Electrophoretic coating is a state-of-the-art painting technology where the object to be coated is immersed in a water-soluble paint acting as the anode (anodic electrophoresis) with an opposing cathode. Direct current is then applied between these electrodes, causing the paint to uniformly coat the object through the intricate interplay of physical and chemical effects of the current.
The meticulous process flow for electrophoretic coating on general metal surfaces includes: 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.
The electrophoretic coating process typically encompasses four simultaneous stages:
1. Electrophoresis: Under the influence of a DC electric field, charged colloidal particles migrate towards their respective opposite charges, a phenomenon also known as 'swimming.'
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena at these points.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles near the anode release electrons and deposit as an insoluble film, forming the paint layer.
4. Electroosmosis: In an electric field, the liquid phase moves while the solid phase remains stationary. This process expels water from the paint film, resulting in a dense, high-resistance coating almost impermeable to current.
5. For instance, iron red epoxy electrophoresis paint involves a system comprising modified epoxy resin, butanol, ethanolamine, talc, and iron red compounds. When mixed with distilled water and subjected to a DC electric field, it separates into positively charged cations and negatively charged anions, undergoing complex physical, chemical, and electrochemical transformations.
Electrophoretic coating boasts rapid construction speed, enabling mechanized and automatic continuous operation, thus reducing labor intensity. It yields a uniform, adhesive paint film, even on challenging surfaces like the welding seams of fascia plates, which are typically difficult to coat using conventional methods.
With a paint utilization rate of 90%-95%, and water as the solvent, electrophoretic paint offers advantages of non-combustibility, non-toxicity, and ease of application.
The cured paint film from electrophoresis exhibits excellent adhesion, offering superior rust resistance, corrosion resistance, and weatherability compared to ordinary paints and conventional construction methods.
