Abstract

The invention relates to an aluminum foil formation technology, and discloses a two-level formation system for aluminum foil. The problems that an oxidation film is prone to being damaged in the aluminum foil producing process and the system cost is high according to a traditional aluminum foil formation process are solved. The two-level formation system for aluminum foil is composed of a foil placing system, a primary power supply system, a first-level electrolytic cell, a secondary power supply system, a second-level electrolytic cell, an intermediate treatment system, a thermal treatment system, a finish machining system, a drying system and a foil collecting system, wherein the foil placing system, the primary power supply system, the first-level electrolytic cell, the secondary power supply system, the second-level electrolytic cell, the intermediate treatment system, the thermal treatment system, the finish machining system, the drying system and the foil collecting system are sequentially connected. In addition, the invention discloses a corresponding two-level formation method. The two-level formation system and method are suitable for formation of aluminum foil.

Description

technical field [0001] The invention relates to an aluminum foil formation technology, in particular to a secondary formation system and method for an aluminum foil. Background technique [0002] Electrode aluminum foil is the key material for manufacturing aluminum electrolytic capacitors, and the quality of electrode aluminum foil directly determines the quality of aluminum electrolytic capacitors. This puts extremely high demands on the entire production process of high-pressure chemical synthesis to produce aluminum foil. After the surface of the aluminum foil is corroded and multi-stage chemically formed, an aluminum oxide film with a stable surface and good insulation performance is formed, and then it becomes a finished electrode aluminum foil. [0003] Traditional aluminum foil formation systems such as figure 1 As shown, it includes a sequentially connected foil release system, the first power supply system, the first-level electrolytic tank, the second-level elec...
