Electrophoretic coating is an advanced coating technology where the painted object is submerged in water-soluble paint serving as the anode (anodic electrophoresis). A corresponding cathode is positioned, and a direct current is passed between these poles, facilitating a uniform paint coat via the physical and chemical effects of the current.
The comprehensive process flow of electrophoretic coating on general metal surfaces is as follows: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Cleaning on the tank → Ultra-filtration → Drying → Off-line.
Electrophoretic coating typically encompasses four simultaneous processes.
1. Electrophoresis: Under the influence of a DC electric field, positively and negatively charged colloidal particles migrate towards the negative and positive directions respectively, a phenomenon also known as swimming.
2. Electrolysis: Redox reactions occur on the electrodes, resulting in the formation of oxidation and reduction phenomena on the respective electrodes.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles move towards the anode, release electrons near the template surface, and deposit in an insoluble state, creating a precipitated paint film.
4. Electroosmosis: In an electric field, the solid phase remains stationary while the liquid phase moves. Electroosmosis ensures that water in the paint film is gradually expelled, culminating in a dense paint film with minimal water content and high resistance, impeding even current flow.
5. Iron Red Epoxy Electrophoresis Paint Example: This system employs modified epoxy resin, butanol, ethanolamine, talc, and iron red substances. Mixed with distilled water, the paint undergoes separation into positively charged cations and negatively charged anions under a DC electric field, followed by intricate physical, colloidal, and electrochemical changes.
The electrophoretic coating process offers a rapid construction speed, enabling mechanized and automated continuous operation. This reduces labor intensity while ensuring a uniform paint film with strong adhesion. Even complex parts, such as the welded seams of fascia plates, receive a smooth and even coat, unattainable by conventional methods.
Electrophoretic paint boasts an impressive utilization rate of 90%-95%. Using water as the solvent, it presents non-combustible, non-toxic properties and is easy to handle.
The dried electrophoretic paint film demonstrates superb adhesion, with enhanced rust resistance, corrosion resistance, and weather resistance compared to ordinary paints and traditional application methods.
