Electrophoretic coating is a revolutionary technology where the object to be painted is immersed in a water-soluble paint bath, acting as the anode in an anodic electrophoresis setup. A cathode is positioned accordingly, and when direct current flows between the two poles, the paint is uniformly deposited on the object through the intricate interplay of physical and chemical reactions induced by the electric current.
The meticulous process flow for electrophoretic coating on metal surfaces is outlined as follows: Pre-cleaning → On-line → Oil Removal → Washing → Rust Removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic Coating → Rinsing in the Tank → Ultra-filtration → Drying → Off-line. This sequence ensures optimal surface preparation and coating integrity.
Electrophoretic coating encompasses four simultaneous and interdependent processes, each contributing to the formation of a high-quality, durable paint film.
1. Electrophoresis: Under the influence of a DC electric field, charged colloidal particles migrate towards oppositely charged electrodes, a phenomenon akin to swimming.
2. Electrolysis: Redox reactions occur on the electrodes, resulting in oxidation and reduction phenomena that facilitate the coating process.
3. Electrodeposition: Charged colloidal particles are driven towards the anode, where they release electrons and precipitate in an insoluble state, thus forming a uniform paint film.
4. Electroosmosis: While the solid phase remains stationary under the electric field, the liquid phase moves. This process expels water from the paint film, leading to a highly dense, non-conductive coating with minimal water content.
5. Iron Red Epoxy Electrophoresis Paint Example: This system utilizes modified epoxy resin, butanol, ethanol amine, talc, and iron red components. When mixed with distilled water and subjected to a DC electric field, the paint undergoes complex physical, chemical, and electrochemical transformations, resulting in a robust coating.
The construction speed of electrophoretic coating is remarkably swift, enabling mechanized and automated continuous operations. This reduces labor intensity and produces a uniform, smooth paint film with strong adhesion, even on challenging surfaces such as weld seams.
The paint utilization rate is exceptionally high, ranging from 90% to 95%. Using water as a solvent, electrophoretic paint offers benefits like non-combustibility, non-toxicity, and straightforward operation.
The dried paint film formed after electrophoresis boasts excellent adhesion, superior rust resistance, corrosion resistance, and weather resistance, outperforming ordinary paints and traditional application methods.
