Electrophoretic coating is an innovative technology where the object to be painted is immersed in water-soluble paint, acting as the anode in anodic electrophoresis. A corresponding cathode is established, and direct current is passed between these two poles. Through the physical and chemical effects of the current, the paint is uniformly distributed over the object, ensuring a flawless finish.
The process flow for applying electrophoretic coating on a typical metal surface is meticulously detailed as follows: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Tank cleaning → Ultra-filtration → Drying → Off-line. This systematic approach ensures optimal coating quality.
The electrophoretic coating procedure comprises four concurrent processes, each crucial to achieving an impeccable finish.
1. Electrophoresis: In this phase, under the influence of a DC electric field, positively and negatively charged colloidal particles migrate towards the respective opposite charges, also referred to as 'swimming.'
2. Electrolysis: This involves redox reactions occurring at the electrodes, leading to oxidation at one electrode and reduction at the other, forming the basis of the coating process.
3. Electrodeposition: Due to electrophoresis, charged colloidal particles move towards the anode, releasing electrons at the template surface. This results in the formation of an insoluble, precipitated paint film, marking the deposition phase.
4. Electroosmosis: Under the electric field, solid phase remains stationary while the liquid phase moves. This movement expels water from the paint film, culminating in a dense, high-resistance paint film with minimal water content.
5. Take iron red epoxy electrophoresis paint as an example: The system utilizes modified epoxy resin, butanol, ethanolamine, talc, and iron red. When mixed with distilled water and subjected to a DC electric field, it separates into positively and negatively charged ions, undergoing complex physical, chemical, and electrochemical transformations.
Electrophoretic coating boasts rapid construction speed and enables mechanized, automatic continuous operation. This reduces labor intensity while ensuring a uniform, strong adhesive paint film. It can achieve even and smooth coverage on challenging parts, such as the welding seams of fascia plates, where traditional methods might fail.
With a paint utilization rate of 90%-95%, electrophoretic paint's water-based solvent offers non-combustibility, non-toxicity, and ease of operation, making it an environmentally friendly choice.
After drying, the electrophoresis-derived paint film exhibits superior adhesion, rust resistance, corrosion resistance, and weather resistance compared to conventional paints and application methods.
