Description
Technical field
The present invention relates to a kind of normal tamperature environmental protection iron and steel anti-rusting liquid for removing oil, be mainly used in oil removing, rust cleaning in the metallic substance Coating Pretreatment processes such as iron and steel.The invention belongs to chemical method cleaning metal surface processing technology field.
Background technology
Ferrous materials spray, before the operation such as plating, its surface all must be processed, to remove the oxide skin that the surface produces in the course of processing.At present, various effective degreasing and rust removal technology are widely used industrial.
Chemical rust removing claims again acid pickling and rust removing, mainly is the solution oxide compound generation chemical reaction surperficial with it that utilizes the chemical substances such as acid, generates solvable or insoluble metal-salt, thereby reaches the purpose of rust cleaning.Although some present technology have overcome traditional degreasing and rust removal process portion shortcoming, cost is high mostly, energy consumption is high, and can't really effectively solve a large amount of waste gas, waste water and the waste residues of generation in acid cleaning process.
Summary of the invention
The present invention avoids the deficiencies in the prior art part, has proposed a kind of novel anti-rusting liquid for removing oil.This anti-rusting liquid for removing oil preparation is simple, can carry out under normal temperature condition; Degreasing and rust removal efficient is high, and corrosion inhibition is good, can establishment acid mist, belong to environmentfriendly products, product cost is low and can use continuously.
The present invention is that the technical scheme that its technical problem of solution adopts is: a kind of normal tamperature environmental protection iron and steel anti-rusting liquid for removing oil, its chief component (mass percent) is: mineral acid 82%-94.5%, hydrofluoric acid 4%-8%, oxalic acid 0.3%-3%, compound surfactant 0.2%-2%, sodium lauryl sulphate 0.5%-3%, compound corrosion inhibitor 0.5%-2%.
Compound method of the present invention is, with mineral acid as basic solution, the hydrofluoric acid and the oxalic acid that progressively add metering, after mixing, add urotropine, compound surfactant and compound highly effective inhibiter, stir, namely be mixed with normal tamperature environmental protection stainless steel of the present invention oil removing except acid solution.Each components description is as follows:
1. above-mentioned mineral acid is the mixing solutions of hydrochloric acid and dilute sulphuric acid, and Main Function is the oxide compound of removing steel surface, the oxide compound of quick dissolved iron, and effect is high, and pickling rear surface state is good.
2. hydrofluoric acid has stronger dissolving power to the oxide compound of indissoluble, and fluorion is a kind of good complexing agent, can form complexing ion with the metal ion that reaction generates, and improves the stainless steel surface quality, also can improve the stability of pickle solution simultaneously.
3. oxalic acid plays derusting action.
4. above-mentioned compound surfactant is nonionic surface active agent OP-10 and anion surfactant polyoxyethylenated alcohol sodium sulfate, with the more efficient low-foaming surfactant of both composite formation, have the effects such as moistening, emulsification, infiltration, decontamination, reduce the interfacial tension of stainless steel surface and solution, improve the etch ability of pickle solution, process the clean light in rear surface, not yellowing.Simultaneously, form fine and close molecule tunic on the acid solution surface, have the effect that suppresses acid mist.
5. sodium lauryl sulphate is used for suppressing acid mist, helps simultaneously to remove greasy dirt.
6. above-mentioned composite sustained release dosage is urotropine and polyethenoxy sorbitan oleic acid ester (tween-80), with both composite formation high-efficient corrosion inhibitors, can control speed of response, prevents excessive erosion, avoids the metal hydrogen embrittlement, reduces simultaneously stainless corrosion loss.
The concentration of hydrochloric acid is 15% in the component, and dilute sulphuric acid concentration is 20%, and other reagent are chemical pure.The present invention has following beneficial effect:
1. degreasing and rust removal liquid making method of the present invention is simple, and cost of material is cheap;
2. anti-rusting liquid for removing oil rust cleaning speed of the present invention is fast, at normal temperatures, can finish degreasing and rust removal by an operation, and the surface treatment time is 5-15 minute, has reduced labour intensity, has improved working efficiency;
3. anti-rusting liquid for removing oil of the present invention can use continuously, need not waste discharge.After pickling for some time, anti-rusting liquid for removing oil has certain consumption, at this moment, the oxide skin at the bottom of the pickling tub is cleared out, and adds the pickle solution of 10%-30% (mass percent), can continue to use, and not affect rust cleaning speed;
4. the compound corrosion inhibitor and the compound surfactant that add of anti-rusting liquid for removing oil of the present invention, when reducing cost, can the establishment acid mist, improve the surface treatment quality, the steel surface that cleans out presents bright silvery white metalluster;
5. the ferrous materials after anti-rusting liquid for removing oil of the present invention is processed can be at indoor reservation non-corrosive more than three months.
