The electrodeposition coating is a coating method in which a substrate having electrical conductivity is immersed in a bath of electrodeposition coating material diluted with water and having a relatively low concentration as an anode (or cathode), a cathode (or anode) corresponding thereto is provided in the bath, and a direct current is applied between the two electrodes for a certain period of time to deposit a uniform, water-insoluble coating film on the substrate. The cathode electrophoresis is a commonly adopted coating process, is a main means for improving the service life (corrosion resistance) of a coated object, is widely applied to industries such as automobiles, household appliances, machinery, hardware and the like, and endows a machined part with good performances such as decoration, corrosion resistance, weather resistance and the like. In cathode electrophoresis, the electrophoretic paint used is cationic (positively charged) resin and pigment slurry, and the coated object is the cathode. The initial reaction at the cathode is the electrolysis of water to form hydrogen and hydroxide ions, which results in a highly alkaline interfacial layer on the cathode surface, causing positively charged particles to agglomerate at the cathode (workpiece), and cations (resin and pigment) to react with the hydroxide ions to produce film deposits. Organic acid radical ions are continuously gathered in the anode area, and if the acids are not removed in time, the pH value of the bath solution is reduced, the stability of process parameters is influenced, the throwing power is influenced, the re-dissolubility of a coating film is increased, and the consumption of the electrode with positive electricity is accelerated. The anode adopts an ion exchange membrane structure, so that organic acid generated in the electrophoresis process can be removed in time, the stable parameters of the electrophoresis tank liquid are ensured, and the service life of the electrode is prolonged.

At present, tubular anodes are generally adopted in the coating industry, and plate anodes are also partially adopted. Wherein tubular anode simple structure, the anode plate area is less relatively, to the same work piece of application, then needs more tubular anode, has increased installation work load, does not also do benefit to the management, tubular anode then the anode plate area is great relatively, but comparatively heavy, and space occupation is big.
