Electrophoretic coating is an advanced coating technology wherein the object to be painted is immersed in a water-soluble paint bath, acting as the anode in anodic electrophoresis. A corresponding cathode is established, and a direct current is applied between the two electrodes. This current facilitates a uniform coating on the object through the physical and chemical interactions induced by the electrical field.
The comprehensive 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 on the tank → Ultra-filtration → Drying → Off-line.
Electrophoretic coating involves four simultaneous, intricate processes.
1. Electrophoresis: Under the influence of a DC electric field, positively and negatively charged colloidal particles migrate towards the negative and positive electrodes respectively, a process also known as swimming.
2. Electrolysis: This involves redox reactions on the electrodes, resulting in oxidation and reduction phenomena on the respective electrodes.
3. Electrodeposition: Driven by electrophoresis, charged colloidal particles move toward the anode, releasing electrons and depositing in an insoluble state on the template surface, forming a paint film.
4. Electroosmosis: Here, the solid phase remains stationary while the liquid phase moves under the electric field. This movement expels water from the paint film, ultimately forming a highly resistant, dense paint film with minimal water content.
5. For instance, Iron red epoxy electrophoresis paint involves an electrophoresis paint system that includes modified epoxy resin, butanol, ethanol amine, talc, and iron red components. Mixed with distilled water and subjected to a DC electric field, this system undergoes separation into positively charged cations and negatively charged anions, followed by a series of complex physical, chemical, and electrochemical transformations.
Electrophoretic coating offers rapid construction speeds, enabling mechanized and automated continuous operations that lower labor intensity. It ensures a uniform paint film with strong adhesion, achieving smooth and even coverage even on challenging parts such as welding seams of fascia plates.
The paint utilization rate is impressively high at 90%-95%. Electrophoretic paint, utilizing water as a solvent, boasts advantages like non-combustibility, non-toxicity, and ease of operation.
The paint film dried post-electrophoresis exhibits excellent adhesion. Its resistance to rust, corrosion, and adverse weather conditions surpasses that of ordinary paints and conventional construction methods.
