| titleOfInvention | Manufacturing method of medium-high pressure corrosive foil for aluminum electrolytic capacitors |
| abstract | The present invention discloses a method for producing a medium-high pressure corrosive foil for an aluminum electrolytic capacitor, and the method includes the following steps. Pretreatment by immersion with sodium hydroxide solution using medium-high pressure electronic aluminum foil; pitting corrosion by applying electric current to hydrochloric acid and sulfuric acid solution; reamer corrosion using hydrochloric acid, sulfuric acid and phosphoric acid solution; nitric acid solution Immerse in; after cleaning with pure water, perform tanning treatment for primary nitrogen gas protection and secondary tanning treatment. The present invention performs a two-step annealing heat treatment including a temperature rise step, a primary constant temperature step, a linear temperature change step, and a secondary constant temperature step. The present invention utilizes the recovery and recrystallization process of aluminum metal by performing an annealing treatment for secondary nitrogen gas protection to improve the bending performance of the electrode foil, and the corrosive foil obtained by the present invention is subjected to a chemical conversion treatment. After that, the bending performance is improved by 20% or more, and it plays an important promoting action for miniaturization of aluminum electrolytic capacitors. |
