Description
technical field [0001] The present disclosure relates to an electrostatic coating device that sprays paint applied with a high voltage toward an object to be coated in a mist form. Background technique [0002] When coating the object to be coated such as the body of an automobile, an electrostatic coating device is used to improve the coating efficiency of the paint. This electrostatic painting device paints by applying a high voltage to the paint. In addition, in the recent coating equipment, the use of solvents such as thinners is restricted in consideration of the environment, and water-based paints are used. However, in the case of using water-based paint, the applied high voltage leaks through the water-based paint in the paint supply flow path continuing from the painting device to the paint supply source. Therefore, a coating device using a water-based paint cannot directly apply a high voltage to the paint and apply the paint. [0003] Then, among the electrostat...
