ABSTRACT:
An air/liquid polymeric latex foam coating generator includes a static splash plate mixer for forming a coarse foam coating and a conventional static refining mixer which further refines and homogenizes the coarse foam produced by the static splash plate mixer before delivering a refined foam to application heads or nozzles for application to a workpiece. The static splash plate mixer comprises a housing which is divided into two chambers by a splash plate. A stream of pressurized air and a stream of pressurized polymeric latex coating material are introduced into the upstream chamber where the streams intersect each other, impinge upon the splash plate and are mixed into a coarse foam in the upstream chamber. The foam passes through openings in the splash plate to the downstream chamber where the foam is further refine before being discharged from the static splash plate mixer.
