Abstract

Appareil de pulvérisation électrostatique pour déposer une matière de revêtement sur une scène. Cet appareil comprend des moyens pour assurer la dispersion d'un courant de matière de revêtement sous la forme d'un jet de particules, des électrodes placées dans une position adjacente aux moyens de dispersion pour définir une région dans laquelle une charge électrostatique est conférée aux particules pulvérisées, des moyens pour relier un dispositif d'application de potentiel auxdites électrodes afin d'appliquer un potentiel électrique à ladite zone de charge électrostatique des particules, et des moyens pour diriger un écoulement de gaz afin de le faire entrer en contact avec lesdites électrodes pour maintenir ces électrodes sensiblement exemptes de particules déposées. Utilisation de peinture à base aqueuse dans des dispositifs de pulvérisation électrostatique.An electrostatic spray apparatus for depositing a coating material on a stage. This apparatus comprises means for dispersing a stream of coating material in the form of a jet of particles, electrodes placed in a position adjacent to the dispersing means for defining a region in which an electrostatic charge is imparted to the particles. atomized particles, means for connecting a potential applying device to said electrodes in order to apply an electric potential to said electrostatic charge zone of the particles, and means for directing a flow of gas to contact it with said particles. electrodes to keep these electrodes substantially free of deposited particles. Use of water-based paint in electrostatic spray devices.
