Electrophoretic coating is a state-of-the-art technology where the object to be painted is submerged in water-soluble paint as the anode (anodic electrophoresis) and a corresponding cathode is established. A direct current passes between these points, ensuring the paint is uniformly distributed on the object through the combined physical and chemical action of the current.
The seamless process flow for electrophoretic coating on general metal surfaces is meticulously structured 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.
Electrophoretic coating encompasses four synchronized processes, ensuring optimal coating results.
1. Electrophoresis: In the presence of a DC electric field, positively and negatively charged colloidal particles migrate in opposite directions, a process also referred to as swimming.
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena.
3. Electrodeposition: Through electrophoresis, charged colloidal particles move to the anode near the template surface, releasing electrons and depositing in an insoluble state, forming a paint film.
4. Electroosmosis: Under an electric field, the liquid phase moves while the solid phase remains stationary, gradually expelling water from the paint film until it becomes dense, highly resistant, and almost impervious to current.
5. For instance, iron red epoxy electrophoretic paint is composed of modified epoxy resin, butanol, ethanol amine, talc, and iron red. When mixed with distilled water and subjected to a DC electric field, it separates into charged ions, undergoing complex physicochemical and electrochemical transformations.
Electrophoretic coating offers swift construction speed, enabling mechanized and automated continuous operation. This reduces labor intensity and ensures a uniform, strong, and smooth paint film, even on challenging surfaces like weld seams of fascia plates.
The paint utilization rate is remarkably high at 90%-95%, and since water is used as the solvent, the process boasts non-combustibility, non-toxicity, and ease of operation.
Post-electrophoresis, the dried paint film exhibits exceptional adhesion, rust resistance, corrosion resistance, and weather resistance, surpassing the performance of ordinary paints and traditional construction methods.
