Abstract

PROCEDIMIENTO Y SU APARATO PARA LA FABRICACION DE PRODUCTOS DE MATERIAL PLASTICO DEGRADADO. EL PROCESO COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE REALIZA LA EXTRUSION DE UN MATERIAL PLASTICO DE PARTIDA, SUSTANCIALMENTE LIBRE DE AGENTES DEGRADANTES, A UNA TEMPERATURA RELATIVAMENTE ELEVADA; SEGUNDA, SE INYECTA UNA CANTIDAD RELATIVAMENTE PEQUEÑA DE UNA MEZCLA FORMADA POR MATERIAL PLASTICO DE PARTIDA Y COMO MINIMO UN AGENTE DEGRADANTE, EN EL FLUJO DE MASA FUNDIDA; Y POR ULTIMO, SE DEJA QUE EL MATERIAL PLASTICO DE PARTIDA Y LA MEZCLA INYECTADA, SE MEZCLEN ANTES DE ABANDONAR EL DISPOSITIVO EXTRUSIONADOR. EL APARATO EN EL CUAL SE LLEVA A CABO LA EXTRUSION DEL MATERIAL PLASTICO, CONSTA DE UN EXTRUSIONADOR PRINCIPAL (1) QUE COMPRENDE UN CILINDRO DE EXTRUSION (3) DOTADO DE UNA ABERTURA PARA LA INYECCION, Y UN TORNILLO GIRATORIO (4) SITUADO DENTRO DEL CILINDRO DE EXTRUSION, FORMADO POR UNA ZONA FILETEADA (12), UN CABEZAL DE EXTRUSION (9) Y UN CABEZAL DE MEZCLADO (13); Y DE UN EXTRUSIONADOR AUXILIAR (5).
