Single tin salt electrolytic coloring method for vertical hanging type electrolytic cell
ActiveCN111218704AExtend working hoursFacilitated DiffusionAnodisationAluminum IonElectrolytic agent
The invention discloses a single tin salt electrolytic coloring method for a vertical hanging type electrolytic cell. The method comprises the following process steps of step S1, surface purificationtreatment of an aluminum product; step S2, preparation of an oxidation film: placing the aluminum product subjected to surface purification treatment in an oxidation tank, wherein the concentration ofsulfuric acid in the oxidation tank is 170-180 g / L, the concentration of aluminum ions is 12-16 g / L, the oxidation temperature is 16-17 DEG C, the voltage is 12.0-18.0V, and anodic oxidation is carried out for 30-60min; step S3, electrolytic coloring: placing the oxidized aluminum product in the electrolytic cell, wherein the pH of a single tin salt electrolyte is 0.5-0.8, the electrolysis temperature is 18-20 DEG C, the voltage of an alternating current power supply is 16-18V, and electrolytic coloring of the aluminum product in the circulating single tin salt electrolyte is carried out for200-250S; and step S4, water washing post-treatment. According to the single tin salt electrolytic coloring method for the vertical hanging type electrolytic cell, the champagne-color aluminum productwith bright and uniform color and strong metal texture can be obtained, the emission of nickel-containing wastewater and waste residues is greatly reduced, and the pollution discharge cost of enterprises is reduced.
