1. , for the method for electrostatic coating base material (1), comprise the following steps:

  • The working fluid of 0.5bar to 10bar is provided in the container (2) comprising a large amount of coating powders (3);

    That extracts by working fluid and powder constituent from described container (2) is first-class;

    By the injection of pressure at the working fluid of 0.5bar to 10bar, be atomized described working fluid and powder stream;

    There is provided pressure at the working fluid of 0.5bar to 10bar, to produce the second traffic flow by working fluid and the powder constituent through atomization;

    The second of working fluid described in electrostatic charge and the powder through atomization under stress;

    AndTo base material (1) the described working fluid of upper conveying and the second through electrostatic charge powder through atomization,Described method characteristic is;

    Described working fluid is by the nitrogen within the scope of 80-98%, the oxygen within the scope of 1-90%, the mixture of the argon composition within the scope of 1-2%;

    Continue to obtain described mixture by extracting air and the residuals therefrom removed outside described composition from environment during applying;

    AndBefore entering described container, described workable mixtures is according to the final electrostatic charge cation expected and/or the pre-electric charge of anion electrostatic.
