Abstract

L'INVENTION CONCERNE UN PROCEDE DE MELANGE D'UNE COMPOSITION CONDUCTRICE DE MOULAGE A BASE DE CHLORURE DE POLYVINYLE CONTENANT DES QUANTITES SUFFISANTES DE PARTICULES CONDUCTRICES DE NOIR DE FUMEE POUR QUE LA COMPOSITION RESULTANTE AIT UNE RESISTIVITE INFERIEURE A ENVIRON 500OHM-CM A 900MHZ. SELON L'INVENTION, ON SUBDIVISE LES PARTICULES DE NOIR DE FUMEE A UNE DIMENSION DE 0,044MILLIMETRES OU MOINS ET ON AJOUTE CES PARTICULES, PAR PORTIONS, A LA RESINE DE CHLORURE DE POLYVINYLE AFIN D'OBTENIR UNE DISPERSION UNIFORME. ON EMPLOIE UNE TREMIE 11 DE NOIR DE FUMEE, UNE UNITE 12 DE PESAGE DE NOIR DE FUMEE, UN BROYEUR 16, UN COLLECTEUR 24 DE POUSSIERE DE NOIR DE FUMEE, UN SEPARATEUR A CYCLONE 18, UNE TREMIE 20 COLLECTRICE DE NOIR DE FUMEE, UNE TREMIE 28 DE PESAGE DE RESINE DE VINYLE, UNE TREMIE 30 DE PESAGE D'ADDITIFS SOLIDES, UNE ALIMENTATION 33 EN ADDITIFS LIQUIDES, UN MELANGEUR 22 DE FORTE INTENSITE ET UN REFROIDISSEUR 34. L'INVENTION S'APPLIQUE NOTAMMENT AUX COMPOSITIONS DE MOULAGE POUR VIDEODISQUES.
