Chromium-plated part cleaning solution and use method thereof

Abstract

The invention provides a chromium-plated part cleaning solution. The chromium-plated part cleaning solution is aqueous solution containing sulfuric acid, nitric acid and hydrofluoric acid, and the concentrations of sulfuric acid, nitric acid and hydrofluoric acid are 15-25 ml / L, 45-80 ml / L and 5-20 ml / L, respectively. In use, duster cloth is dipped in the chromium-plated part cleaning solution to wipe the surface of a chromium-plated part, or the chromium-plated part cleaning solution is smeared on the surface of the chromium-plated part and duster cloth wipes the surface of the chromium-plated part, and the chromium-plated part is flushed with clear water for at least twice; the cleaning of the chromium-plated part cleaning solution to the chromium-plated part is more complete, and the chromium corrosion is hardly caused; furthermore, the cleaning cost is low, the operation is simple, the time is saved, the reduction of the labor intensity and the improvement of the working efficiency are facilitated, the safety and the reliability are achieved, the quality of a cleaned work piece is ensured, and the subsequent production is facilitated.

Description

technical field [0001] The invention relates to a chemical cleaning solution, in particular to a cleaning solution for chrome-plated parts and its application method. Background technique [0002] After the electroplating is completed, the surface of the plated piece needs to be cleaned to achieve the purpose of cleaning the residual electroplating solution on the surface of the plated piece. The traditional cleaning method is a multi-channel cleaning method, that is, first use ultrasonic waves to remove the wax on the surface of the parts, and then use sulfuric acid with a concentration of 1-2ml / L for pickling after 2 times of water washing, and then 2 times of water washing after pickling. . Using this process to treat chrome-plated parts, the chromic anhydride remaining on the surface of chrome-plated parts cannot be cleaned, which affects the cleaning effect of the surface of chrome-plated parts.
