NdFeB magnetic materials are emerging in the material industry in recent years. In addition to the traditional electroplating treatment, electrophoretic coating also has a place, but compared with ordinary iron-based products, there are some differences in process processing.

Magnetic electrophoresis process:

Equipment configuration and precautions:

1. 1-2 sets of necessary ultrasonic equipment.

2. Electrophoresis tank, anode circulation system, ultrafiltration system, bag filter system (50 μ m-100 μ m), bath temperature monitor.

3. Pure water ensures a conductance of less than 5 μs.

4. The pure water in front of the electrophoresis tank should be tested daily. The conductance should not exceed 20 μs. The pure water in the pure water washing tank after electrophoresis should not exceed 50 μs per day.

5. Electrophoresis paint parameter control in electrophoresis tank

6. PH value > 6.0 is less than the upper limit, try to control, the upper limit of the normal value.

7. Guarantee 25% > solids > 20% is preferred.

8. Ensure that 22% > ash > 18% is better.

9. Electrophoresis bath control principle, high solids, high ash, the upper limit of PH is the principle.

10. Sintered magnet electrophoresis coating is easy, and the bonded magnet is easy to appear abnormal in production due to its low density. In addition to finding reasons in electrophoresis, it should be traced back to the bonding process, raw materials, especially density. Do not try to improve.
