Electrophoretic coating is a revolutionary technique where the target object, serving as the anode, is immersed in water-soluble paint. With a corresponding cathode in place, a direct current is applied, ensuring an even and uniform coat on the object through the synergistic physical and chemical effects of the current.
The meticulous process flow for electrophoretic coating on 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, resulting in an impeccable finish.
Electrophoretic coating seamlessly integrates four concurrent processes, delivering top-notch results.
1. Electrophoresis: Under the influence of a DC electric field, charged colloidal particles move towards oppositely charged electrodes, a dynamic process also known as swimming.
2. Electrolysis: This involves redox reactions at the electrodes, leading to oxidation and reduction phenomena, enhancing the coating's efficiency.
3. Electrodeposition: Colloidal particles near the anode release electrons, forming an insoluble paint film on the template surface through deposition and precipitation.
4. Electroosmosis: Here, the liquid phase moves while the solid phase stays put under the electric field's influence. This process gradually expels water from the paint film, resulting in a dense, high-resistance, low-moisture paint film.
5. For instance, iron red epoxy electrophoresis paint involves a system of modified epoxy resin, butanol, ethanol amine, talc, and iron red substances. Mixed with distilled water and subjected to a DC electric field, it undergoes complex physical, chemical, and electrochemical transformations.
Electrophoretic coating offers a high-speed construction process, enabling mechanized and automated continuous operations. This reduces labor intensity and ensures a uniform paint film with strong adhesion, even on hard-to-coat areas like fascia plate welding seams.
Remarkably, the paint utilization rate reaches 90%-95%. Using water as a solvent, electrophoretic paint boasts non-combustibility, non-toxicity, and ease of operation.
Post-electrophoresis, the dried paint film showcases outstanding adhesion, superior rust resistance, corrosion resistance, and weather resilience, far surpassing ordinary paints and conventional methods.
