Abstract

LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA RECICLAR COPOS DE TEREFTALATO DE POLIETILENO (PET), CARACTERIZADO PORQUE LOS COPOS SE EXTRUYEN Y GRANULAN EN VACIO, DESPUES DE LO CUAL SE POS - CONDENSA EN GRANULADO EN FASE SOLIDA Y EN VACIO. LA EXTRUSION SE DESARROLLA PREFERENTEMENTE EN ZONAS DIFERENCIADAS DE VENTILACION, Y LA POS - CONDENSACION DE LA FASE SOLIDA DEPENDE DE LA TEMPERATURA, EL VACIO Y EL TIEMPO EMPLEADO EN UNA SECADORA DE TAMBOR. ESTA SECADORA ASEGURA LA MEZCLA UNIFORME Y CUIDADOSA Y UNA VISCOSIDAD CONSTANTE DEL PRODUCTO PET. ESTE PROCEDIMIENTO SE UTILIZA EN PARTICULAR PARA FABRICAR BOTELLAS DE PET PARA BEBIDAS.
