Electrophoretic coating is a revolutionary technology where the object to be painted is immersed in water-soluble paint, acting as the anode (anodic electrophoresis), with a corresponding cathode set up. A direct current is passed between these poles, enabling the paint to evenly coat the object through the physical and chemical effects of the current. This method ensures a smooth, consistent finish and enhances the durability of the coating.
The detailed process flow of electrophoretic coating for 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. Each step is meticulously designed to ensure the highest quality finish.
Electrophoretic coating encompasses four intricate processes working in tandem.
1. Electrophoresis: Under a DC electric field, positively and negatively charged colloidal particles swim towards their respective electrodes, ensuring an even distribution of the paint.
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena, which further stabilize the coating process.
3. Electrodeposition: Due to electrophoresis, colloidal particles release electrons near the anode, leading to their deposition in an insoluble state. This creates a durable paint film on the surface.
4. Electroosmosis: The electric field causes the liquid phase in the paint film to move out while the solid phase remains stationary. This results in a dense, low-water-content paint film with high resistance, ensuring a lasting finish.
5. Iron Red Epoxy Electrophoresis Paint: Utilizing a modified epoxy resin, butanol, ethanol amine, talc, and iron red substances, this paint system undergoes a series of complex physical, chemical, and electrochemical changes under a DC electric field, separating into positively charged cations and negatively charged anions for a robust coating.
The electrophoretic coating process is renowned for its fast construction speed, enabling mechanized and automated continuous operations. This significantly reduces labor intensity, ensures uniform paint films, and offers strong adhesion. Even hard-to-coat areas, like welding seams, receive an even and smooth finish, surpassing traditional coating methods.
With a paint utilization rate of 90%-95%, electrophoretic paint is not only efficient but also environmentally friendly. Using water as a solvent, it offers non-combustibility, non-toxicity, and ease of operation, making it a superior choice for modern coating needs.
Post-electrophoresis, the dried paint film showcases exceptional adhesion and surpasses ordinary paints in rust resistance, corrosion resistance, and weather resistance. This makes it ideal for applications requiring long-lasting protection and aesthetic appeal.
