⑴ Aluminum equipment for electrophoresis tank. Aluminum profile electrophoresis tanks are often designed as rectangular slots, and the size of the base depends on the size of the installation and hanging. The tank body is 4-6mm, and the steel plate lining is made of polypropylene or epoxy fiberglass. An overflow tank needs to be installed.
⑵ Power supply. The DC requirement is adjustable from 0 to 250A, and the current size is calculated based on 50A/㎡, approximately 2000A/slot. The ripple factor of the power supply must be less than 6%, and the larger its value, the greater the probability of producing pores in the electrophoretic coating.
⑶ Electrode. In anodic electrophoresis, aluminum profiles are used as anodes, and stainless steel or aluminum plates are used as cathode plates. The cathode area is twice the total area of the workpiece. The diaphragm is made of polypropylene fiber cloth.
⑷ Heat exchange system. Can ensure stable temperature of the tank solution.
⑸ Pre configured slots and automatic addition system. The pre preparation tank can complete the preparation of electrophoresis tank solution to ensure the achievement of normal parameters; The automatic addition system can ensure the amount of electrophoretic paint consumed by each slot of aluminum profiles is replenished, ensuring that the solid content of the electrophoretic slot is within the process range to ensure uniform film thickness.
⑹Ion exchange processing (IR) system. When aluminum profiles undergo anodic electrophoresis, the pH value of the cathode will continuously increase. The use of an ion exchange resin system can remove impurities from the tank solution, while anions and cations stabilize the pH value of the tank solution. If a reverse osmosis device (RO) is added, a closed-loop system can be achieved.
