Method and fluidized strength sodium container for improvement of the charge of powder particles by means of new pulsed high voltage technology

摘要

A method for electrostatic coating of an object by means of an electrostatic with powder fluidisation container, wherein in the fluidized strength sodium vessel, the powder to be coated is fluidized and as a powder cloud is electrostatically charged and the object is introduced into the powder cloud, characterized in that the powder in the fluidized strength sodium container by means of a pulsed voltage is electrostatically charged, wherein the pulsed voltage with a frequency less than 20 hz is in a pulsed fashion.
