Abstract

L'invention concerne un procédé de séparation de l'excédent de peinture pulvérisée (overspray) à partir de l'air chargé de peinture dans les cabines d'installations de revêtement, en particulier des installations de peinturage. L'excédent de peinture est entraîné par un flux d'air et conduit vers un dispositif de séparation fonctionnant de manière électrostatique (42 ; 1042 ; 2042). Dans celui-ci, une grande partie d'au moins les solides composant l'excédent de peinture est déposée sur au moins une surface de séparation (46, 48 ; 1046, 1048 ; 2046, 2048 ; 3046, 3048 ; 5046, 5048). On utilise comme moyen de séparation un matériau électriquement conducteur ou un mélange de matériaux électriquement conducteurs, qui est appliqué sur ladite au moins une surface de séparation (46, 48 ; 1046, 1048 ; 2046, 2048 ; 3046, 3048 ; 5046, 5048) du dispositif de séparation (42 ; 1042 ; 2042) et qui, à la température de travail du dispositif de séparation (42 ; 1042 ; 2042), présente une consistance cireuse. L'invention concerne en outre un dispositif de séparation (42 ; 1042 ; 2042) avec un tel matériau cireux et une installation de revêtement d'objets.
