Electrophoretic coating represents an advanced technology where the object to be painted is immersed in water-based paint, acting as the anode (anodic electrophoresis). A corresponding cathode is introduced, and a direct current flows between these poles, ensuring an even and smooth paint distribution through the combined physical and chemical effects of the current.
The electrophoretic coating process on standard metal surfaces involves a comprehensive series of steps: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → In-tank cleaning → Ultra-filtration → Drying → Off-line.
Electrophoretic coating comprises four simultaneous and intricate processes that work in harmony.
1. Electrophoresis: Under a DC electric field, positively and negatively charged colloidal particles migrate towards the negative and positive electrodes, a dynamic movement also referred to as swimming.
2. Electrolysis: At the electrodes, redox reactions take place, resulting in oxidation and reduction phenomena, essential for the coating process.
3. Electrodeposition: During electrophoresis, charged colloidal particles move toward the anode. Here, they release electrons and form an insoluble deposit, creating a robust paint film on the template surface.
4. Electroosmosis: While the solid phase remains stationary, the liquid phase moves under the electric field. This process gradually expels water from the paint film, eventually forming a dense, highly resistant film that even current cannot penetrate.
5. Using iron red epoxy electrophoresis paint as an example: This system includes modified epoxy resin, butanol, ethanolamine, talc, and iron red substances. When mixed with distilled water and exposed to a DC electric field, it undergoes complex colloidal, electrochemical, and physical transformations, separating into charged cations and anions.
Electrophoretic coating boasts a swift construction speed and supports mechanized, automated, continuous operations, significantly reducing labor intensity. It produces a uniform paint film with strong adhesion, ensuring even coverage on hard-to-coat areas, such as the seams of fascia plates.
The paint utilization rate is exceptionally high, ranging from 90% to 95%. Using water as a solvent, electrophoretic paint is non-combustible, non-toxic, and easy to handle, offering additional safety and environmental benefits.
The dried paint film after electrophoresis exhibits outstanding adhesion properties, with superior rust, corrosion, and weather resistance compared to ordinary paints and conventional application methods.

Advantages of Automatic Powder Spraying Equipment
1. Our automatic powder spraying equipment not only reduces labor costs but also significantly enhances product quality, ensuring stability in large-scale production and effectively addressing productivity challenges.
2. During the spraying process, our automatic equipment generates no irritating odors, preventing environmental pollution and protecting the operator's health.
3. The first-time utilization rate of powder spraying with our automatic equipment reaches 70%-80%, with coating thicknesses ranging from 60-150 microns. Additionally, the powder can be recycled, leading to an overall coating utilization rate of 90%-98%. A single application can achieve a thicker coating.
4. Our automatic powder coating equipment's powder coating is free from solvents.
5. Post-curing, the powder coating exhibits high plumpness and smooth color. Since it is solvent-free, it avoids pinholes and bubbles during curing. As a solid coating, it does not leak or evaporate during transportation.
