Abstract
The invention discloses a method for removing an oxide film from the surface of copper and belongs to the technical field of metal cleaning. The method for removing the oxide film from the surface of copper has the advantages that the oxide film removal effect is good and the production cost is low. The method sequentially comprises the following steps: (1) uniformly mixing 1 part (by weight) of oxide film removing agent and 3-10 parts (by weight) of water, so as to obtain a mixed solution for removing the oxide film from the surface of copper; (2) soaking copper needing oxide film removal in the mixed solution for removing the oxide film from the surface of copper, obtained in the step (1), for 20-50 seconds in a shaking manner; (3) taking out soaked copper, and cleanly washing with water.
Description
Technical field
The present invention relates to a kind of method of copper removal surface film oxide, specifically, relate to a kind of method of removing brass, red copper surface oxide film, belong to metal cleaning technical field.
Background technology
Oxide film is that iron and steel at high temperature oxygenizement occurs and the corrosion product that forms, is made up of iron protoxide, Z 250, ferric oxide.Be from inside to outside: iron protoxide, Z 250, ferric oxide.Wherein iron protoxide short texture, a little less than provide protection, and Z 250, ferric oxide compact structure have better protecting.
Be oxidized membranous crisply, there is no extensibility, under mechanical effect and under hot-work effect, be easy to produce be full of cracks and depart from.Ferric oxide and iron protoxide generate ironic hydroxide under water effect, oxide film is expanded and chap, and even come off.
On original oxide film, always exist the crackle that deeply reaches matrix, when ionogen is poured into after crackle, iron and oxide film form galvanic cell.Oxide film is negative electrode, and iron is as anode and accelerated corrosion, and therefore the area of oxide film is larger, and the corrosion speed of steel substrate is faster, corrodes more serious.Therefore, before plating, the oxide film of metallic surface to be removed.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of removal oxide film effective, the method for the low copper removal surface film oxide of production cost.
For this reason, technical scheme provided by the invention is such: the method for this copper removal surface film oxide, comprises the steps: successively
1) 1 weight part deoxidation film and 3-10 weight parts water are mixed, obtain the mixed solution of copper removal surface film oxide;
2) the copper shake that needs oxide film dissolving is immersed in to step 1) 20-50 second in the mixed solution of described copper removal surface film oxide;
3) copper after soaking is taken out to washing totally;
Wherein: every liter of deoxidation film contains following component: hydrochloric acid 200-500g, oxalic acid 30-50g, fatty alcohol-polyoxyethylene ether 5-10g, alkylphenol polyoxyethylene 1-2g, thiocarbamide 2-5g, disodium ethylene diamine tetraacetate 5-10g, urotropine 5-10g, cresol sulfonic acid 60-100g, gelatin 5-10g, β mono-naphthols 2-5g, surplus is water.
Further, the method for above-mentioned copper removal surface film oxide, every liter of deoxidation film contains following component: hydrochloric acid 300-400g, oxalic acid 35-45g, fatty alcohol-polyoxyethylene ether 6-9g, alkylphenol polyoxyethylene 1.5g, thiocarbamide 3-4g, disodium ethylene diamine tetraacetate 6-9g, urotropine 6-9g, cresol sulfonic acid 70-90g, gelatin 6-9g, β mono-naphthols 3-4g, surplus is water.
Compared with prior art, technical scheme tool provided by the invention has the following advantages:
Technical scheme provided by the invention can be removed the oxide film on copper surface fast, simple to operate, removes oxide film effective, and production cost is low, and the finished product rate of gained is high.
