Abstract
The invention discloses a reworking method of a primer-coated part, and belongs to the technical field of aeronautical manufacturing. The reworking method adopts the technical scheme by comprising the following steps: dissolving a primer coating the surface of a part by using a Socostrip A0212 paint stripping agent; repeatedly coating the surface of the part with the paint stripping agent so as to take out the primer in micropores in the surface of the part; washing off the paint stripping agent attached to the surface of the part by deionized water; then, removing a membrane on the surface of the part by using an alkaline solution; washing off products of alkaline corrosion through an acid solution so as to obtain a part in a state that the surface can be reprocessed. Compared with a conventional method, the reworking method disclosed by the invention has the advantage that the primer can be removed more thorough. Compared with a mechanical method, the reworking method disclosed by the invention has the advantages that parts are not damaged, the shapes of the parts are not limited, and the degree of coarseness of the surfaces of parts is not influenced. Compared with a method for wiping off primer by an organic solvent, the reworking method disclosed by the invention has the advantages that the primer removing effect is more efficient; the reworking method is easy to operate; the membrane forming effect is better when surfaces are reprocessed.
Description
Technical field
The present invention's one is coated with primer part reworking method, belongs to aero-manufacturing technology field.
Background technology
This invention aims to provide a kind of reworking method being coated with primer part, in the past for the part being coated with primer, if there is problems such as the contaminated or primer in primer surface exceed the time limit, the mode of employing makes mechanically to be removed by primer or with an organic solvent wiped by the primer of piece surface.Making mechanically can injuring part matrix, and the part strict for dimensional requirement cannot adopt this kind of mode, has limitation; Use the primer of removal piece surface that butanone erasing primer can not be real, just the primer being attached to surface is wiped, and the primer in piece surface micropore cannot be wiped, surface treatment film forming when impact is done over again.
Summary of the invention
The object of invention: invent a kind of reworking method being coated with primer part, can remove the primer of piece surface coating, makes chemically to be removed totally by primer, avoids damaging substrate, is applicable to the various metal parts being coated with primer.
The technical scheme of invention: a kind of painting primer part reworking method, the method is used for the metal parts of surface coating primer, it is characterized in that, the method adopts following steps:
(1) use compressed air by clean for the primer removing surface of part;
(2) use brush to brush one deck Socostrip A0212 paint stripper on the surface at the primer of part, after parking 5 minutes, use brush to remove by the paint stripper of piece surface and by the primer dissolved;
(3) step (2) twice is repeated;
(4) the Socostrip A0212 paint stripper erasing using clean wiper to be adhered to by piece surface is clean;
(5) part is put into deionized water to soak 3 ~ 4 minutes, after 3 minutes, check piece surface moisture film continuity;
(6) part is immersed in alkaline solution carry out demoulding, occur that bubble is after 60 seconds from piece surface, soak part 3 ~ 4 minutes by deionized water;
(7) soak part after 1 minute with acid solution, then soak part 2 ~ 5 minutes by deionized water, then make part natural drying;
(8) again surface treatment is carried out to part, and at piece surface coating primer.
Advantage of the present invention: the painting primer part reworking method that the present invention uses removes primer more thoroughly compared with previous methods.Compared with mechanical means, method of the present invention not injuring part, not limit feature profile, on Part Surface Roughness without impact; Compared with the method for wiping primer with organic solvent, it is more effective that method of the present invention removes primer, and be easy to operation, during surface treatment, film-formation result is better again.
Detailed description of the invention
The primer that the present invention uses Socostrip A0212 paint stripper to be applied by piece surface dissolves, and being taken out of by the primer in piece surface micropore, being cleaned by the paint stripper being finally attached to piece surface with deionized water by repeatedly applying paint stripper.Then use alkaline solution to be removed by piece surface rete, then to be cleaned by the product of acid solution by caustic corrosion, part finally reaches can surface treatment state again.
