Electrophoretic coating is an advanced technology where the object is immersed in water-soluble paint, acting as the anode (anodic electrophoresis), with a cathode set up in opposition. Direct current flows between the two poles, resulting in a uniform, high-quality coating through the physical and chemical interactions of the current.
The meticulous process flow for electrophoretic coating on metal surfaces includes: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → In-tank cleaning → Ultra-filtration → Drying → Off-line.
Electrophoretic coating encompasses four concurrent processes.
1. Electrophoresis: In the DC electric field, charged colloidal particles migrate towards opposite charges, a movement also known as 'swimming.'
2. Electrolysis: At the electrodes, redox reactions occur, leading to oxidation and reduction phenomena.
3. Electrodeposition: Charged colloidal particles, driven by electrophoresis, release electrons upon nearing the anode, resulting in the formation of an insoluble paint film on the template surface.
4. Electroosmosis: The liquid phase moves under the electric field's influence, expelling water from the paint film, culminating in a dense, highly resistant coating almost impervious to current.
5. For example, iron red epoxy electrophoresis paint consists of modified epoxy resin, butanol, ethanol amine, talc, and iron red. When mixed with distilled water and subjected to a DC electric field, it separates into charged ions, undergoing a series of intricate physical, chemical, and electrochemical changes.
Electrophoretic coating offers rapid application, enabling mechanized and automated continuous operation, thus reducing labor intensity. It ensures uniform paint films with strong adhesion, even on hard-to-coat areas like weld seams.
With a paint utilization rate of 90%-95%, electrophoretic coating employs water as the solvent, ensuring non-combustibility, non-toxicity, and ease of use.
Paint films dried post-electrophoresis exhibit excellent adhesion and superior rust, corrosion, and weather resistance compared to conventional paints and application methods.
