Electrophoretic coating is a revolutionary technology where the object to be painted is immersed in a water-soluble paint solution, serving as the anode in anodic electrophoresis. An opposing cathode is set up, and a direct current is passed between the two. This ingenious process causes the paint to be uniformly deposited on the object through the combined physical and chemical effects of the current.
The meticulous process flow for electrophoretic coating on general metal surfaces is outlined 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. Each step ensures superior coating adherence and quality.
Electrophoretic coating is a complex procedure that encompasses four concurrent processes, each contributing to its effectiveness and efficiency.
1. Electrophoresis: Under the influence of a direct current electric field, positively and negatively charged colloidal particles migrate towards the oppositely charged electrodes, a phenomenon often referred to as 'swimming.'
2. Electrolysis: This involves redox reactions occurring at the electrodes, where oxidation and reduction phenomena are distinctly observed.
3. Electrodeposition: As a result of electrophoresis, charged colloidal particles move towards the anode. Upon reaching the template surface, these particles release electrons, deposit in an insoluble state, and precipitate to form a robust paint film.
4. Electroosmosis: Here, under the influence of an electric field, the solid phase remains static while the liquid phase moves. Electroosmosis gradually expels water from the paint film, resulting in a dense, highly resistant film with minimal water content, impeding further current passage.
5. Taking Iron Red Epoxy Electrophoresis Paint as an example: The paint system is composed of modified epoxy resin, butanol, ethanolamine, talc, and iron red substances. When mixed with distilled water and subjected to a direct current electric field, it separates into positively charged cations and negatively charged anions, undergoing a series of complex physico-chemical, colloid-chemical, and electrochemical transformations.
The construction speed of electrophoretic coating is impressively swift, facilitating mechanized and automated continuous operation. This reduces labor intensity while yielding a uniform, strongly adherent paint film. Even parts that are typically challenging to coat, such as the welding seams of fascia plates, receive an even and smooth finish.
With an astonishing paint utilization rate of 90%-95%, electrophoretic paint is both non-combustible and non-toxic, using water as a solvent. This not only simplifies operation but also prioritizes safety and environmental friendliness.
Once dried, the electrophoretically applied paint film exhibits superior adhesion. Its resistance to rust, corrosion, and adverse weather conditions outshines that of ordinary paints and conventional construction methods, ensuring long-lasting protection and elegance.
