Electrophoresis Coating Line

Qingguo Intelligent is China manufacturer and supplier who mainly produces electrophoresis coating line with many years of experience. Electrophoresis coating line is an efficient coating production line widely used for metal surface treatment in industries such as automobiles, home appliances, and hardware. Provide a detailed introduction to the definition, working principle, components, and performance characteristics of electrophoresis coating line.

1.Definition

Electrophoresis coating line is a coating production line that immerses the coated material in water-soluble paint (electrophoresis paint) and uniformly applies the paint on the surface of the coated material through the action of direct current. Electrophoresis coating technology combines electrochemical and physicochemical principles to achieve efficient and uniform coating effects.

2.Working principle

The working principle of electrophoresis coating line is based on the phenomenon of electrophoresis . During the painting process, the object being coated serves as the anode (or cathode), while the other pole serves as the cathode (or anode), with direct current flowing between the two poles. Due to the directional movement of charged particles in electrophoresis paint under the action of an electric field, the coating is uniformly deposited on the surface of the coated material, forming a dense coating film.

3.Components

The electrophoresis coating line usually consists of the following main parts:

Pre treatment equipment: including pre cleaning, oil removal, water washing, rust removal, neutralization, phosphating and other processes, used to remove oil stains, rust and other impurities on the surface of the coated material, and improve the adhesion of the coating film.

Electrophoresis tank: A mixture of electrophoresis paint and distilled water, which is the core part of electrophoresis  coating. The coated material is obtained by electrophoresis in this tank to obtain a coating film.

Ultrafiltration system: used to control the concentration of impurity ions in the tank solution to ensure coating quality.

Drying equipment: such as an oven, used to dry and solidify the wet coating film after electrophoresis, forming a hard coating.

Control system: including power supply, temperature control system, etc., used to monitor and adjust various parameters during the painting process.

4.Performance characteristics

High coating efficiency: Electrophoresis coating can achieve automated continuous operation, greatly improving coating efficiency.

Uniform coating: The Electrophoresis effect allows the coating to deposit evenly on the surface of the object being coated, forming a smooth and dense coating.

Strong adhesion: After electrophoresis coating treatment, the coating is tightly bonded to the surface of the coated object, with strong adhesion.

Good corrosion resistance: The coating formed by the drying and curing of electrophoresis paint has good corrosion resistance.

Good environmental friendliness: electrophoresis coating uses water as a solvent, which is non flammable, non-toxic, and pollution-free, meeting environmental requirements.

5.Precautions for use

Regular maintenance of equipment: Ensure the normal operation and coating quality of the electrophoresis coating line.

Strictly control coating parameters such as voltage, current density, and bath temperature to achieve the best coating effect.

Pay attention to safety production: Electrical equipment and chemicals are involved in the electrophoresis coating process, and safety production regulations must be strictly followed.
