Abstract
An electrostatic painting system for painting an object or article under corona discharge. The system comprises a spray gun which is formed at its tip end with annular air ejection opening through which air is ejected under pressure to atomize liquid paint ejected from a paint ejection opening formed at the tip end of the spray gun. An annular wire netting-like negative electrode is fixedly disposed at the tip end of the spray gun and located coaxially around the air ejection opening. The electrode functions to form an electrostatic field and a corona discharge field between the electrode and the object to be painted and to provide electric charge to the atomized paint, upon a high negative voltage being applied to the electrode.
