Electrophoretic coating represents a cutting-edge technology where the object to be painted is immersed in a water-soluble paint. As the anode in anodic electrophoresis, a corresponding cathode is set up, and a direct current passed between these poles ensures the paint is uniformly coated on the object through the power of physical and chemical reactions.
The process flow for electrophoretic coating on standard metal surfaces includes a meticulous sequence: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Tank cleaning → Ultra-filtration → Drying → Off-line.
Electrophoretic coating involves four simultaneous and intricate processes that ensure superior coating results.
1. Electrophoresis: Under a DC electric field, positively and negatively charged colloidal particles move towards their respective opposite poles, a phenomenon also known as swimming.
2. Electrolysis: Redox reactions occur on the electrodes, resulting in oxidation and reduction phenomena.
3. Electrodeposition: During electrophoresis, charged colloidal particles migrate to the anode surface, release electrons, and deposit in an insoluble state, forming a robust paint film.
4. Electroosmosis: Here, while the solid phase remains static, the liquid phase moves under an electric field. This process expels water from the paint film, eventually forming a dense, high-resistance paint film that even current struggles to pass through.
5. For instance, iron red epoxy electrophoresis paint comprises modified epoxy resin, butanol, ethanol amine, talc, and iron red. This mix, diluted with distilled water, undergoes complex physical, chemical, colloidal, and electrochemical transformations under a DC electric field.
Electrophoretic coating boasts a rapid construction speed, enabling mechanized and automated continuous operations. It reduces labor intensity, ensures uniform paint film, and delivers strong adhesion. Even challenging areas, like welding seams, achieve an even and smooth finish not possible with conventional methods.
With a remarkable paint utilization rate of 90%-95%, electrophoretic paint employs water as a solvent, offering benefits like non-combustibility, non-toxicity, and ease of use.
Post-electrophoresis, the dried paint film exhibits exceptional adhesion, surpassing ordinary paints and general methods in rust resistance, corrosion resistance, and weather resistance.
