Description
Technical field
It derusts field the invention belongs to metal surface, and in particular to a kind of process except oxidation on metal surface skin.
Background technique
Metal through various working processes or storage for a long time, in use process, surface will appear one layer of oxide skin or
Evidence of oxide substantially reduces its corrosion resistance, not only influences beautiful and the later period processing, but also influence part uses the longevity
Life.Therefore, it is necessary to this layer of oxide skin or evidence of oxide of metal surface be removed clean.Removal oxidation on metal surface skin at present
Method mainly have a chemical method and physical method two major classes, but their there are techniques cumbersome, long flow paths, at high cost, energy consumption
Greatly, the disadvantages of pollution is heavy, work situation is poor.The present invention successfully invented it is a kind of it is low in cost, pollution is small, derusting is clean, technique
A kind of process except oxidation on metal surface skin being simple and convenient to operate.
Summary of the invention
In order to overcome the problems, such as the above-mentioned prior art, improve the shortcomings that its process, it is an object of the invention to one kind
Except the process of oxidation on metal surface skin.Derusting process of the invention, with low in cost, pollution is small, derusting is clean, technique
The advantages that being simple and convenient to operate.
In order to achieve the above objectives, a kind of the technical solution used in the present invention are as follows: technique side except oxidation on metal surface skin
Method, comprising:
Mixed liquor 1: water, concentrated nitric acid, concentrated hydrochloric acid, zinc chloride, citric acid ratio be 80 ~ 100ml:10 ~ 20ml:15 ~
35ml:10 ~ 20g:3 ~ 6g；

The mixture of starch and cleanser, the proportionate relationship of the starch and cleanser are as follows: 1:0.5 ~ 1.
The concentrated nitric acid, concentrated hydrochloric acid, the concentrated sulfuric acid, concentrated phosphoric acid etc. use commercially available concentrated nitric acid, commercially available concentrated hydrochloric acid, commercially available dense sulphur
Acid and commercially available phosphoric acid.
And a kind of process except oxidation on metal surface skin, comprising the following steps:
Original part to be derusted is put into 60 ~ 100s of immersion in mixed liquor 1, is taken out, is put into mixed liquor 2 and is dipped into metallic elements
The oxide skin on surface loosens, and takes out, and is put into mixed liquor 3 and is dipped to metal surface and gloss occur, takes out, be put into mixed liquor 4
40 ~ 120s is impregnated, is taken out, wipes metallic elements surface with the mixture of cleanser and starch.
The invention has the following advantages:
During process of the present invention except oxidation on metal surface skin, the first step is in dense liquor zinci chloridi
Highly acid effect under, by the oxidation and hydrochloric acid of nitric acid and the coordination of citric acid, make the oxygen that metal surface is firm
Change skin tentatively to loosen；Second step is by loosening oxidation on metal surface skin completely under the further acidification of hydrochloric acid and sulfuric acid；
Third step makes oxide skin thoroughly fall off from metal surface by the neutralization of acid with base of nitric acid, hydrochloric acid, concentrated phosphoric acid and oxide skin；The
Four steps pass through the strong coordination of disodium EDTA, and the remaining oxide in metal surface is made to form soluble cooperation
Object becomes metal surface completely to be completely removed, and tentatively has metallic luster；5th step, with starch and cleanser
Mixture wipes metal surface, the metallic luster for making metal surface occur being extremely brilliant.The metallic elements table handled by the present invention
Face is as bright as a sixpence, has extraordinary metallic luster.
