The invention relates to the technical field of chemical decaling, in particular to descaling solution applicable to a stainless steel metal welded joint and a preparation method thereof. The descaling treatment solution for the stainless steel welded joint is prepared by mixing the following raw materials in percentage by weight at normal temperature: 11 to 22 percent of fatty alcohol-polyoxyethylene ether, 0.5 to 1 percent of alkylphenol polyoxyethylene, 3 to 6 percent of citric acid, 4 to 8 percent of tartaric acid, 0.5 to 1 percent of anhydrous sodium carbonate, 1 to 2 percent of triethanolamine, 1 to 2 percent of hydrochloric acid, 0.5 to 1 percent of sodium molybdate and 57 to 78.5 percent of water. The descaling treatment solution for the stainless steel welded joint is easy in operation, has good descaling effect, does not corrode the surface of the stainless steel, maintains the glossiness of the stainless steel, can be reused, is harmless during skin contact, low-carbon and environment-friendly, and saves cost.
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 handle, though can play the effect of scale removal, strong acid has intensive corrodibility to stainless steel surface, makes the attenuation of stainless steel thickness.Because it is nitric acid or hydrofluoric acid are harmful, therefore necessary careful when scale removal in addition, there is unsafe hidden danger.Particularly have the tart flavour of harmful toxins in nitric acid or the 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 the prior art, provide a kind of commissure black sediment of can removing not corrode stainless steel again, stainless steel weld joint scale removal treatment solution 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 scale removal treatment solution is mixed and made into by following raw materials by weight percent:
Preferred stainless steel weld joint scale removal treatment solution is a stainless steel weld joint scale removal working fluid, and described stainless steel weld joint scale removal working fluid is mixed and made into by following raw materials by weight percent:
After stainless steel weld joint scale removal working fluid used for some time, descale effect was not obvious, needed this moment to add stainless steel weld joint scale removal annex solution, and described stainless steel weld joint scale removal annex solution is mixed and made into by following raw materials by weight percent:
A kind of preparation method of stainless steel weld joint scale removal treatment solution has following steps:
(1), under the normal temperature, adding weight percent in stirrer is the water of 57%-78.5%;
(2), throw in the fatty alcohol-polyoxyethylene ether that weight percent is 11%-22% while stirring;
(3), throw in the alkylphenol polyoxyethylene that weight percent is 0.5%-1% while stirring;
(4), throw in the citric acid that weight percent is 3%-6% while stirring;
(5), throw in the tartrate that weight percent is 4%-8% while stirring;
(6), throw in the anhydrous sodium carbonate that weight percent is 0.5%-1% while stirring;
(7), throw in the trolamine that weight percent is 1%-2% while stirring;
(8), throw in the hydrochloric acid that weight percent is 1%-2% while stirring;
(9), throw in the Sodium orthomolybdate that weight percent is 0.5%-1% while stirring;
(10), all reinforced back restir that finishes was finished product in 20-30 minute.
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 handled; 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 scale removal treatment solution can reuse, and skin contact is not had injury, and low-carbon environment-friendly is saved cost.
