Résumé

Corona discharge is a method widely used in industrial processes for charging insulating films, non-woven media, or granular materials. Its efficiency is assessed by the high level and the homogeneity of the electric charge distribution at the surface of the exposed bodies. The aim of this work is to evaluate the charging efficiency of a new multi-wire corona electrode. Several geometrical parameters have been taken into consideration, more specifically the number of wires and the distance between any two of them. In the first set of experiments, the I–V characteristic and the distribution of the current density along the ground plane were measured. The second set of experiments were carried out with the objective to record the electric potential at the surface of polypropylene (PP) films exposed to corona discharge generated by these electrodes in two charging modes: static and dynamic. The obtained results point to the distribution of both the corona current density and the electric potential at the surface of PP films.
