Abstract
The invention discloses a reagent for removing oxide scale on the surface of copper and a preparation method thereof, and aims to provide a reagent which is high in stability and convenient to use and can be used for removing oxide scale on the surface of copper. The reagent is characterized by comprising the following components in each liter: 50-150g of ammonium persulfate, 50-150g of sulfuric acid, 50-80g of oxalic acid, 12-16g of fatty alcohol-polyoxyethylene ether, 3-5g of alkylphenol polyoxyethylene, 2-4g of thiourea, 5-8g of ethylene diamine tetraacetic acid, 5-8g of urotropine and the balance of water. The method for preparing the reagent for removing oxide scale on the surface of copper comprises the following steps: (1) weighing each component; and (2) putting the components weighed in the step (1) in a flask, adding water until the volume is 1L, and stirring for 3-9 minutes at normal temperature to obtain the reagent for removing oxide scale on the surface of copper. The reagent and the preparation method belong to the technical field of metal cleaning.
Description
Technical field
The present invention relates to a kind of reagent of copper removal surface scale, specifically, relate to a kind of reagent of removing brass, red copper surface oxide skin, belong to metal cleaning technical field.
Background technology
Oxide skin 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.
Oxidation cortex is crisp, there is no extensibility, under mechanical effect and under hot-work effect, is easy to generation and chaps and depart from.Ferric oxide and iron protoxide generate ironic hydroxide under water effect, oxide skin is expanded and chap, and even come off.
In original oxide skin, always exist the crackle that deeply reaches matrix, when ionogen is poured into after crackle, iron and oxide skin form galvanic cell.Oxide skin is negative electrode, and iron is as anode and accelerated corrosion, and therefore the area of oxide skin is larger, and the corrosion speed of steel substrate is faster, corrodes more serious.Therefore, before plating, want metallic surface protective membrane is removed.
