Abstract :
In electrostatic powder coating, using a frictional charger, a serious problem is the poor charging characteristics of powder paint. In order to overcome this problem, the authors have investigated a new system composed of a plasma generator and a frictional charger. The results obtained for two kinds of polyester powder paints showed that the plasma has a strong effect on the characteristics of frictional charging in powder paint; the frictional charge was more than five times as large as that without plasma effects
