Problems solved by technology

Among these methods, mechanical polishing has a high cost in terms of high-temperature pickling and mechanical polishing equipment, auxiliary materials, and power consumption; although electrochemical polishing has a better polishing effect, the cost is relatively high, and it is easily limited by the distribution of power lines. Affect the color; chemical polishing is a kind of chemical corrosion under special conditions. It selectively dissolves the stainless steel surface by controlling the surface, so that the microscopic protruding parts of the stainless steel surface are preferentially dissolved compared with the concave parts, so as to achieve a smooth and bright surface.

Abstract

The invention provides polishing solution for front and rear covers of an electric motor. The polishing solution is prepared from the following raw materials: phosphoric acid, graphitic acid, heptadecafluorooctanesulfonic acid, linseed oil, sodium fluoborate, ammonium bicarbonate, disodium phosphate dodecahydrate, 4,4-diaminodiphenyl sulfide, polyethylene glycol stearate, trimethyl borate, derusting assistant, an additive and deionized water. The polishing solution provided by the invention is used for polishing the front and rear covers of the electric motor and is excellent in polishing performance; surfaces of the polished front and rear covers of the electric motor are silvery white and light; the added derusting assistant can effectively remove rust on the surfaces; the added additive has better dirt-removing power.

Description

technical field [0001] The invention relates to a polishing liquid for the front and rear covers of a motor. Background technique [0002] At present, the methods of polishing stainless steel in the metal processing industry mainly include mechanical polishing, chemical polishing and electrochemical polishing. [0003] Learn to polish etc. Among these methods, mechanical polishing has a high cost in terms of high-temperature pickling and mechanical polishing equipment, auxiliary materials, and power consumption; although electrochemical polishing has a better polishing effect, the cost is relatively high, and it is easily limited by the distribution of power lines. Affect the color; chemical polishing is a kind of chemical corrosion under special conditions. It selectively dissolves the stainless steel surface by controlling the surface, so that the microscopic protruding parts of the stainless steel surface are preferentially dissolved compared with the concave parts, so a...
