Abstract
A kind of primer part reworking method that applies of the invention belongs to aero-manufacturing technology field.The technical scheme of use is that the primer for being coated piece surface using Socostrip A0212 paint strippers is dissolved, and is taken out of the primer in piece surface micropore by coating paint stripper repeatedly, is cleaned with the paint stripper that deionized water will be eventually adhering to piece surface.Then piece surface film layer is removed using alkaline solution, then is cleaned the product of caustic corrosion by acid solution, part is finally reached can surface treatment state again.It is an advantage of the invention that than ever method compared to more thoroughly removing primer, compared with mechanical means, the method for the present invention not injuring part, not limit feature profile, on Part Surface Roughness without influence；With organic solvent erasing primer method compared with, the method for the present invention remove primer it is more efficient, it is easy to operate, again be surface-treated when film-formation result more preferably.
Description
Technical field
A kind of painting primer part reworking method of the invention, belongs to aero-manufacturing technology field.
Background technology
The invention aims to provide a kind of reworking method for applying primer part, in the past for being coated with the part of primer, if
The problems such as primer surface is contaminated or primer exceeds the time limit occur, removed primer using mechanical system or using having by the way of
Machine solvent wipes the primer of piece surface.Can injuring part matrix, the part strict for size requirement using mechanical system
This kind of mode cannot be used, with limitation；The primer of the removal piece surface that primer can not be real is wiped using butanone, only
It is that the primer that will be attached to surface is wiped, and the primer in piece surface micropore cannot be wiped, influence is surface-treated into when doing over again
Film.
The content of the invention
The purpose of invention：A kind of reworking method for applying primer part of invention, can remove the primer of piece surface coating, make
Chemically primer is removed clean, it is to avoid damaging substrate, it is adaptable to the various metal parts for being coated with primer.
The technical scheme of invention：One kind applies primer part reworking method, and the method is used for the metal zero that surface coats primer
Part, it is characterised in that the method uses following steps：
(1) it is using compressed air that the primer removing surface of part is clean；
(2) one layer of Socostrip A0212 paint stripper is brushed on the primer surface of part using brush, is parked 5 minutes
Afterwards, the paint stripper of piece surface and the primer being dissolved are removed using brush；
(3) repeat step (2) is twice；
(4) the Socostrip A0212 paint strippers for being adhered to piece surface using clean wiper wipe clean；
(5) part is put into deionized water and is soaked 3~4 minutes, piece surface moisture film continuity is checked after 3 minutes；
(6) immersing in alkaline solution part carries out demoulding, after there is bubble 60 seconds from piece surface, is soaked with deionized water
Bubble part 3~4 minutes；
(7) after soaking part 1 minute with acid solution, then part is soaked 2~5 minutes with deionized water, then makes part
Spontaneously dry；
(8) part is surface-treated again, and primer is coated in piece surface.
Advantages of the present invention：The painting primer part reworking method that the present invention is used is more thoroughly clear compared with previous methods
Except primer.Compared with mechanical means, the method for the present invention not injuring part, not limit feature profile, to Part Surface Roughness
Without influence；Compared with the method for organic solvent erasing primer, it is more efficient that the method for the present invention removes primer, it is easy to operates, weight
Film-formation result is more preferably during new surface treatment.
Specific embodiment
The present invention is dissolved using the primer that Socostrip A0212 paint strippers coat piece surface, by coating repeatedly
Paint stripper takes the primer in piece surface micropore out of, is cleaned with the paint stripper that deionized water will be eventually adhering to piece surface.
Then piece surface film layer is removed using alkaline solution, then is cleaned the product of caustic corrosion by acid solution, part is final
Reaching can surface treatment state again.
Embodiment 1
The method uses following steps：
(1) part carries out chromic acid anodizing and coats primer.
(2) dust of primer surface attachment of part etc. is cleaned out using clean, dry compressed air；
(3) one layer of Socostrip A0212 paint stripper is brushed on the primer surface of part using brush, is parked 5 minutes
Afterwards, the paint stripper of piece surface and the primer being dissolved are removed using brush；
(4) repeat step (3) is twice；
(5) the Socostrip A0212 paint strippers for being adhered to piece surface using clean wiper wipe clean；
(6) part is put into deionized water and is soaked 3~4 minutes, piece surface moisture film continuity is checked after 3 minutes；
(7) immersing part carries out demoulding in alkaline solution, solution composition is the NaOH solution of 80-120g/l, from part
After surface bubble occurs 60 seconds, part is soaked 3~4 minutes with deionized water；
(8) after soaking part 1 minute with acid solution, then part is soaked 2~5 minutes with deionized water, then makes part
Spontaneously dry；
(9) chromic acid anodizing treatment is carried out to part again, and primer is coated in piece surface.
Embodiment 2
The method uses following steps：
(1) part carries out phosphoric acid and coats primer.
(2) dust of primer surface attachment of part etc. is cleaned out using clean, dry compressed air；
(3) one layer of Socostrip A0212 paint stripper is brushed on the primer surface of part using brush, is parked 5 minutes
Afterwards, the paint stripper of piece surface and the primer being dissolved are removed using brush；
(4) repeat step (3) is twice；
(5) the Socostrip A0212 paint strippers for being adhered to piece surface using clean wiper wipe clean；
(6) part is put into deionized water and is soaked 3~4 minutes, piece surface moisture film continuity is checked after 3 minutes；
(7) immersing part carries out demoulding in alkaline solution, solution composition is the NaOH solution of 80-120g/l, from part
After surface bubble occurs 60 seconds, part is soaked 3~4 minutes with deionized water；
(8) after soaking part 1 minute with acid solution, then part is soaked 2~5 minutes with deionized water, then makes part
Spontaneously dry；
(9) phosphoric acid treatment is carried out to part again, and primer is coated in piece surface.
