Abstract
The invention relates to the field of the manufacturing of high-voltage electrotechnical porcelain, and discloses a method for separating an organic bonding porcelain bushing without damage, which comprises the following steps of: putting the organic bonding porcelain bushing into a kiln car in an industrial kiln; after the temperature is raised to 50 DEG C, raising the temperature of the organic bonding porcelain bushing to 100 DEG C, 150 DEG C, 200 DEG C and 500 DEG C sequentially according to 10 DEG C/hour, 15 DEG C/hour, 25 DEG C/hour and 35 DEG C/hour, and preserving the heat at 500 DEG C for 1 hour; reducing the temperature to 300 DEG C and 150 DEG C sequentially according to 25 DEG C/hour and 20 DEG C/hour; and finally, cooling naturally with the kiln.
Description
Technical field
The present invention relates to high tension insulator and make field, particularly a kind of harmless separation method of organic bonding porcelain bushing.
Background technology
In the high tension insulator process of producing product, the electric insulators of voltage levels generally adopts sectional forming, and is then that each section porcelain spare is as a whole with the bonding one-tenth of organic adhesion agent.For check organic bonding porcelain bushing interface bonding quality, need carry out the interface withstand voltage test.If the interface withstand voltage test is defective, general processing method is: docking port is withstand voltage underproof insulator, heat at interface one side distance interface 200～300mm place winding resistance wire and energising, when being heated to uniform temperature, throw cold water at the heating position again, utilize the method for chilling to make insulator from the fracture of heating position.The result who does like this keeps a joint insulator, scraps another joint insulator.And then the insulator that remains is carried out interface grind, select another joint insulator to carry out organic bonding again again.Do like this and not only cause waste, grind workload but also increased the insulator interface.
Summary of the invention
The object of the present invention is to provide a kind of harmless separation method of organic bonding porcelain bushing,, make its forfeiture adhesive strength, realize the harmless separation of insulator by heating and decomposition, carbonization organic adhesion agent.
In order to achieve the above object, the present invention is achieved by the following technical solutions.
A kind of harmless separation method of organic bonding porcelain bushing, it is characterized in that, described harmless separation method may further comprise the steps: on the kiln car in the Industrial Stoves of at first organic bonding porcelain bushing being packed into, after being warmed up to 50 ℃, being warmed up to 100 ℃, 15 ℃/h according to 10 ℃/h successively is warmed up to 150 ℃, 25 ℃/h and is warmed up to 200 ℃, 35 ℃/h and is warmed up to 500 ℃, 500 ℃ of insulation 1h; Then, cool to 300 ℃, 20 ℃/h according to 25 ℃/h successively and cool to 150 ℃; At last, with the stove natural cooling.
Technique scheme is applicable to that more the organic adhesive that described organic bonding porcelain bushing uses is: the organic adhesive of the cold curing of being made up of E-51 epoxy resin, diethylenetriamine, aminopropyl triethoxysilane, aerosil, wollastonite in powder; Or the organic adhesive that described organic bonding porcelain bushing uses is: by E-51 epoxy resin, right-that MDA, aminopropyl triethoxysilane, liquid polysulfide rubber, aerosil, silicon powder are formed the hot setting organic adhesive.
The inventor is through the organic adhesion agent performance is studied, and when organic adhesive was heated to 500 ℃ according to certain heating rate, the organic adhesion agent adhesive began to decompose, carbonization, the forfeiture adhesive strength, and can not produce infringement to insulator.Therefore, the present invention adopts Industrial Stoves to heat to organic bonding porcelain bushing, and decomposition, carbonization organic adhesion agent make its forfeiture adhesive strength, and the realization insulator is harmless to be separated.
