Electrophoretic coating is an advanced technology where the substrate is immersed in a water-soluble paint solution as the anode (anodic electrophoresis), with a cathode placed opposite to it. When direct current is applied, the paint evenly coats the object through the combined physical and chemical effects of the current.
The detailed process flow for electrophoretic coating on standard metal surfaces includes: 1. Pre-cleaning → 2. On-line → 3. Oil removal → 4. Washing → 5. Rust removal → 6. Washing → 7. Neutralization → 8. Washing → 9. Phosphating → 10. Washing → 11. Passivation → 12. Electrophoretic coating → 13. Cleaning on the tank → 14. Ultra-filtration → 15. Drying → 16. Off-line.
Electrophoretic coating encompasses four intricate processes conducted simultaneously.
1. Electrophoresis: Colloidal particles, charged either positively or negatively, move towards their respective oppositely charged electrode under the influence of a direct current electric field, an action also known as 'swimming.'
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena.
3. Electrodeposition: Charged colloidal particles migrate towards the anode, release electrons upon reaching the template surface, and precipitate to form an insoluble paint film.
4. Electroosmosis: Under an electric field, the solid phase remains stationary while the liquid phase moves, expelling water from the paint film, resulting in a dense, high-resistance film that is nearly impermeable to current.
For example, iron red epoxy electrophoresis paint is composed of modified epoxy resin, butanol, ethanol amine, talc, and iron red substance. When mixed with distilled water and subjected to a DC electric field, it undergoes complex physical, chemical, colloid chemistry, and electrochemical changes.
Electrophoretic coating boasts rapid construction speeds and enables mechanized, automated, and continuous operation. This reduces labor intensity and produces a uniform, strongly adhering paint film. Even difficult-to-coat areas, such as fascia plate welds, achieve smooth, even coverage.
With a paint utilization rate of 90%-95%, electrophoretic paint stands out for its use of water as a solvent, providing benefits like non-combustibility, non-toxicity, and ease of operation.
The paint film created through electrophoresis exhibits excellent adhesion and superior rust, corrosion, and weather resistance compared to ordinary paints and conventional methods.
