Electrophoresis is a coating method that utilizes electrochemical principles to deposit charged particles as a film on the surface of a conductor under the action of an electric field. It involves suspending charged particles in water or an organic solvent and causing them to precipitate on the surface of a metallic or non-metallic conductor by electric field attraction, thus forming a covering coating. The electrophoresis process is categorized into anodic electrophoresis and cathodic electrophoresis, depending on the charged nature of the paint particles and the electrode properties of the workpiece. For example, if the paint particles are negatively charged and the workpiece is the anode, the paint particles will be deposited into a film on the workpiece under the action of electric field force, which is called anodic electrophoresis; conversely, if the paint particles are positively charged and the workpiece is the cathode, the paint particles will be deposited into a film on the workpiece, which is called cathodic electrophoresis.
The electrophoresis process is used in a wide range of applications including, but not limited to, metal surface treatment, of which automotive electrophoretic painting is an important application. In this process, an automobile part is immersed in a solution containing charged paint particles, and then by the action of an applied electric field, the charged paint particles move directionally under the force of the electric field and are deposited on the surface of the automobile part to form a homogeneous and strongly adherent coating.
In addition, electrophoresis is not limited to industrial applications, but also plays an important role in scientific fields such as DNA analysis and remediation of contaminated soil. In scientific research, electrophoresis is used to separate and analyze charged particles, using the different speeds of different charged particles in the electric field to achieve the purpose of separation.
