Embodiment
Below in conjunction with accompanying drawing ceramic electrothermal film heating pipe of the present invention and manufacture method are described in detail.
As shown in the figure, ceramic electrothermal film heating pipe of the present invention comprises earthenware 1, at earthenware 1 inwall Electric radiant Heating Film 2 is set.The present invention leaves the insulating regions more than the 2mm by taking the high temperature gas-phase deposition with the inwall of Electric radiant Heating Film 2 spraying platings at earthenware 1 at the two ends of earthenware 1 inwall.At the two ends of Electric radiant Heating Film 2 coating silver coating 5,5 places are provided with electrode 6 at silver coating, and lead-in wire 4 is connected with electrode 6, and what the electrode in the present embodiment adopted is the adjustable pushing out ring of diameter 3, and pushing out ring 3 is supported and fixed on silver-colored 5 places of starching with electrode 6.
The manufacture method of ceramic electrothermal film heating pipe of the present invention may further comprise the steps:
(1) earthenware is placed in the heating furnace, when furnace temperature reaches 440 ℃-560 ℃, the liquid medicine of making Electric radiant Heating Film is sprayed in the stove with vaporific, close fire door;
(2) after the earthenware that will reach the plated film of requirement power takes out cooling, at the two ends of Electric radiant Heating Film brushing silver slurry, treat silver slurry drying after, place in the heating furnace;
(3) sintering temperature of starching according to the difference control silver of silver slurry after the silver slurry is sintered to one with Electric radiant Heating Film, reaches specification requirement, is taken out in stove;
(4) in pipe, electrode is fixed in silver-colored slurry place, is connected with electrode with lead-in wire with pushing out ring.
The liquid medicine that will make Electric radiant Heating Film described in the step (1) sprays in the stove to repeatedly with vaporific.Liquid medicine in the step (1) is main for contained silver or non-silver oxide or halide by tin, antimony, molybdenum, zinc, chromium, iron, manganese, aluminium, copper, nickel, silicon, phosphorus, boron, fluorine, carbon etc., to mix the liquid medicine that solvent, additive are the inorganic conductive filmogen of assisting.Silver slurry in step (2) and (3) is meant based on the silver-colored alloy solvent with extremely strong conductivity, behind high temperature sintering, can become one with Electric radiant Heating Film, and because of the alloying component difference, fusing point is different naturally, and sintering temperature is also different; The difference of silver slurry is meant the fusing point difference of different silver slurries.
