Electrophoretic coating technology involves immersing the object in a water-soluble paint bath, establishing it as the anode (anodic electrophoresis) while setting up a corresponding cathode, and passing a direct current between these poles. The resultant physical and chemical effects of the current ensure an even, flawless coat on the object.
The detailed process flow of 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 on the tank → Ultra-filtration → Drying → Off-line.
Electrophoretic coating generally comprises four concurrent processes that work in synergy.
1. Electrophoresis: Driven by a DC electric field, positively and negatively charged colloidal particles migrate in opposite directions. This movement is also known as swimming.
2. Electrolysis: Redox reactions occur on the electrodes, resulting in oxidation and reduction phenomena respectively at the electrodes.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles migrate towards the anode, releasing electrons and depositing in an insoluble state on the template surface, forming a paint film.
4. Electroosmosis: Under the electric field's action, the solid phase remains stationary while the liquid phase moves. This process gradually expels water from the paint film, resulting in a nearly impermeable, tightly packed paint film with high resistance.
5. Iron red epoxy electrophoresis paint: Composed of modified epoxy resin, butanol, ethanol amine, talc, and iron red substance, this paint system undergoes a complex array of physical, chemical, colloidal, and electrochemical changes under a DC electric field, resulting in positively charged cations and negatively charged anions.
Electrophoretic coating offers rapid construction speeds and facilitates mechanized, automatic continuous operations. This reduces labor intensity and produces a uniform, strong adhesion paint film. It can seamlessly coat hard-to-reach areas like the welding seams of fascia plates, ensuring an even and smooth finish.
The efficiency of paint utilization is remarkably high, ranging from 90%-95%. Utilizing water as the solvent, electrophoretic paint is non-combustible, non-toxic, and easy to handle, enhancing operational safety and convenience.
The dried paint film post-electrophoresis boasts superior adhesion and significantly enhanced rust resistance, corrosion resistance, and weather resistance compared to regular paints and conventional coating methods.
