Electrophoretic coating is a cutting-edge technology where the painted object, acting as the anode in an anodic electrophoresis setup, is immersed in a water-soluble paint. A cathode is placed accordingly, and direct current is passed between the two poles. This process ensures an even and flawless coat on the object due to the physical and chemical effects induced by the current.
The seamless process flow of electrophoretic coating for metal surfaces includes: 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 comprises four concurrent processes that work in harmony.
1. Electrophoresis: In a DC electric field, charged colloidal particles migrate towards their respective oppositely charged electrodes, a phenomenon also known as swimming.
2. Electrolysis: Distinct redox reactions occur at each electrode, leading to oxidation and reduction phenomena on the electrodes.
3. Electrodeposition: Charged colloidal particles are driven to the anode's vicinity, where they release electrons and deposit in an insoluble state, forming a paint film.
4. Electroosmosis: Under an electric field, the liquid phase moves while the solid phase remains stationary. This process effectively expels water from the paint film, resulting in a dense, high-resistance film with minimal water content.
For instance, iron red epoxy electrophoresis paint involves an epoxy resin system modified with butanol, ethanol amine, talc, and iron red pigment. When mixed with distilled water and subjected to a DC electric field, it dissociates into cations and anions, undergoing complex colloidal and electrochemical changes.
Electrophoretic coating boasts rapid construction speed, enabling mechanized and automated continuous operations. This reduces labor intensity and ensures a uniform, smooth, and strongly adhesive paint film, even on challenging areas such as welding seams.
The paint utilization rate is impressively high at 90%-95%. Using water as a solvent, electrophoretic paint is non-combustible, non-toxic, and user-friendly.
The dried paint film post-electrophoresis exhibits superior adhesion, and enhanced rust, corrosion, and weather resistance compared to conventional paints and application methods.
