[0002] Electrostatic spraying is a coating method that uses an electrostatic field to adsorb charged paint particles onto the surface of a workpiece. Its principle is based on the Coulomb force between charges. Paint particles are charged through corona discharge or triboelectric charging. Under the influence of the electrostatic field, these charged particles move directionally and adhere to the workpiece surface, forming a uniform and continuous coating that provides both decoration and protection. It boasts advantages such as high coating efficiency, good coating quality, energy saving, and environmental friendliness. It is widely used in the automotive, furniture, machinery manufacturing, shipbuilding, railway vehicle, and petrochemical industries, and can be applied to the coating of automobile bodies and parts, the decoration and protection of furniture surfaces, and the corrosion prevention and decoration of metal surfaces such as machinery, pipelines, and storage tanks.
