Application of high voltage electrostatic transformer module in electrostatic spray gun

Today let’s talk about the application of high voltage electrostatic modules in powder coating spay guns.

Static electricity is everywhere in our lives. For example, in the dry winter, when people take off sweaters, wool, and nylon clothes, they often hear crackling sounds and flashing sparks. When I wake up in the morning and brush my hair, my hair will often "float" and become more messy. When fingers touch metal objects such as doorknobs, faucets, chair backs, etc., there will be electric shocks. These are common static phenomena. Static electricity is formed by friction or by redistribution of charges due to mutual attraction. Static electricity is formed when charges accumulate on an object or surface.

Electrostatic spraying has a wide range of applications, from large railroads, vehicles, and tractors, to small workpieces, toys, and household appliances.

The high voltage electrostatic transformer power supply mainly adopts the corona discharge electrostatic powder spray gun system to complete the powder spraying. The system includes: 1) High voltage electrostatic generator (composed of high frequency transformer and booster circuit): 2) Corona discharge electrode (composed of needle electrode and ring electrode): 3) Jet regulator: 4) Air And powder conveying pipeline, etc. With the continuous development and innovation of spraying technology, it is now possible to install high-voltage modules for electrostatic spray gun powder coatings inside electrostatic powder spray guns. Turn on the low-voltage power supply, convert it into high-voltage electricity through a multi-stage booster, and apply it to the corona discharge electrode or ring electrode at the end of the spray gun to ionize the air around the electrode and connect it with the grounded workpiece (usually the anode. positively charged) to form an electric field. The powder coating is delivered to the front end of the spray gun by compressed air. When atomized and sprayed, the powder will be negatively charged when it passes through the electric field, and will fly to the surface of the workpiece under the action of the electric field force (electrostatic attraction) and compressed air, and will be adsorbed on the workpiece.

The high voltage cascade is characterized by stable performance and good quality. It can be used to manual or automatic powder coating gun. Electrostatic powder coating gun high voltage generator cascade is sealed with high-quality resin, with mature technology, good insulation, not easy to break down, and high electrostatic output.
