Electrostatic spraying refers to a coating method in which atomized coating is negatively charged under the action of a high-voltage direct-current electric field by utilizing a corona discharge principle and is adsorbed on the surface of a positively charged substrate for discharge. The electrostatic spraying equipment comprises a spray gun, a spray cup, an electrostatic spraying high-voltage power supply and the like. The electrostatic powder spraying technology is a new coating technology which is rapidly developed in recent years, and is characterized in that the energy-saving pollution-free process is simple, the powder can be recycled, the automation is easy to realize, the coating is attractive and beautiful, and the coating is firm and durable, thereby becoming a new development direction of the coating industry. Electrostatic spraying is a spraying method that makes negatively charged paint particles directionally move along the opposite direction of an electric field by using a high-voltage electrostatic electric field and adsorbs the paint particles on the surface of a workpiece. The electrostatic spraying equipment comprises a spray gun, a spray cup, an electrostatic spraying high-voltage power supply and the like. When the electrostatic spraying gun or the spraying disc or the spraying cup works, the coating particle part is connected with the negative electrode, the workpiece is connected with the positive electrode and is grounded, and an electrostatic field is formed between the end part of the spraying gun (or the spraying disc or the spraying cup) and the workpiece under the action of high voltage of a high-voltage power supply. The electric field force on the paint particles is proportional to the voltage of the electrostatic field and the charge of the paint particles, and inversely proportional to the distance between the spray gun and the workpiece, when the voltage is high enough, an air ionization region is formed in the region near the end of the spray gun, the air is ionized and heated violently, a dark red halo is formed around a sharp edge or an electrode needle at the end of the spray gun, and the halo can be seen clearly in the dark, and then the air generates strong corona discharge.
