Electrophoretic coating is a cutting-edge coating technology where the painted object, serving as the anode in anodic electrophoresis, is immersed in a water-soluble paint. A corresponding cathode is set up, and a direct current is passed between the two poles, ensuring the paint is distributed evenly over the object through the marvels of both physical and chemical interactions of the current.
The meticulous process flow for 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 in the tank → Ultra-filtration → Drying → Off-line.
Electrophoretic coating encompasses four concurrent processes.
1. Electrophoresis: Under the influence of a DC electric field, positively and negatively charged colloidal particles move towards the negative and positive direction, a process also known as swimming.
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena at these points.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles move to the anode, release electrons, and deposit in an insoluble state, forming a paint film.
4. Electroosmosis: Under an electric field, the solid phase remains stationary while the liquid phase moves. This process gradually expels water from the paint film, forming a dense, highly resistant coating that water or even current can barely penetrate.
5. Iron Red Epoxy Electrophoresis Paint: This system involves modified epoxy resin, butanol, ethanolamine, talc, iron red substance, mixed with distilled water. Under a DC electric field, the system separates into positively charged cations and negatively charged anions, resulting in a complex series of physical, chemical, and electrochemical transformations.
Electrophoretic coating offers rapid construction speeds, enabling mechanized and automatic continuous operations that reduce labor intensity. It ensures a uniform, strong adhesion paint film, even on hard-to-coat parts like fascia plate welding seams, which traditional methods struggle with.
The paint utilization rate in electrophoretic coating reaches an impressive 90%-95%. Using water as a solvent, this method boasts non-combustibility, non-toxicity, and ease of operation.
The dried paint film post-electrophoresis features superb adhesion, with rust, corrosion, and weather resistance surpassing that of ordinary paints and conventional construction methods.
