Abstract

The invention relates to the technical field of metal surface treatment, particularly relates to an electrophoresis process, and more particularly relates to a color electrophoresis process used for metal surface treatment. The process comprises following steps: 1) hanging up; 2) washing with ultrasonic wave; 3) washing with water twice; 4) performing cathodic electrolysis; 5) washing with water twice; 6) activating; 7) washing with water twice; 8) passivating; 9) washing with water twice; 10) activating; 11) washing with water for three times; 12) washing with pure water for three times; 13) performing anode paint electrophoresis; 14) spraying; 15) washing with pure water for three times; 16) dehydrating; 17) blowing with air; 18) baking at a high temperature; 19) taking down; 20) examining; and 21) packaging. By adoption of the technical scheme, the process overcomes the problem that traditional electrophoresis processes cannot achieve color treatment on metal surfaces, a product of the process is bright in color, and a plating is high in durability.

Description

technical field [0001] The invention relates to the technical field of metal surface treatment, in particular to an electrophoresis process. Background technique [0002] The electrophoretic coating process is a coating method that uses an external electric field to make the particles such as pigments and resins suspended in the electrophoretic liquid directional migrate and deposit on the surface of the substrate of one of the electrodes. [0003] The traditional electrophoretic coating process only supports single-color coating. For applications that require multiple colors, it is obvious that the existing technology cannot meet the requirements. Contents of the invention [0004] The object of the present invention is to provide a color electrophoresis process for metal surface treatment to solve the above technical problems. [0005] The technical problem solved by the present invention can adopt following technical scheme to realize: [0006] The color electrophores...
