Electrophoretic coating is an innovative and efficient coating technology where the painted object acts as the anode (anodic electrophoresis), immersed in water-soluble paint, and a corresponding cathode is established. By passing a direct current between these two poles, the paint is uniformly distributed over the object's surface through the physical and chemical effects of the current, ensuring a smooth and even finish.
The comprehensive process flow of electrophoretic coating on general metal surfaces includes several meticulous 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. Each step is designed to enhance the coating's quality and durability.
Electrophoretic coating is a multifaceted process that generally encompasses four simultaneous and integral stages.
1. Electrophoresis: Under the influence of a DC electric field, the charged colloidal particles move towards the oppositely charged electrode, a process also referred to as swimming, ensuring even particle distribution.
2. Electrolysis: Redox reactions take place on the electrodes, leading to oxidation and reduction phenomena that contribute to the overall effectiveness of the coating process.
3. Electrodeposition: As a result of electrophoresis, charged colloidal particles near the anode release electrons and deposit in an insoluble state, forming a stable and uniform paint film on the object's surface.
4. Electroosmosis: In the electric field, while the solid phase remains stationary, the liquid phase moves. This movement helps expel water from the paint film, resulting in a densely packed coating with low water content and high resistance, effectively preventing further current passage.
5. Iron Red Epoxy Electrophoresis Paint: Using a modified epoxy resin system that includes butanol, ethanolamine, talc, and iron red substances, this process, under a DC electric field, separates into positively charged cations and negatively charged anions, initiating a series of intricate physical, chemical, and electrochemical changes to form a robust coating.
The rapid construction speed of electrophoretic coating enables mechanized and automated continuous operations. This reduces labor intensity while ensuring a uniform, strong adhesion paint film. It can deliver a smooth finish on challenging surfaces, such as the welding seams of fascia plates, where general methods fail.
Electrophoretic paint boasts a high utilization rate of 90%-95%. Using water as a solvent, it offers non-combustibility, non-toxicity, and ease of operation, enhancing both safety and efficiency.
The dried paint film after electrophoresis exhibits exceptional adhesion with superior rust, corrosion, and weather resistance, outperforming ordinary paints and conventional construction methods.
