is fast, the heat efficiency is high, does not have deposition heat.
3. because conductive heating layer is that composite material is made, the insulation property height, conduct electricity very well, conduction and heating surface area are big, so withstand voltage properties is strong, high temperature resistant, electromagnetic-radiation-free.
4. form through 1300 celsius temperature sintering owing to conductive heating layer, so antioxygenic property is good, long-term use can not chapped long service life.
5. the resistance of conductive heating layer has good positive temperature characterisitic (being PTC), and dissipation power has negative temperature characteristic (being NTC), so temperature stability is good.
6. because conductive heating layer is to form at the outer surface of conducting base, therefore, accomplish the surfacing, smooth of conductive heating layer easily, thickness is even, use in that high temperature (can reach more than 700 degrees centigrade) is long-term, and processing is simple.
