Abstract

LA INVENCION CONSISTE EN UN PROCEDIMIENTO PARA LA ELABORACION DE ESPUMA DE PAPEL DE PAPEL VIEJO Y/O CARTON, POR EL CUAL ESTE MATERIAL DE PARTIDA EN PRIMER LUGAR SE CONVIERTE EN UNA MASA DE FIBRAS Y DESPUES SE MEZCLA CON UN PRODUCTO CAUSTICO, POR EL CUAL LA MEZCLA ENTONCES, MEDIANTE APLICACION DE ENERGIA TERMICA Y MECANICA EN UN EXTRUSIONADOR, ES COMPRIMIDA Y PLASTIFICADA. A LA SALIDA DEL EXTRUSIONADOR SE EXPANDE POR MEDIO DE LA DISMINUCION DE LA TEMPERATURA Y DE LA PRESION. PARA LA ACELERACION DEL PROCESO EN EL EXTRUSIONADOR SE PROPONE CONFORME A LA INVENCION, QUE EN LA FASE DE LA ELABORACION DE LA MASA DE FIBRAS SE AGREGUE ALCOHOL POLIVINILICO (PVA).
