| description | A medium-high voltage electronic aluminum foil corrosion pretreatment method comprises the following steps: placing an aluminum foil into pure water or aqueous solution containing ammonia water or amine at the temperature between 70 and 100 DEG C for treatment, performing proper heat treatment after treatment, and generating a hydrated oxidation film with uniformly distributed defects on the surface of the aluminum foil after treatment. During pitting corrosion, Cl is easily transmitted to the surface of the aluminum foil through water and defects in the hydrated oxidation film, so that the pitting uniformity of a high-voltage aluminum foil can be improved, the possibility of hole combination is reduced, and the specific capacitance of the aluminum foil is obviously improved on the premise of not reducing the mechanical strength and the bending performance of the aluminum foil. |
