Electrophoretic coating is a state-of-the-art technology where the painted object, acting as an anode, is immersed in water-soluble paint. A corresponding cathode is established, and a direct current is applied between the two, ensuring an even and flawless coat on the object through the physical and chemical interactions of the current.
The comprehensive process flow for electrophoretic coating on general metal surfaces is as follows: 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.
Electrophoretic coating encompasses four synchronized processes, ensuring a seamless and high-quality finish.
1. Electrophoresis: Under the influence of a DC electric field, colloidal particles charged either positively or negatively move towards the opposite charge, a phenomenon also termed 'swimming.'
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena respectively.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles near the anode release electrons and deposit in an insoluble state, forming a robust paint film through precipitation.
4. Electroosmosis: An electric field causes the liquid phase to move while the solid phase remains static. Electroosmosis gradually expels water from the paint film, creating a dense, highly resistant layer that even currents cannot penetrate.
5. Iron red epoxy electrophoresis paint example: Using modified epoxy resin, butanol, ethanol amine, talc, and iron red, this paint, when mixed with distilled water and subjected to a DC electric field, separates into positively and negatively charged ions. This initiates a series of complex physical, colloidal, and electrochemical processes.
The electrophoretic coating process is rapid and supports mechanized and automatic continuous operations, reducing labor intensity. It produces a uniform, smooth, and highly adhesive paint film even on hard-to-coat areas, such as welding seams.
Electrophoretic paint achieves a remarkable utilization rate of 90%-95%. Using water as a solvent, it boasts non-combustibility, non-toxicity, and user-friendly operation.
The cured paint film from electrophoresis exhibits superior adhesion and unparalleled rust, corrosion, and weather resistance compared to ordinary paints and traditional application methods.

Advantages of our Automatic Powder Spraying Equipment:
1. Utilizing our automatic powder spraying equipment not only reduces labor costs significantly but also ensures superior product quality and consistency. This facilitates the stable and efficient mass production required to meet the demands of modern enterprises.
2. Our spraying equipment operates without emitting irritating odors, thus preventing environmental pollution and safeguarding the physical and mental health of operators.
3. The first-time utilization rate of our automatic powder spraying equipment ranges between 70%-80%, with coating thicknesses of 60-150 microns. Moreover, the powder coating is recyclable, enabling a remarkable utilization rate of 90%-98%. This allows for a thicker coating with just one application.
4. The powder coatings used in our automatic powder coating equipment are entirely solvent-free, ensuring a safer and more environmentally friendly process.
5. Upon curing, the powder coatings exhibit high plumpness and soft hues. As these coatings are solvent-free, they minimize the formation of pinholes and bubbles during curing. Being solid coatings, they do not leak or evaporate during transportation, ensuring consistent quality.
