Electrophoretic coating represents a pinnacle of coating technology, where your objects are immersed in water-soluble paint, serving as the anode (anodic electrophoresis). A corresponding cathode is placed, and by passing direct current between these poles, the paint is uniformly applied to the object through both physical and chemical effects of the electrical current.
The comprehensive process flow for achieving exceptional electrophoretic coating on 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 integral processes occurring simultaneously.
1. Electrophoresis: In the presence of a DC electric field, positively and negatively charged colloidal particles migrate towards the opposite charged pole, a phenomenon also known as swimming.
2. Electrolysis: Oxidation and reduction reactions transpire at the electrodes, resulting in the formation of distinct oxidation and reduction phenomena on each electrode.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles move towards the anode on the template surface, releasing electrons, leading to an insoluble state deposition and forming a paint film.
4. Electroosmosis: Under the influence of the electric field, the solid phase remains stationary while the liquid phase moves, causing the water in the paint film to be discharged gradually, forming a dense paint film with high resistance and minimal water content.
For instance, in iron red epoxy electrophoresis paint: The system comprises modified epoxy resin, butanol, ethanol amine, talc, and iron red substances. Mixed with distilled water and subjected to a DC electric field, the paint separates into positively charged cations and negatively charged anions, undergoing a series of intricate physical, chemical, colloid, and electrochemical transformations.
The electrophoretic coating's swift application speed enables mechanized, automatic, and continuous operations, significantly reducing labor intensity. This method delivers a uniform and robust paint film, ensuring excellent coverage even on complex parts like welded seams, where conventional methods fall short.
Boasting a remarkable paint utilization rate of 90%-95%, electrophoretic paint uses water as a solvent, offering non-combustibility, non-toxicity, and ease of operation.
Once dried, the electrophoretic paint film exhibits superior adhesion and outperforms ordinary paints and conventional methods in rust resistance, corrosion resistance, and weather durability.
