Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic spraying auxiliary spray guns, in particular to an electrostatic spraying auxiliary spray gun. Background Art

[0002] Electrostatic spraying of steel pipes refers to a spraying method that uses a high-voltage electrostatic field to make negatively charged paint particles move in a directional direction opposite to the electric field, and adsorb the paint particles on the surface of the steel pipe. Its working principle is: a high-voltage corona discharge electric field is formed between the spray gun and the steel pipe. When the powder particles are ejected from the spray gun nozzle and pass through the discharge area, they collect a large number of electrons and become negatively charged particles. Under the action of electrostatic attraction, they are adsorbed onto the positively charged steel pipe. However, the current electrostatic spray auxiliary spray gun does not have a filtering function, which makes it easy to get clogged during long-term use, and it is not convenient for people to spray at high places, resulting in inconvenience in use. For this reason, we propose an electrostatic spray auxiliary spray gun. Utility Model Content
