Description
Technical field
The present invention relates to the chemical cleaning technical field, especially a kind of cleaning mixture that is applicable to the stainless steel metal weld seam and preparation method thereof.
Background technology
According to the automobile industry in the whole nation, fuel tank, water tank that full-sized car, passenger vehicle, lorry, car etc. have all adopted the 316L stainless steel plate to make, vapor pipe, but stainless weld black sinter is difficult to remove.In order to remove these sinters, traditional method is to utilize nitric acid or hydrofluoric acid to process, although can play the effect of scale removal, strong acid has strong corrodibility to stainless steel surface, makes the attenuation of stainless steel thickness.In addition due to nitric acid or hydrofluoric acid harmful, therefore must be careful when scale removal, have unsafe hidden danger.Particularly have the tart flavour of harmful toxins in nitric acid or hydrofluoric acid, not only human body is had the strong impulse sense, and the acid mist severe contamination air that produces, the discharging of waste acid water is the severe contamination water resources also.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provide a kind of commissure black sediment of can removing not corrode again stainless steel, stainless steel weld joint dirty removing processing liquid harmless and free from environmental pollution and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: a kind of stainless steel weld joint dirty removing processing liquid is become by the mixed raw material of following weight percent:
The content of wherein said hydrochloric acid is 31%.
Preferred stainless steel weld joint dirty removing processing liquid is stainless steel weld joint scale removal working fluid, and described stainless steel weld joint scale removal working fluid is become by the mixed raw material of following weight percent:
The content of wherein said hydrochloric acid is 31%.
After stainless steel weld joint scale removal working fluid used for some time, descale effect was not obvious, needed to add stainless steel weld joint scale removal annex solution this moment, and described stainless steel weld joint scale removal annex solution is become by the mixed raw material of following weight percent:
The content of wherein said hydrochloric acid is 31%.
A kind of preparation method of stainless steel weld joint dirty removing processing liquid has following steps:
(1), under normal temperature, adding weight percent in stirrer is the water of 57%-78.5%;
(2), throw in while stirring the fatty alcohol-polyoxyethylene ether that weight percent is 11%-22%;
(3), throw in while stirring the alkylphenol polyoxyethylene that weight percent is 0.5%-1%;
(4), throw in while stirring the citric acid that weight percent is 3%-6%;
(5), throw in while stirring the tartrate that weight percent is 4%-8%;
(6), throw in while stirring the anhydrous sodium carbonate that weight percent is 0.5%-1%;
(7), throw in while stirring the trolamine that weight percent is 1%-2%;
(8), throw in while stirring the hydrochloric acid that weight percent is 1%-2%;
(9), throw in while stirring the Sodium orthomolybdate that weight percent is 0.5%-1%;
(10), all reinforced the stirring again after complete was finished product in 20-30 minute;
The content of wherein said hydrochloric acid is 31%.
Principle of work of the present invention is: alkylphenol polyoxyethylene and anhydrous sodium carbonate have played fat abstraction, remove the grease on stainless steel weld joint surface; Fatty alcohol-polyoxyethylene ether and Sodium orthomolybdate are strengthened harder dirt, oxide skin, hard oil and the sinter of bull pine weld face intensity; Citric acid, tartrate and the hydrochloric acid bad thing of bull pine are before promptly processed; Sodium orthomolybdate, trolamine and anhydrous sodium carbonate are in the stainless steel weld joint surface adsorption that cleans up and generate one deck passive film.
The invention has the beneficial effects as follows: the present invention is simple to operate, and features high scale-removing effect is not corroded stainless surface simultaneously, keeps stainless glossiness; And stainless steel weld joint dirty removing processing liquid can reuse, and without injury, low-carbon environment-friendly is saved cost to skin contact.
