Abstract

PROCEDE D'EXTRUSION DE POLYMERES A HAUTS POURCENTAGES D'AGREGATS, OU L'ON ENTEND PAR UN TEL TERME DES POURCENTAGES DE 35-40% DU POIDS A 70-80%DU POIDS DE LA TOTALITE, COMPRENANT LES ETAPES DE : ALIMENTATION DE QUANTITES EXACTEMENT DOSEES DES COMPOSANTS ET DES ADDITIFS DANS DES ENDROITS AXIALEMENT ELOIGNES D'UN MELANGEUR A VIS SANS FIN ; MELANGE INTIME DE CES COMPOSANTS ; ET EXTRUSION DE CEUX-CI A TRAVERS LA TETE D'EXTRUSION DE CE MELANGEUR. CE PROCEDE EST REALISE AU MOYEN D'UN DISPOSITIF COMPRENANT UNE PRESSE D'EXTRUSION (1) DE TRANSFORMATION D'UN MELANGE COMPOSE D'AU MOINS UN POLYMERE, UN AGREGAT ET UN OU PLUSIEURS ADDITIFS TELS QUE DES LUBRIFIANTS, STABILISANTS OU AUTRES, DES MOYENS (2,3,4) DE STOCKAGE DE CHACUN DES COMPOSANTS DU MELANGE, DES DISPOSITIFS (21,31,41) DE PESAGE EN CONTINU DE CHACUN DE CES COMPOSANTS ET DES MOYENS (6,8,9) D'ALIMENTATION DE CES COMPOSANTS. CES MOYENS (6,8,9)D'ALIMENTATION SONT PLACES EN DES ENDROITS PREETABLIS LE LONG DE LA PRESSE D'EXTRUSION (1) EN FONCTION DE LA COMPOSITION DU MELANGE A TRANSFORMER.PROCESS FOR THE EXTRUSION OF POLYMERS WITH HIGH PERCENTAGES OF AGGREGATES, WHEREIN IS DEFINED PERCENTAGES OF 35-40% BY WEIGHT TO 70-80% OF THE WEIGHT OF THE TOTALITY, INCLUDING THE STEPS OF: FEEDING QUANTITIES EXACTLY DOSE OF COMPONENTS AND ADDITIVES IN AXIALLY AWAY PLACES FROM AN ENDLESS SCREW MIXER; INTIMATE MIXTURE OF THESE COMPONENTS; AND EXTRUSION THEREOF THROUGH THE EXTRUSION HEAD OF THIS MIXER. THIS PROCESS IS CARRIED OUT BY MEANS OF A DEVICE INCLUDING AN EXTRUSION PRESS (1) FOR TRANSFORMING A MIXTURE COMPOSED OF AT LEAST ONE POLYMER, AN AGGREGATE AND ONE OR MORE ADDITIVES SUCH AS LUBRICANTS, STABILIZERS OR THE LIKE MEANS (2,3,4) FOR STORING EACH OF THE MIXTURE COMPONENTS, DEVICES (21,31,41) FOR CONTINUOUSLY WEIGHING EACH OF THESE COMPONENTS AND MEANS (6,8,9) FOR FEEDING THESE COMPONENTS. THESE MEANS (6, 8, 9) OF SUPPLY ARE PLACED IN PRE-ESTABLISHED LOCATIONS ALONG THE EXTRUSION PRESS (1) ACCORDING TO THE COMPOSITION OF THE MIXTURE TO BE PROCESSED.
