Electrophoretic coating represents 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. By applying a direct current between these two poles, the paint is uniformly distributed over the object through the combined physical and chemical effects of the current, ensuring a seamless and durable finish.
The comprehensive process flow for applying electrophoretic coating to general metal surfaces includes several meticulous steps: 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. Each step is vital for achieving a premium, resilient coating.
The intricacies of electrophoretic coating encompass four concurrent processes, each crucial for producing a high-quality finish.
1. Electrophoresis: Within a DC electric field, colloidal particles charged positively and negatively migrate towards the negative and positive electrodes, respectively, a movement aptly termed as 'swimming.'
2. Electrolysis: Electrodes undergo redox reactions, leading to oxidation and reduction phenomena at each electrode, essential for the coating formation.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles move to the anode, releasing electrons upon reaching the template surface, resulting in an insoluble deposition. This critical stage is when the paint film begins to form, ensuring durable adhesion.
4. Electroosmosis: In an electric field, while the solid phase remains static, the liquid phase moves. Electroosmosis expels water from the paint film, creating a dense film with minimal water content, high resistance, and uniform thickness, even impeding current passage.
For instance, iron red epoxy electrophoresis paint involves a complex system of modified epoxy resin, butanol, ethanol amine, talc, and iron red components. Mixed with distilled water and subjected to a DC electric field, this system undergoes a series of intricate physical, chemical, and electrochemical transformations, resulting in a robust and even coating.
Electrophoretic coating boasts rapid construction speed, enabling mechanization and continuous automatic operation. This efficiency reduces labor intensity and ensures a uniform paint film with robust adhesion. Even challenging areas, such as the welding seam of a fascia plate, benefit from an even, smooth coating not achievable by conventional methods.
With a paint utilization rate of 90%-95%, electrophoretic paint, which uses water as a solvent, offers non-combustible, non-toxic, and user-friendly advantages. Its high efficiency and safety make it an ideal choice for various applications.
The dried paint film post-electrophoresis demonstrates exceptional adhesion, with superior rust resistance, corrosion resistance, and weatherability compared to conventional paints and typical construction methods. This ensures a long-lasting, high-quality finish for your products.
