Description
Technical field
A kind of method for quickly removing corrosion product with steel matrix the present invention relates to novel site.
Background technology
During equipment, the use of part, because the corrosiveness of environment often causes the local corrosion of steel matrix
Get rusty phenomenon, if local corrosion location not in time, is effectively cleared up and protected, equipment, part can be had a strong impact on
It is safe, long-acting to use.Therefore, it is necessary to the corrosion product of local corrosion location in equipment, the maintenance of part or rework process
It is removed, while needing to carry out supplement protection to cleaning position.
Corroding the live derusting method taken generally for steel matrix includes hand cleaning, chemical derusting and mechanic shot peening
(sand) etc..Hand cleaning is second-rate, and the rusty scale of deep layer is difficult complete removal, while the labor intensity of operating personnel is larger；Machine
Tool shot-peening (sand) can obtain excellent surface, but have certain equipment requirement, and labor intensity is big, and dust is more, it is necessary to complicated
Post processing, while the corrosion location for being unsuitable for for example requiring dust is safeguarded；And if the method for general chemistry derusting is used
Solution is soaked or sprayed, the trickling for easily occurring chemical solution, causes to handle that the surface solution residence time is short and shadow
Treatment effect is rung, corrosion product can not be removed completely.Simultaneously in descaling process chemical solution readily flow to it is other be not required to processing
Position, cause the anticaustic of steel matrix, easily method be deposited without particularly with the solution of complex-shaped part trickling
Remove easily, the safe handling to equipment, part causes a hidden trouble.
Therefore a kind of quick corrosion removal product method of new live steel matrix is invented, both can quickly and efficiently gone
One layer of corrosion-resistant finishes is formed except the corrosion product that steel matrix is generated, and at cleaning position, it is ensured that safeguarded, repaiied in local corrosion position
The need for reason；Method for maintaining will not have a negative impact to equipment, part；The features such as method for maintaining has simple, feasible simultaneously,
Ultimate guarantee equipment, part can be with long-acting, safe uses.
The content of the invention
The present invention quickly removes the method for corrosion product with steel matrix to steel equipment, part generation office using novel site
Portion's corrosion location carries out derusting and rust proof maintenance, can quickly and efficiently remove the local corrosion product of steel matrix, eliminate and remove again
Chemical reagent is for the adverse effect of the non-corrosion location of steel matrix during rust, and method is simple and easy to apply, and takes this method to exist
Can generate one layer in corrosion location while eliminating corrosion product has anticorrosion and the good protection of organic film adhesion
Layer, by applying the postprocessing working procedures such as corrosion inhibiter or organic coating to reach the purpose of derusting rust-proofing.
The inventive method includes following process：
(1) removal of the floating rust in steel matrix local corrosion position
Steel matrix local corrosion position is confirmed, by using friction tool, the floating of corrosion location of physically polishing
Rust, is polishing to corrosion location surface and exposes metal surface, and oil removing is carried out to corrosion surface using organic solvent；
(2) removal of steel matrix deep layer corrosion product
Surface coating derusting and rust proof chemical material after polishing, applied thickness is no less than 1mm, should kept after coating
0.5 hour~3 hours, after there occurs chemical reaction between derusting and rust proof chemical material and erosion, coated surfaces are carried out
Residue chemistry material is removed, and the chemical material of steel matrix surface residual is removed completely；
(3) the supplement protection after corrosion product is removed
Supplement protection should be carried out to removing the steel matrix surface after erosion, corrosion inhibiter or organic coating are coated in removal
Erosion portion faces, forming protection film layer prevents steel matrix from corroding.
Further, friction tool is metallic brush, scrub-brush, sand paper or emery wheel.
Further, described derusting and rust proof chemical material is derusting and rust proof chemical ointment, particularly steel derusting and rust proof
Learn ointment.
Further, step (3) post-etching thing also has residual, and step (2) and step (3) should be repeated.
Embodiment
The present invention is quickly gone mainly for the position of steel matrix surface local corrosion using a kind of novel site with steel matrix
Except the method for corrosion product, corrosion product is removed, while by this method one layer can be formed at local corrosion position
Antirust film layer, reaches the purpose of quick to local corrosion location, effective derusting and rust proof.Specific implementation is in the following ways：
(1) removal of the floating rust in steel matrix local corrosion position
The product rust and dirt on component corrosion surface are removed using instruments such as metallic brush, scrub-brush or sand paper, until corrosion portion
Metallic luster is exposed in position, with being soaked with the cotton yarn or cloth of the organic solvents such as gasoline, acetone or leaning solvent to the table after cleaning
Face oil removing, processing surface is dried in atmosphere after oil removing.
(2) removal of steel matrix deep layer corrosion product
The chemical ointment of derusting and rust proof is applied to the ready part in surface with brush or scraper, and keeps 0.5h~3h, it is thick
Degree is no less than 1mm.Ointment should be coated on all surfaces of the corrosion region of piece surface or part.Used ointment should not
Corrosiveness is produced to steel matrix surface, while its hydrogen embrittlement performance should meet requirement after steel matrix is contacted with ointment.Ointment with
Steel matrix should also form one layer after fully acting on steel matrix surface has corrosion resistance and the good protection of organic film adhesion
Layer.Illustrate ointment and the process of corrosion product interaction when surface color changes and (becomes pale green-white by rust)
It has been terminated that, ointment can be purged.It can be reprocessed when corrosion product is not completely removed with ointment.
The product that the ointment machin of residual interacts can be removed with hairbrush, scraper plate, cotton yarn or cloth etc., removal process should be careful
Arrange, it is to avoid residual ointment is scattered or is retained in equipment, part.After ointment is removed, flowing can be used to go depending on actual conditions
Ionized water cleaning parts surface is until cleared remaining ointment, it is possible to use speckle with gasoline, acetone or leaning solvent etc. organic
The cotton cleaning of solvent.It can in atmosphere spontaneously dry or be dried up with the compressed air of cleaning after Cleaning of Parts.
(3) the supplement protection after corrosion product is removed
Remove after corrosion product, further corrode to prevent from removing position, supplement protection should be carried out to the position as early as possible.Can
To be coated corrosion inhibiter or organic coating after corrosion removal product, corrosion inhibiter should select normal temperature rapid curing body with organic coating
System, while removing ointment and the time interval requirement of supplement protection：3h is not to be exceeded in structural steel；12h is not to be exceeded in stainless steel.
