Abstract
The method includes steps: (1) carrying out surface cleaning for heating wire to be treated to remove oil stain and foreign bodies on surface; (2) carrying out drying for heating wire with surface cleaned to remove moisture on surface; (3) carrying out oxidation treatment in high pressure oxidation oven in high temperature for drying treated heating wire: under condition of pure oxygen in pressure 0.5-0.7kg .f/cm2 at 950-1200deg.C, oxidizing for1.5h minus or plus 5', then stopping process and cooling till to normal temperature; (4) moving the treated heating wire out of furnace. Advantages are: even insulating layer, high insurability, long service life and no variety of the heating wire in all-weather. Moreover, no poison gas is generated in treating procedure.
Description
Technical field
The present invention relates to a kind of electrothermic wire insulation treating method.
Background technology
Electrothermic wire insulation commonly used is in the market handled belong at its surface-coated coatings more, carries out chemical oxidation treatment (liquid state) again.The major defect of this processing method is: easily discharge little poisonous gas behind the electric heating, the mould rainy day can produce mildew, and useful life is not long.
Summary of the invention
Technical problem to be solved by this invention provides and a kind ofly can improve electrothermic wire insulation performance and useful life, and the electrothermic wire insulation treating method that no any toxic gas produces in processing procedure.
For solving the problems of the technologies described above, electrothermic wire insulation treating method of the present invention comprises:
(1), pending heating wire is carried out removing surface, removal surface and oil contaminant, foreign material;
(2), the heating wire of removing surface is dried the removal surface moisture;
(3), will dry the heating wire of handling and carry out oxidation processes in the HTHP oxidation furnace: passing to pressure under 950-1200 ℃ temperature is 0.5-0.7kg.f/cm
2Purity oxygen, through after 1.5h ± 5 ' oxidation, stop heating, until being cooled to normal temperature;
(4), come out of the stove.
Adopt the electrothermic wire insulation layer after the insulation processing of the present invention even, insulation property are strong, round-the-clock no change, and long service life, and nonhazardous gas produces in processing procedure.
Embodiment
(1), with pending heating wire ultrasonic waves for cleaning, remove surface and oil contaminant, foreign material;
(2), the heating wire of removing surface is placed in the baking oven dries, remove surface moisture;
(4), will dry the heating wire of handling and carry out oxidation processes in the HTHP oxidation furnace: passing to pressure under 1200 ℃ temperature is 0.6kg.f/cm
2Purity oxygen, through after 1.5h ± 5 ' oxidation, stop heating, until being cooled to normal temperature;
(4), come out of the stove vanning.
Claims (3)
1, a kind of electrothermic wire insulation treating method comprises:
(1), pending heating wire is carried out removing surface, removal surface and oil contaminant, foreign material;
(2), the heating wire of removing surface is dried the removal surface moisture;
It is characterized in that also comprising:
(3), will dry the heating wire of handling and carry out oxidation processes in the HTHP oxidation furnace: passing to pressure under 950-1200 ℃ temperature is 0.5-0.7kg.f/cm
2Purity oxygen, through after 1.5h ± 5 ' oxidation, stop heating, until being cooled to normal temperature;
(4), come out of the stove.
2, electrothermic wire insulation treating method according to claim 1 is characterized in that the temperature in the step (3) is 1200 ℃.
3, electrothermic wire insulation treating method according to claim 1 and 2 is characterized in that the pressure in the step (3) is 0.6kg.f/cm
