Surface treatment by spraying an active liquid agent

摘要

A process is claimed for the surface treatment of components by spraying an active liquid agent onto the surfaces of these components (9) in an installation (1) mainly comprising a treatment enclosure (20; a device (7) for supporting the components (9) above the bottom (5) of this enclosure (2); some means for spraying the active liquid agent onto the components (9); and some means for the recovery and filtration of the active agent from the bottom (5) of the enclosure (2). The active liquid agent is sprayed onto the components (9) during a plurality of periods of spraying the active agent alternating with a plurality of periods of not spraying the active agent. The components (9) in the enclosure (2) are moved during at least one of these periods of spraying. The installation used for this process is also claimed.
