Description

Electrophoresis process

The general process flow of anodic electrophoresis is: workpiece pre-treatment (oil removal → hot water washing → rust removal → cold water washing → phosphating-hot water washing → passivation) → anode electrophoresis → workpiece post-treatment (clean water washing → drying)

1. Remove oil. The solution is generally a hot alkaline chemical degreasing solution with a temperature of 60°C (steam heating) and a time of about 20 minutes.

2. Wash in hot water. Temperature 60℃ (steam heating), time 2min.

3. Rust removal. Use H2SO4 or HCI, such as hydrochloric acid rust removal solution, HCI total acidity ≥ 43 points; free acidity > 41 points; add 1.5% cleaning agent; wash at room temperature for 10 to 20 minutes.

4. Wash in cold water. Wash in cold running water for 1 minute.

5. Phosphating. Use medium temperature phosphating (phosphating for 10 minutes at 60°C), and the phosphating solution can be commercially available finished products.

The above process can also be replaced by sandblasting →> water washing

6. Passivation. Use the chemicals matching the phosphating solution (provided by the manufacturer that sells the phosphating solution) and leave it at room temperature for 1 to 2 minutes.

7. Anodic electrophoresis. Electrolyte composition: H08-1 black electrophoretic paint, solid content mass fraction 9%~12%, distilled water mass fraction 88%~91%. Voltage: (70+10)V; time: 2~2.5min; paint liquid temperature: 15~35℃; paint liquid PH value: 8~8.5. Note that the workpiece must be powered off when entering and exiting the slot. During the electrophoresis process, the current will gradually decrease as the paint film thickens.

8. Wash with clean water. Wash in cold running water.

9. Drying. Bake in the oven at (165+5)℃ for 40~60 minutes.

Electrophoresis characteristics

The characteristics of anodic electrophoresis are:
The raw materials are cheap (generally 50% cheaper than cathodic electrophoresis), the equipment is simpler, and the investment is less (generally 30% cheaper than cathodic electrophoresis); the technical requirements are lower; the corrosion resistance of the coating is worse than that of cathodic electrophoresis (about 10% of the life of cathodic electrophoresis) quarter)
Characteristics of cathodic electrophoresis:
Because the workpiece is a cathode, no anode dissolution occurs, and the surface of the workpiece and the phosphating film are not damaged, so the corrosion resistance is high; electrophoretic paint (generally nitrogen-containing resin) has a protective effect on the metal, and the paint used is of high quality and price.
