Electrophoretic coating is a cutting-edge technology where the object to be coated is immersed in water-soluble paint, acting as the anode in anodic electrophoresis, with a corresponding cathode set up. A direct current is then passed between the two poles, resulting in a uniform paint layer on the object through the electrochemical and physical effects of the current.
The streamlined process flow for applying electrophoretic coating on metal surfaces is meticulously detailed as follows: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Tank cleaning → Ultra-filtration → Drying → Off-line.
Electrophoretic coating encompasses four concurrent processes, each pivotal to achieving a flawless finish.
1. Electrophoresis: Under the influence of a DC electric field, colloidal particles charged positively or negatively migrate towards the oppositely charged electrode, a phenomenon also known as 'swimming.'
2. Electrolysis: This process involves redox reactions occurring at the electrodes, resulting in distinct oxidation and reduction phenomena.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles move towards the anode, releasing electrons and depositing in an insoluble state to form the paint film.
4. Electroosmosis: Under an electric field, while the solid phase remains stationary, the liquid phase moves. This movement expels water from the paint film, culminating in a dense, high-resistance paint film with minimal water content.
5. As exemplified by iron red epoxy electrophoresis paint: The system involves the modified epoxy resin, butanol, ethanolamine, talc, and iron red substances. Mixed with distilled water, electrophoresis under a DC electric field separates it into positively charged cations and negatively charged anions, undergoing a series of complex physical, chemical, and electrochemical transformations.
Electrophoretic coating boasts rapid construction speed, enabling mechanized and automated continuous operation. This reduces labor intensity and ensures a uniform, strongly adhesive paint film, even on challenging surfaces like the welding seam of the fascia plate.
With a paint utilization rate soaring to 90%-95%, electrophoretic paint, using water as a solvent, offers non-combustibility, non-toxicity, and ease of operation.
The paint film produced post-electrophoresis boasts superior adhesion, with enhanced rust resistance, corrosion resistance, and weather resistance, outperforming ordinary paints and general construction methods.

Advantages of Automatic Powder Spraying Equipment.
1. Automatic powder spraying equipment not only cuts labor costs but also markedly enhances product quality and consistency. It ensures stable, high-volume production, effectively addressing productivity shortfalls.
2. During operation, automatic spraying equipment emits no irritating odors, safeguarding both the environment and the health of operators.
3. First-time powder spraying efficiency with automatic equipment ranges from 70%-80%, with coating thicknesses between 60-150 microns. Additionally, the powder can be recycled, pushing coating utilization rates to an impressive 90%-98%. A single application can achieve substantial coating thickness.
4. The powder coatings used in automatic powder coating systems are solvent-free, promoting safer operations.
5. Once cured, the powder coating from automatic spraying equipment exhibits high fullness and vibrant color. The absence of solvents prevents the formation of pinholes and bubbles during curing. As a solid coating, it remains stable without leaks or evaporation during transport.
