Embodiment Construction
[0010] The present invention will be further described below with specific examples.
[0011] The chemical formation method of the anode aluminum foil of the present invention sequentially includes pretreatment, multi-stage voltage empowerment to form an oxide film on the surface of the aluminum foil, and repeatedly destroying and repairing the oxide film. In order to add medium and high voltage aluminum foil from 170V to 200-1000V, generally 3-6 levels of voltage empowerment are required. Before and after the aluminum foil enters different weak acid baths, it needs to be washed with water to remove the acid residue on the surface of the aluminum foil. In addition, for repeated damage repairs, an oven is generally used to crack the oxide film on the surface of the aluminum foil, and then a constant voltage oxidation repair is performed in a boric acid solution. The aluminum foil is also washed with water before entering the oven. The washing method first uses pure water for pr...
