Description

technical field

[0001] The invention relates to the technical field of aluminum product processing, in particular to an aluminum alloy oxidation liquid recovery and cooling equipment crystallization removal system and process. Background technique

[0002] The aluminum alloy anodizing line slot layout in the prior art is as attached figure 1 shown. In the 10# tank anodic oxidation solution, the aluminum alloy with conductive surface is placed on the anode. Under the action of an external electric field, the process of forming an oxide film on the surface is called anodic oxidation, and the film produced is an anodic oxidation film or an electrochemical conversion film. The electrochemical oxide film is different from the natural oxide film. The oxide film has a stacked cell structure, each cell is a hexagonal cylinder, and its top is an arc-shaped and hexagonal star-shaped pore truncated surface. The oxide film has a two-layer structure, and the layer close to the base met...
