Coating Electrophoresis Line

As the professional manufacturer, Qingguo Intelligent would like to provide you high quality coating electrophoresis line. The following are the main aspects of the coating electrophoresis line, including its working principle, main components, and advantages.

Working principle of coating electrophoresis line

The basic principle of electrophoretic coating is to use electric current to move charged coating particles towards the surface of the workpiece in the electrolyte, forming a coating.

The workflow is as follows:

1. Preparation of electrophoretic coatings: Prepare suitable water-based coatings, usually containing resins, pigments, and additives.

2. Pre treatment: Clean, remove oil, rust, and phosphating the workpiece to lay a foundation for painting.

3. Electrophoretic coating:

-Immerse the workpiece into an electrophoresis tank containing cleaned electrophoretic coating.

-After being powered on, positively charged paint particles will move towards the negatively charged surface of the workpiece and deposit.

4. Rinse and dry:

-Rinse the workpiece with water to remove any unattached paint.

-After drying and curing treatment, the durability and adhesion of the coating are improved.

5. Post treatment (optional): Additional coatings or protective treatments can be applied, such as varnish spraying.

The main components of the coating electrophoresis line

1. Pre treatment equipment: including cleaning, degreasing, rust removal, and phosphating equipment to ensure a smooth surface of the workpiece.

2. Electrophoretic tank: A tank for holding electrophoretic coatings, equipped with heating and stirring devices to maintain uniformity of the coating.

3. Power supply device: Provides stable voltage and current to enable coating particles to effectively deposit on the surface of the workpiece.

4. Water washing device: used to wash workpieces and remove excess paint.

5. Drying and curing oven: Heating equipment acts on the coating for curing, ensuring coating performance.

6. Control system: used to monitor and adjust various parameters during the painting process, improve production efficiency and product quality.

Application advantages of coating electrophoresis line

1. Efficient anti-corrosion: Electrophoretic coating can provide a uniform and dense coating, effectively resisting oxidation and corrosion.

2. Environmental friendliness: Use water-based coatings to reduce the emission of volatile organic compounds (VOCs) and comply with modern environmental standards.

3. Uniform coating: Suitable for workpieces with complex shapes, ensuring uniform coating coverage, especially in grooves and hard to reach areas.

4. Cost savings: The electrophoresis process reduces material waste as excess paint can be collected and reused.

5. Improve adhesion: The curing of electrophoretic coatings helps to enhance the adhesion between the coating and the substrate, reducing the risk of detachment.

6. High degree of automation: Electrophoresis lines usually achieve high automation, improve production efficiency, and reduce labor costs.

Application fields of coating electrophoresis line

Coating electrophoresis lines are widely used in:

-Automobile manufacturing: anti-corrosion treatment of body, chassis, wheels and other components.

-Home appliance industry: Coating of metal casings for refrigerators, washing machines, and other devices.

-Electronic products: Metal casings and frames are protected against corrosion.

-Aerospace: Surface treatment of aircraft components and other aircraft.
