Abstract
The invention discloses a stainless steel chemical polishing liquid which comprises the following components by weight: 30-50ml/L of nitric acid, 120-140ml/L of phosphoric acid, 100-120ml/L of hydrochloric acid, 1-4g/L of urea, 1-3g of corrosion inhibitor, 20-50g/L of brightener and 0.5-2g/L of surfactant. The stainless steel chemical polishing liquid has the advantages that a stainless steel workpiece treated by the stainless steel chemical polishing liquid is bright in mirror surface and has no dust; when work is carried out, volatilization amount of irritant acidic gas is little, and work environment is improved; and simultaneously, the polishing speed is stable.
Description
Technical field
The invention belongs to metal surface treatment technology, relate in particular to stainless steel chemical polishing.
Background technology
Stainless steel is because good machinery and chemical property is widely used in fields such as making medicine equipment, kitchen utensils, instrument, chemical industry equipment.Stainless steel is placed under air or sour environment for a long time, and the meeting oxidation by air forms the oxidation cortex of grey black, affects its appearance and corrosion resistance nature.Therefore usually need with carrying out chemical rightenning, during at present common chemical brightening solution polishing large, the bad control of polishing time of sour gas volatilization easily cause polishing excessively or polishing not.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides a kind of stainless steel chemical polishing solution, stainless steel is polished not can dust, outer optical surface light; Thereby and the less return visit that reduces sour gas of volatile acid content in the solution, improved Working environment; In addition, by the content of control inhibiter, stablize polishing velocity.
Technical scheme: for solving the problems of the technologies described above, the present invention by the following technical solutions: a kind of stainless steel chemical polishing solution comprises the component of following content:
Nitric acid 30～50ml/L;
Phosphatase 11 20～140ml/L;
Hydrochloric acid 100～120ml/L;
Urea 1～4g/L;
Inhibiter 1～3g/L;
Brightening agent 20～50g/L
Tensio-active agent 0.5～2g/L.
As preferably, described inhibiter is one or more the mixture in hexamethylenetetramine, poly aspartic acid, benzotriazole, sulfurio benzo thiazole, the cetylamine.
As preferably, described brightening agent comprises ether of cellulose or gelatin.
As preferably, described brightening agent also comprises aromatic amine.
As preferably, described aromatic amine is one or more the mixture in anisidine, mamino-trifluoromethyl benzene, the methylphenylamine.
As preferably, described tensio-active agent is polysorbas20, polysorbate60, sapn.
Beneficial effect: compared with prior art, the present invention has the following advantages: stainless steel work-piece becomes the minute surface light, without dust after polishing fluid polished finish of the present invention; And the volatilization of pungency sour gas is little during work, and Working environment improves; Has simultaneously stable polishing velocity.
