METHOD FOR ELECTROCHEMICAL ETCHING OF ALUMINUM FOIL FOR OBTAINING HIGHLY DEVELOPED SURFACE IN MANUFACTURING OF ALUMINUM ELECTROLYTIC CAPACITORS

摘要

A method for electrochemical etching of aluminum foil for obtaining a highly developed foil surface in manufacturing aluminum electrolytic capacitors comprises etching thereof in chloride solutions. Barbotage of chloride solutions by an inert gas is performed that allows the solution to be mixed and oxygen to be removed.
