Abstract
The invention relates to a stainless steel chemical polishing liquid, which is a liquid prepared by mixing the following components: 5% of polyethylene glycol, 3% of concentrated sulfuric acid, 10% of sodium phosphate, 3% of potassium carbonate, 5% of ammonium chloride, 5% of sulfamic acid, 3% of glycerol, 10% of citric acid, 1% of sodium benzenesulfonate, 2% of ethylene glycol monomethyl ether, 1% of sodium dodecyl benzene sulfonate, 2% of EDTA, 1% of copper sulfate, and water. According the present invention, the stainless steel chemical polishing solution can clean and brighten the stainless steel surface, and has significant effect.
Description
Technical field
The present invention relates to Treatment of Metal Surface, and in particular to a kind of stainless steel chemical polishing solution, the polishing fluid is used to that the selective dissolution effect in the uneven region of sample surfaces to be eliminated polishing scratch, corrodes leveling.
Background technology
Stainless steel hardness is relatively low, belongs to the metal of more difficult polishing, and conventional method is not often satisfied the requirements with the mode of electrobrightening, but scene with mechanical polishing, and mechanical polishing and electrobrightening mode cannot be used.
A kind of stainless steel chemical polishing solution, rate of charge is respectively polyethylene glycol：5%th, the concentrated sulfuric acid：3%th, sodium phosphate：10%th, potassium carbonate：3%th, ammonium chloride：5%th, sulfamic acid：5%th, glycerine：3%th, citric acid：10%th, benzene sulfonic acid sodium salt：1%th, EGME：2%th, neopelex：1%、EDTA：2%th, copper sulphate：1%th, water：49%, such optimum choice makes the stainless steel polishing time most short, and effect is good.Stainless steel surfaces can be made more to clean and light, be easy to the stainless later stage to be surface-treated.
The content of the invention
It is an object of the invention to provide a kind of with the chemical polishing solution for improving stainless steel surfaces clean-up performance, being easy to the later stage to be surface-treated.
The present invention realizes in the following way purpose：Sulfuric acid and sulfamic acid are acid with strong oxidizing property, and passivation and dissolution are acted primarily as to stainless steel, can dissolve the oxide scale layer of stainless steel surfaces.
The metal ion that complexing agent can be generated with reaction forms complex ion, improves stainless steel surfaces quality, while can also improve the stability of pickle.
Fog inhibitor neopelex can form one layer of bubble film on polishing fluid surface, prevent the diffusion of volatility acid mist.
Described polyethylene glycol is thickener.
Described sodium phosphate, potassium carbonate, benzene sulfonic acid sodium salt are builder.
Described glycerine can prevent acid mist.
Described EGME is bleeding agent.
Described neopelex is solubilizer.
Described EDTA is complexing agent.
Specific embodiment
With reference to embodiments the present invention will be further described.

50g polyethylene glycol, the 30g concentrated sulfuric acids, 100g sodium phosphates, 30g potassium carbonate, 50g ammonium chlorides, 50g sulfamic acids, 30g glycerine, 100g citric acids, 10g benzene sulfonic acid sodium salts, 20g EGMEs, 10g neopelexes, 20g EDTA, 10g copper sulphate and 490ml water are pre-mixed.After being well mixed, that is, required stainless steel chemistry degreaser is obtained, its density is about 1.1g/cm3。
Obtained stainless steel chemical polishing solution is tested, can be seen by different test specimens, stainless steel surfaces after treatment are more cleaned and light.But because by being influenced each other except other factors, therefore the cleaning effect of test specimen is also different in polishing process, should be according to field condition flexible Application, appropriateness grasps various conditions, could obtain ideal cleaning effect.
It should be noted that, above example is only to illustrate technical scheme and unrestricted, although being described in detail to the present invention with reference to above-described embodiment, still technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention, all should cover in the middle of scope of the presently claimed invention.
