Electrophoretic coating is an innovative technology where the object to be painted is immersed in a water-soluble paint solution as the anode (anodic electrophoresis) and paired with a corresponding cathode. By applying a direct current between these two poles, the paint is uniformly coated across the object, thanks to the intricate interplay of physical and chemical effects induced by the current.
The streamlined process flow of electrophoretic coating on general metal surfaces is meticulously designed as follows: Pre-cleaning → On-line → Oil removal → Washing → Rust removal → Washing → Neutralization → Washing → Phosphating → Washing → Passivation → Electrophoretic coating → Cleaning in the tank → Ultra-filtration → Drying → Off-line.
Electrophoretic coating encompasses four concurrent, sophisticated processes.
1. Electrophoresis: Under the influence of a DC electric field, positively and negatively charged colloidal particles migrate towards the opposite poles, a process also known as swimming.
2. Electrolysis: Redox reactions occur at the electrodes, leading to distinct oxidation and reduction phenomena at each electrode.
3. Electrodeposition: Through electrophoresis, charged colloidal particles migrate towards the anode, where they release electrons and deposit insolubly on the template surface, resulting in the formation of a paint film.
4. Electroosmosis: Driven by the electric field, the liquid phase moves while the solid phase remains stationary. This action expels water from the paint film, ultimately creating a dense film with low water content and high resistance, impeding even the passage of current.
5. For instance, iron red epoxy electrophoresis paint: This system employs modified epoxy resin, butanol, ethanolamine, talc, and iron red substances. Mixed with distilled water, the paint undergoes a series of complex physical, chemical, colloidal, and electrochemical transformations under a DC electric field, separating into positively charged cations and negatively charged anions.
Electrophoretic coating boasts a rapid construction speed, facilitating mechanized and automatic continuous operation, which reduces labor intensity. It ensures a uniform paint film with strong adhesion, even on parts that are challenging to coat with conventional methods, such as the welding seams of fascia plates.
Remarkably efficient, electrophoretic paint has a utilization rate of 90%-95%. Using water as a solvent, it offers the advantages of being non-combustible, non-toxic, and easy to handle.
The dried electrophoretic paint film exhibits superb adhesion and superior rust resistance, corrosion resistance, and weather resistance, outperforming ordinary paints and general construction methods.

Advantages of Automatic Powder Spraying Equipment
1. By utilizing automatic powder spraying equipment, not only are labor costs reduced, but product quality is significantly enhanced and stabilized, facilitating smooth, large-scale production and addressing productivity challenges.
2. During the spraying process, automatic equipment emits no irritating odors, preventing environmental pollution and safeguarding the health of operators.
3. Automatic powder spraying equipment achieves a first-time powder utilization rate of 70%-80%, with coating thicknesses ranging from 60-150 microns. The powder can be recycled, pushing utilization rates to 90%-98%, ensuring a thicker, more durable coating in a single application.
4. The powder used in automatic powder coating equipment contains no solvents, making it environmentally friendly and safe.
5. Once cured, the powder coating offers high fullness and a soft color. Since it contains no solvents, it avoids pinholes and bubbles during curing, and being a solid coating, it neither leaks nor evaporates during transport.
