永旺彩票The electrophoresis tank is for storing electrophoretic paint, and the objects to be coated are electrophoretic coated in it. It is divided into main tank and auxiliary tank, and the paint overflows from the outlet part to the auxiliary tank. The tank liquid circulation system is composed of a circulating pump, a filter, a pipeline in the tank, a nozzle, etc. The piping is set at the bottom of the tank, and the tank liquid circulation nozzle sprays the tank liquid to agitate the tank to keep the paint uniform in the tank and prevent the tank liquid from being damaged. Precipitate, remove the diffused electrolytic bubbles. The size of the tank can be designed according to the customer's workpiece size and output.

The electrophoresis line generally includes four simultaneous processes:

1. Electrophoresis: under the action of a direct current electric field, the positive and negatively charged colloidal particles move in the negative and positive direction, also known as swimming.

2. Electrolysis: oxidation-reduction reactions are carried out on the electrodes, but oxidation and reduction phenomena are formed on the electrodes.

3. Electrodeposition: Due to the effect of electrophoresis, the charged colloidal particles moved to the vicinity of the anode emit electrons on the surface of the template, and deposit in an insoluble state. At this time, the paint film is formed.

永旺彩票4. Electroosmosis: Under the action of an electric field, the solid phase does not move while the liquid phase moves. Electroosmosis causes the water content in the paint film to be gradually drained out of the paint film, and then forms a dense paint film with a low water content and a relatively high electrical resistance, which can hardly even pass through the current.

After the electrophoretic paint is mixed with distilled water, under the action of a DC electric field, Separate into positively charged cations and negatively charged anions, and carry out a series of complex physical, chemical, colloidal, and electrochemical processes.
