Electrophoretic coating is an advanced technology where the painted object is submerged in water-soluble paint, acting as the anode in anodic electrophoresis. Meanwhile, a cathode is positioned correspondingly, and direct current flows between these poles. This current induces physical and chemical effects, ensuring the paint is uniformly coated on the object, delivering a seamless finish.
The meticulous process flow of electrophoretic coating on general metal surfaces includes: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Cleaning in the tank → Ultra-filtration → Drying → Off-line.
Electrophoretic coating encompasses four simultaneous processes, each contributing uniquely to the exceptional finish.
1. Electrophoresis: Under a DC electric field, charged colloidal particles move towards opposite charges-this movement, also known as swimming, ensures comprehensive coverage.
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena that are integral to the coating process.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles move towards the anode on the template surface, releasing electrons and creating an insoluble, deposited paint film. This stage forms the foundational paint layer.
4. Electroosmosis: An electric field causes the liquid phase to move while the solid phase remains stationary. This process gradually expels water from the paint film, culminating in a dense, high-resistance paint film with minimal water content.
5. Taking iron red epoxy electrophoresis paint as an example: The system comprises modified epoxy resin, butanol, ethanolamine, talc, and iron red substances. When mixed with distilled water and subjected to a DC electric field, it separates into positively charged cations and negatively charged anions, undergoing a series of complex physical, chemical, and electrochemical changes.
Electrophoretic coating's construction speed is remarkable, facilitating mechanized and automatic continuous operation. This reduces labor intensity and ensures uniform paint films with strong adhesion. Even the hardest-to-coat areas, like fascia plate welding seams, achieve an even and smooth finish.
Remarkably efficient, the utilization rate of electrophoretic paint is between 90%-95%. Using water as a solvent, it boasts non-combustibility, non-toxicity, and straightforward operation, making it highly advantageous.
Post-drying, the paint film produced by electrophoresis exhibits superior adhesion. Its rust resistance, corrosion resistance, and weather resistance are significantly enhanced compared to ordinary paints and general construction methods.
