Definitions

  • Spray devices for electrostatic surface coating are known in which the powdery coating material is electrically charged by friction effects when a special duct, which consists of an insulating material that tends to be charged by triboelectric charging, flows through pneumatically, and is drawn into the outlet opening of the duct by flow guide elements (impactors) or radial air jets a highly disperse powder cloud is atomized (DE 1577757, DE 2203351 and DE 2257316).
  • solutions for electrostatic spraying devices are known in which the powder is charged by superimposing triboelectric effects with ionization processes triggered by them (DD 106308, DD 232595).
  • These sprayers contain an earthed electrode, which acts as a passive influencer ionizer, in the entrance zone of the triboelectric charging channel.
  • an earthed electrode acts as a passive influencer ionizer, in the entrance zone of the triboelectric charging channel.
  • the Powder particles dispersed in a carrier gas initially receive a charge due to triboelectric effects when the wall surfaces of the insulating material channel touch. While the charge of the powder particles is continuously transported out of the channel with the flow, an equally large charge of opposite polarity remains on the wall of the insulating material channel. It grows continuously and influences a charge with the same polarity as the powder charge on the grounded electrode until the field that forms between the two charges exceeds the electrical strength of the carrier gas and gas ionization begins in front of the electrode.
