Abstract

The invention discloses an anodizing acid-leaching improved process. The anodizing acid-leaching improved process comprises the following steps: A, anode pretreatment; B, using a sulfuric acid solution in an anodizing tank, and finishing electrolysis to form a film at a temperature of 20 DEG C and at a voltage of 12-14 v; C, feeding the sulfuric acid solution into a first surface regulating tank to be cleaned, wherein the temperature of the surface regulating tank is below 20 DEG C through a thermolator, and neutralizing residual acidic liquor in gaps under match of ultrasonic waves generatedby an ultrasonic generator to finish cleaning; D, feeding the sulfuric acid solution into a second surface regulating tank to be cleaned, wherein the temperature of the surface regulating tank is below 20 DEG C through a thermolator and neutralizing residual acidic liquor in gaps for the second time under match of ultrasonic waves generated by an ultrasonic generator to finish second time cleaning; E, carrying out dyeing at a certain PH value; and F, carrying out drying in a drying box. The anodizing acid-leaching improved process disclosed by the invention is reasonable in setting, guaranteesthe cleaning effect and the cleaning efficiency and overcomes the technical defect that in the prior art, acid leaching cannot be avoided fully.

Description

technical field [0001] The invention belongs to the technical field of anodic oxidation treatment technology, and in particular relates to an anodic oxidation acid regurgitation process. Background technique [0002] At present, the NMT process is widely used, and the technology development is uneven. The aluminum-plastic combined products still account for a relatively large proportion of unfavorable products (5% to 80%). According to the existing solution mode, from nano-processing, plastic raw materials, injection molds, injection molding parameters, anode and other processes to collaborative solutions, it is easy to cause mutual buck-passing and delay the project progress. When there is a gap of 0.03mm to 0.05mm between the aluminum part and the plastic, there will be acid liquid hidden in the anodizing process, and the acid liquid cannot be washed out after ordinary surface adjustment. During the dyeing process, the acid liquid will precipitate and change the local PH ...
