Description
Technical field
The present invention relates to a kind of coating process of bellows component used for high-voltage switch, belong to application techniques field.
Background technique
Corrugated stainless steel tubing assembly is the important spare part for guaranteeing high-voltage switch gear installation accuracy, it, which is mainly used for adjusting, opens
Close the distance between each separate unit.High-voltage switch gear air-tightness well whether with its later period can trouble free service count for much, institute
To be all to carry out coating again after first passing through installation and debugging for corrugated stainless steel tubing assembling.Installation process has used a large amount of standard
Part such as screw thread, nut, gasket etc. just easily introduces lubricating oil, lubricating grease etc. in the gap of component.In order to guarantee that coating quality is full
Sufficient requirement, has to thoroughly remove that clean there are the greases in gap in coating process.
At present there are mainly two types of the cleaning ways of bellows assembly: first is that it is molten that bellows assembly is integrally immersed weak base
Degreasing is carried out in liquid；Second is that being cleaned using organic solvent such as gasoline, ethyl alcohol or acetone.Due to space pole between standard component
Its is limited, is easy the oil lubrication rouge brought into residual assembling process, no matter de- with weak caustic solution or Solvent degreasing
Rouge, solution are all not easy to flow into or out gap, and the grease remained on inside gap is not easy to be carried out, oily after the washing
Rouge, which still remains in each assembling gap of bellows assembly, to be not easy to be found.
Residual greasy dirt in bellows gap, carries out coating in this situation, and greasy dirt is closed in coating in the following, and with oil
Dirt is slowly outer to drop down and etching resist, and switch active time is increasingly longer, and the reduction of regional area coating binding force has ultimately caused painting
Layer is from regional area premature degradation.So switch, after putting into operation, coating integral status is although keep very well, such as bellows
The regional area of coated article will start to gradually appear peeling, foaming phenomena, then feed through to bulk zone, affect switch
Whole anticorrosion ability, coating caused by problems, which is overhauled, causes great economic loss to enterprise.
Summary of the invention
The purpose of the present invention is to provide a kind of coating process of bellows component used for high-voltage switch.This method can be improved
The cleaning quality of bellows component improves the binding force of paint film.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of coating process of bellows component used for high-voltage switch, includes the following steps:
1) bellows component after cleaning is toasted into 12-18min at 45-55 DEG C；
2) it polishes, cleaning；
3) bellows component after cleaning in step 2) is toasted into 12-18min at 45-55 DEG C；
4) the bellows component surface spray-applied primer into step 3) after baking, then 30- is toasted at 80-100 DEG C
40min forms prime coat；
5) the bellows component surface spray paint into step 4) after baking；
6) bellows component after spray paint is toasted at 80-100 DEG C 30-40min, forms top coat layer.
Carrying out emphasis again by the cleaning of above-mentioned coating process, baking, locally cleaning and baking can be with thorough cleaning components
Greasy dirt at gap makes it volatilize or carbonization, the coating product qualification rate obtained by this method greatly improves, coating adhesive force
Reach 0-1 grades, ensure that the safety military service and the safe operation of power grid of high-voltage switch gear.
Above-mentioned steps 1) and step 2) described in cleaning be to be cleaned with gasoline.It is cleaned, is utilized using gasoline
Its volatile property, it is ensured that gasoline will not pollute components.
Above-mentioned steps 4) described in spray-applied primer when spray pressure be 0.3-0.4MPa.The pressure value of spray painting is controlled in 0.3-
When 0.4MPa, uniformly, surface is smooth for paint film spraying, and spray painting effect is best.
Above-mentioned steps 4) described in spray-applied primer when continuous spray twice.To bellows component spraying, priming paint makes ripple twice
Pipe lacquer painting is unlikely to too thick or too thin, and lacquer painting and the adhesion effect of bellows surface can be made to reach best.
Above-mentioned steps 4) described in prime coat with a thickness of 30 μm.Prime coat is with a thickness of can be to avoid paint film too at 30 μm
It is thin, it works long hours and easily corrodes, while the problem of being easy to fall off can be caused again to avoid priming paint is too thick.
Above-mentioned steps 5) described in spray paint when spray pressure be 0.3-0.4MPa.The pressure value of spray painting is controlled in 0.3-
When 0.4MPa, spray painting effect is best.
Above-mentioned steps 5) described in spray paint when continuous spray twice.Spraying twice of finishing coat to bellows component makes ripple
Pipe lacquer painting be unlikely to it is too thick or too thin and caused by corrode or the problem that falls off.
Above-mentioned steps 6) described in top coat layer with a thickness of 70 μm.The thickness control of top coat layer is wear-resisting at 70 μm
Property, salt tolerant, alkali resistance are preferable, and the adhesive force of top coat layer and priming paint is also preferable, not easy to foaming.
