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).THE INVENTION CONSISTS OF A PROCEDURE FOR THE ELABORATION OF FOAM OF OLD PAPER PAPER AND / OR CARDBOARD, BY WHICH THIS STARTING MATERIAL FIRSTLY BECOMES A MASS OF FIBERS AND THEN IT IS MIXED WITH A CAUSTIC PRODUCT, FOR WHICH THE MIXTURE THEN, THROUGH APPLICATION OF THERMAL AND MECHANICAL ENERGY IN AN EXTRUSIONER, IS COMPRESSED AND PLASTIFIED. AT THE EXIT OF THE EXTRUSIONER IT EXPANDS THROUGH A DECREASE IN TEMPERATURE AND PRESSURE. FOR THE ACCELERATION OF THE PROCESS IN THE EXTRUSIONER IT IS PROPOSED ACCORDING TO THE INVENTION, THAT IN THE PHASE OF ELABORATION OF THE MASS OF FIBERS ADD POLYVINYL ALCOHOL (PVA).
