Electrophoretic coating is a revolutionary coating technology where the object to be painted is submerged in water-soluble paint, acting as the anode (anodic electrophoresis). A cathode is established, and by passing direct current between the two poles, an even paint layer is formed on the object due to the physical and chemical effects of the current.
The electrophoretic coating process for general metal surfaces follows these steps: 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 consists of four concurrent processes.
1. Electrophoresis: Under a DC electric field, colloidal particles charged positively or negatively migrate towards the opposite charge, a process also known as swimming.
2. Electrolysis: Redox reactions occur at the electrodes, resulting in oxidation and reduction phenomena.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles migrate towards the anode and release electrons, resulting in an insoluble state deposition. This leads to the formation of the paint film.
4. Electroosmosis: Here, the liquid phase moves while the solid phase remains stationary under the electric field. This process expels water from the paint film, forming a dense film with high resistance and low water content.
5. For instance, iron red epoxy electrophoresis paint involves a system modified with epoxy resin, butanol, ethanol amine, talc, and iron red substances. When mixed with distilled water and subjected to a DC electric field, it undergoes a series of complex physical, chemical, and electrochemical transformations.
Electrophoretic coating offers rapid construction speed and the potential for mechanized, continuous automatic operation, reducing labor intensity. It ensures uniform paint film, strong adhesion, and smooth coverage even in areas difficult to coat by conventional methods, such as weld seams.
The paint utilization rate reaches an impressive 90%-95%. Since electrophoretic paint uses water as a solvent, it boasts non-combustibility, non-toxicity, and ease of operation.
The paint film dried after electrophoresis exhibits exceptional adhesion, rust resistance, corrosion resistance, and weather resistance, surpassing ordinary paints and conventional construction methods.
