Abstract

PROCEDE PERFECTIONNE POUR LA FABRICATION DE PANNEAUX EN MOUSSE DE POLYSTYRENE PAR FUSION DU POLYSTYRENE A CHAUD DANS UNE EXTRUDEUSE, MELANGE DE LA MASSE FONDUE AVEC UN AGENT MOUSSANT ET EXTRUSION DE GEL FONDU MOUSSABLE AINSI FORME DANS UNE ZONE A PLUS BASSE PRESSION. LE PROCEDE EST CARACTERISE EN CE QUE: 1LE POLYSTYRENE A UN INDICE DE FLUIDITE A L'ETAT FONDU, DETERMINE PAR LA METHODE DE L'ASTM D-1238G, COMPRIS ENTRE 0,5 ET 5; 2L'AGENT MOUSSANT EST CONSTITUE PAR UN MELANGE DE CHLORURE DE METHYLE ET DE CHLORODIFLUOROMETHANE; ET 3LE POLYSTYRENE EST MELANGE DANS L'EXTRUDEUSE AVEC UNE MATIERE AMELIORANT SA FLUIDITE, MATIERE QUI A UN POINT DE FUSION SUPERIEUR A 70C. IL PERMET D'OBTENIR DES PANNEAUX MOUSSES POUR L'ISOLEMENT THERMIQUE QUI ONT UNE EXCELLENTE RESISTANCE MECANIQUE ET UNE BONNE STABILITE DIMENSIONNELLE, MEME A CHAUD, TOUT EN SE PRETANT BIEN A UNE MISE EN FORME PAR EXTRUSION.
