Abstract

Procédé pour mélanger une matière pigmentaire en poudre ou sous forme granulaire avec une matière plastique de forme similaire pour une extrusion ou un moulage par injection, comprenant la distribution de la matière plastique vers le bas par un étranglement (34) vertical formé par un conduit (28) dans un cylindre (1) d'un appareil d'extrusion ou de moulage par injection la matière pigmentaire étant distribuée vers le bas dans l'écoulement de matière plastique par un ajutage (38) agencé axialement centralement dans l'étrangelement (34), cet ajutage étant placé juste au-dessus d'une paire de vis de mélange (10) appareil pour la mise en oeuvre de ce procédé et leurs utilisations.Process for mixing a powdered or granular pigmentary material with a plastic of similar shape for an extrusion or an injection molding, comprising the distribution of the plastic downwards by a vertical constriction (34) formed by a conduit ( 28) in a cylinder (1) of an extrusion or injection molding apparatus, the pigment material being distributed downward in the plastic flow by a nozzle (38) arranged axially centrally in the constriction (34 ), this nozzle being placed just above a pair of mixing screws (10) apparatus for the implementation of this method and their uses.
