Electrophoretic coating represents a revolutionary coating technology. It involves immersing the object to be painted in a water-soluble paint solution as the anode (in anodic electrophoresis) while setting up a corresponding cathode. By passing a direct current between the two poles, the physical and chemical effects of the current ensure an even, smooth coating on the object.
The intricate process flow of electrophoretic coating on general metal surfaces is meticulously detailed 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 designed to achieve precision and perfection.
Electrophoretic coating encompasses four simultaneous, crucial processes that ensure optimal coating results.
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 respective electrodes, leading to oxidation and reduction phenomena at the electrodes.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles migrate towards the anode, release electrons, and deposit in an insoluble state, forming a paint film.
4. Electroosmosis: Under the electric field's action, the solid phase remains stationary while the liquid phase moves. This causes water within the paint film to be gradually expelled, forming a dense paint film with low water content and high resistance.
Taking iron red epoxy electrophoresis paint as an example: The electrophoresis paint system involves modified epoxy resin, butanol, ethanol amine, talc, and iron red substances. When mixed with distilled water and subjected to a DC electric field, it undergoes complex physical, chemical, colloid chemistry, and electrochemical changes.
The electrophoretic coating process is characterized by its rapid construction speed, enabling mechanized and automatic continuous operation. This method reduces labor intensity, ensures a uniform paint film with strong adhesion, and effectively coats even difficult-to-reach areas, such as welding seams on fascia plates.
With a paint utilization rate of 90%-95%, electrophoretic paint is highly efficient. Its use of water as a solvent makes it non-combustible, non-toxic, and easy to handle.
The dried paint film post-electrophoresis exhibits excellent adhesion, superior rust resistance, corrosion resistance, and weather resistance, outperforming ordinary paints and general construction methods.

Advantages of Automatic Powder Spraying Equipment.
1. Employing automatic powder spraying equipment not only drastically cuts labor costs but also significantly enhances product quality and consistency. This facilitates smooth, stable, and large-scale production, effectively addressing productivity challenges within enterprises.
2. During the spraying process, our automatic equipment generates no irritating odors, thus preventing environmental pollution and safeguarding the physical and mental well-being of operators.
3. Our automatic powder spraying equipment boasts an initial powder utilization rate of 70%-80%, with coating thicknesses ranging from 60-150 microns. Furthermore, its powder coating is recyclable, pushing the coating utilization rate to an impressive 90%-98%. A single application yields a thicker, more durable coating.
4. The powder coatings used by our automatic equipment are entirely solvent-free,
5. Once cured, the powder coating delivers a rich, smooth finish with soft colors. Its solvent-free composition prevents the formation of pinholes and bubbles during curing. As a solid coating, it remains intact with no leaks or evaporation during transportation.
