Abstract

The invention relates to the technical field of aluminum material oxidation, discloses an aluminum alloy anodic oxidation electrolyte and an anodic oxidation system process, and comprises the aluminum alloy anodic oxidation electrolyte and the aluminum alloy anodic oxidation system process. According to the method, the conduction condition of the contact positions of a conductive copper base, a conductive copper aluminum block, a hanging tool and a conductive beam must be checked before anodic oxidation, grinding is conducted frequently, cooling water of the conductive copper base must be opened before anodic oxidation, whether the conductive beam is bent or not must be checked, the bent conductive beam must be replaced, and after oxidation is finished, a crane hook can be hung on a conductive beam hook; in the neutralizing process, the profile needs to move up and down in a reverse inclined mode, residual alkali liquor in an inner hole of the profile is fully neutralized, dust on the surface of the profile is removed, the neutralized profile can enter an anodic oxidation tank after being subjected to secondary washing, inspection of the surface quality of the neutralized profile needs to be enhanced, and the sand surface condition of the surface of the profile is inspected; and whether surface defects such as dust hanging, burrs, piebald and welding lines exist or not is judged, so that timely treatment and reworking are facilitated.

Description

technical field [0001] The present application relates to the technical field of aluminum oxidation, in particular to an aluminum alloy anodizing electrolyte and an anodic oxidation system process. Background technique [0002] Using the sulfuric acid anodizing process to improve the protective performance and decorative properties of aluminum alloys is a long-standing process method; [0003] For example, the Chinese patent discloses: "An acidic solution for anodic oxidation of aluminum alloy and its preparation method", publication number: CN107937956A, which expands the process temperature range, and can still maintain a dense and complete oxide film at 40°C. The improved anodic oxidation treatment 30 to 40 minutes, can achieve the film thickness and corrosion resistance of the traditional treatment of 40 to 60 minutes, improve production efficiency, and at the same time ensure the quality of the film; [0004] In the process of anodizing aluminum alloy, color difference...
