Elektrostatisches Beschichtungsverfahren und elektrostatische Beschichtungsvorrichtung

DE 102009020415 A1 UPAB: 20101130 NOVELTY - The electrostatic coating method involves producing an electrical field within a drift range by generation of a voltage. The voltage is periodically changed and the material is brought only at times into the drift range, to which the voltage is either more largely, or equal to a positive threshold value or smaller or equal to a negative threshold value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electrostatic coating method. USE - Electrostatic coating method for coating of a surface with a material. ADVANTAGE - The voltage is periodically changed and the material is brought only at times into the drift range, to which the voltage is either more largely, or equal to a positive threshold value or smaller or equal to a negative threshold value, and hence ensures that quality and adhesion of the coating layer at the surface is improvable
