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 technology
Metal through various working processes or for a long time storage, use during, surface will appear one layer of oxide skin or
Evidence of oxide makes its corrosion resistance substantially reduce, and not only influences beautiful and the later stage 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 path, of high cost, energy consumptions
Greatly, the shortcomings of pollution is heavy, work situation is poor.The present invention successfully invented it is a kind of it is of low cost, pollution is small, derusting is clean, technique
A kind of process except oxidation on metal surface skin being simple and convenient to operate.
Invention content
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.The derusting process of the present invention, with of low cost, pollution is small, derusting is clean, technique
The advantages that being simple and convenient to operate.
In order to achieve the above objectives, the technical solution used in the present invention is：A kind of technique side except oxidation on metal surface skin
Method, including：
Mixed liquor 1：Water, concentrated nitric acid, concentrated hydrochloric acid, zinc chloride, citric acid ratio be 80 ~ 100ml：10~20ml：15~35ml：10
