ã€China Aluminum Network】 (1) electrophoresis tank aluminum equipment. Aluminum electrophoresis tanks are designed as rectangular rectangular slots. The internal size of the base is determined by the size of the hanging hanger. The slot body is 4 to 6 mm. Polypropylene or epoxy glass fiber reinforced plastic is used for the steel plate lining. An overflow tank is required.
(2) Power supply. DC requirements 0 ~ 250A adjustable, the current size is calculated according to 50A/?, about 2000A/slot. The corrugation factor of the power supply must be less than 6%. The larger the value is, the greater the probability of electrophoretic coating producing voids.
(3) Electrodes. In the anode electrophoresis, the aluminum profile is used as the anode, and the cathode plate is made of stainless steel or aluminum plate. The area of ​​the cathode is 1 time of the total area of ​​the workpiece. Polypropylene fiber cloth is used for the panel diaphragm.
(4) Heat exchange system. It can ensure that the bath temperature is stable.
(5) Pre-aligned tanks and automatic addition system. The preparation tank can complete the preparation of the electrophoresis bath to ensure that the normal parameters are achieved; the system can be automatically added to ensure that the amount of electrophoretic paint consumed by each aluminum section is covered, and the electrophoresis tank solids are kept within the process range to ensure that the membrane Thick uniform.
(6) Ion exchange processing (IR) system. During the anode electrophoresis of aluminum profiles, the pH of the cathode will increase continuously. The ion exchange resin system can be used to remove the impurities in the bath. The cathode and cation can stabilize the pH of the bath. If the reverse osmosis device (RO) is added, the closed circuit can be realized. system.
