Abstract

The invention discloses a power supplying electrolyte for an organic acidification of an aluminum foil. The power supplying electrolyte for the organic acidification of the aluminum foil is composed of a power agent, an additive, and water, wherein the power agent is phosphoric acid, and the concentration is 20-60g/L; the additive is R'-H2PO4 or R'-HPO4, and the concentration is 0.1-1.0 g/L; and the R' is an active metal ion. According to the power supplying electrolyte for the organic acidification of the aluminum foil, a new power agent phosphoric acid is introduced into a feed tank to replace the original power agent ammonium adipate or ammonium dihydrogen citrate to enhance conductivity; the problem of curling and wrinkling of the aluminum foil which occurs during the organic acidification process for producing an electrode foil with high specific volume is completely solved without increasing the unit consumption of the electricity; the product qualification rate is improved by 30%; the stability of production operation is improved; the electrolyte cost is reduced by about 15%; and the invention is suitable for mass production of the electrode foil industry.

Description

technical field [0001] The invention specifically relates to an electrolytic solution for feeding power through organic acidification of aluminum foil. Background technique [0002] At present, the electrode foil formation method for aluminum electrolytic capacitors is to boil the electrolytically corroded aluminum foil at high temperature, and apply a voltage in a solution containing boric acid, organic acid or salt to form an anodic oxide film on the surface of the aluminum foil. In order to improve production efficiency, various manufacturers adopt four-level or even five-level treatment for chemical formation. When the power supply is pressurized, the first and second stages are generally powered by solid conductive rollers. Aluminum powder or various impurities in the air will accumulate on the surface of the conductive rollers, resulting in ignition, and the third, fourth and fifth stages are powered by liquid conduction. In the process of liquid conduction power supp...
