Detailed explanation of electrophoretic paint process operation process

　　Electrophoretic painting technology is an advanced coating technology widely used in the metal surface treatment of industries such as automobiles, household appliances, hardware, and more. With its characteristics of high efficiency, environmental protection, and energy conservation, it has gradually replaced traditional spray painting processes. This article will provide a detailed introduction to the operation process of electrophoretic painting.

　　1. Preliminary Preparation

　　Surface Treatment: First, clean, degrease, and derust the metal surface to ensure it is clean and free of impurities.

　　Phosphating Treatment: Increase the activity and adhesion of the metal surface through phosphating treatment, providing a good foundation for subsequent electrophoretic paint coating.

　　2. Electrophoretic Paint Coating

　　Preparation of Electrophoresis Tank: Pour the electrophoretic paint into the electrophoresis tank and adjust the concentration, temperature, and pH of the electrophoretic paint according to product requirements.

　　Immersion of Metal Parts: Dip the pretreated metal parts into the electrophoresis tank, ensuring that the metal parts are completely immersed in the electrophoretic paint.

　　Electrophoresis: Apply electricity to cause the resin particles in the electrophoretic paint to deposit on the metal surface under the action of an electric field, forming a uniform and dense paint film.

　　3. Post-treatment

　　Rinsing: Remove the metal parts from the electrophoresis tank, rinse off the residual electrophoretic paint on the surface with water.

　　Drying: Place the metal parts in a drying chamber and heat them to cure the paint film, improving its adhesion and corrosion resistance.

　　4. Quality Inspection

　　Conduct quality inspections on the coated products, including visual inspections, thickness measurements, adhesion tests, etc., to ensure that the product quality meets the requirements.

　　5. Precautions

　　Operating Environment: Keep the operating environment clean to avoid dust, impurities, and other contaminants from affecting the electrophoretic paint.

　　Equipment Maintenance: Regularly inspect and maintain equipment such as the electrophoresis tank and power supply to ensure their normal operation.

　　Safety Precautions: Wear protective eyewear, gloves, and other protective equipment during operation to avoid contact of the electrophoretic paint with skin and eyes.

　　6. Conclusion

　　Electrophoretic painting technology has been widely used in metal surface treatment due to its high efficiency, environmental protection, and energy conservation. Through the introduction in this article, we hope you have a more detailed understanding of the operation process of electrophoretic painting. When operating, please follow the process to ensure product quality and safety.
