Electrophoretic coating is a cutting-edge technology where the object to be painted is immersed in water-soluble paint, acting as the anode in anodic electrophoresis. It involves setting up a corresponding cathode and passing a direct current between the two poles. This process ensures the paint coats the object evenly through the physical and chemical actions of the current.
The comprehensive 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 comprises four simultaneous, intricate processes.
1. Electrophoresis: Under a DC electric field, colloidal particles with positive and negative charges move towards the opposite charges, a phenomenon also known as swimming.
2. Electrolysis: Oxidation and reduction reactions occur on the electrodes, forming distinct oxidation and reduction phenomena.
3. Electrodeposition: Colloidal particles, charged due to electrophoresis, move towards the anode, releasing electrons and forming an insoluble paint film through deposition and precipitation.
4. Electroosmosis: The solid phase remains static, while the liquid phase moves under the electric field. This action expels water from the paint film, creating a dense paint film with high resistance and minimal water content.
5. Iron red epoxy electrophoresis paint: Utilizing modified epoxy resin, butanol, ethanol amine, talc, and iron red, this system undergoes a series of complex physical, chemical, colloid, and electrochemical changes under a DC electric field.
Electrophoretic coating offers rapid construction speed and facilitates mechanized, automated continuous operation. It reduces labor intensity, ensures uniform paint film, and achieves strong adhesion, even on difficult-to-coat areas like the welding seams of fascia plates, resulting in an even and smooth finish.
The paint utilization rate in electrophoretic coating is impressively high, ranging from 90%-95%. Since water is used as the solvent, the process is non-combustible, non-toxic, and user-friendly.
The paint film obtained after electrophoresis exhibits exceptional adhesion, superior rust resistance, corrosion resistance, and weather resistance compared to ordinary paints and conventional construction techniques.
