METHOD FOR THE ELECTROSTATIC APPLICATION OF A POWDER ON A SUPPORT WITH A SURFACE CONDITION IN PARTICULAR IRREGULAR

摘要

P The invention relates to a method of covering a support (1) comprising a surface to be coated (2) comprising in particular a zone (5) having an irregular surface state, in which a (6) is emitted a jet with an electrically charged powder in the direction of the support, an electrical potential is established (16) at the surface to be coated so that the powder is attracted to this surface. To improve powder deposition, in particular carried out at the level of the irregular zone, a deflector (17) is used so as to modify the stroke of a part of the emitted particles, so that these deflected particles form a cloud (18) between the deflector and the irregular area, to ensure a uniform deposit regardless of the direction (7) of the powder jet, while maintaining the visibility of surface irregularities. /P
