Embodiment Construction

[0023] Please refer to figure 1 As shown, it shows the process flow of the preferred embodiment of the present invention, which is an anodic dyeing process that can remove the color without damage, including hanging the workpiece, chemical polishing, primary washing, oxidation, dyeing, secondary washing, Colorimetry and thickness measurement, non-destructive fading, sealing, three washings, drying, packaging and other steps.

[0024] The specific process of each step is as follows:

[0025] S1, Hanging the workpiece: refers to placing the workpiece to be dyed in the jig, and hanging the jig on the hanging machine that can move back and forth. The workpiece placement adopts the automatic feeding mode, which reduces manual participation, saves labor costs, and improves efficiency. The hanging machine is controlled by PLC program, which makes the moving process of the workpiece fully automatic.

[0026] S2, chemical polishing: refers to the movement of the hanger to make the w...

Abstract

The invention discloses an anode dyeing process capable of fading colors without loss. The process includes the steps of workpiece hanging, polishing, first water washing, oxidation, dyeing, second water washing, hole sealing, third water washing, drying, packaging and the like. The hole sealing requires colorimetric operation and thickness-measuring, when the thickness and dyeing color of an anodized film layer are not in conformity with specifications, non-loss fading is required, since the anodized film layer of the process has an isolating function, even if a strong acid/base is encountered, an internal structure can be protected from damage in a short time, thereby providing a basis for the non-loss fading, in the dyeing and fading steps, a fading solution is prepared for a dyeing solution and only reacts chemically with dyes to achieve the fading effect, however, the process does not damage the anodized film layer and achieves the purpose of no loss, which is beneficial to the rapid rework of the workpiece, re-anodizing and dyeing, and the problem that traditional process defective products cannot be processed again is solved.

Description

technical field [0001] The invention relates to the technology in the field of surface treatment of metal products, in particular to an anodic dyeing process capable of color fading without damage. Background technique [0002] As a main surface treatment method for aluminum materials, anodizing not only enhances the protective performance of the substrate, but also the unique microporous structure of the oxide film can endow the substrate with excellent dyeing performance, thereby significantly improving the decorative properties of aluminum materials. In the process of anodizing, different electrolytes and electrolysis conditions have different coloring effects on the produced oxide film layer. It is necessary to strictly control the composition concentration of the electrolytic bath and additives and the corresponding voltage value to obtain a set thickness. film layer. Coloring is carried out after oxidation is completed. If the color is wrong before sealing after color...
