Abstract

SE PROPORCIONA UNA CABEZA DE EXTRUSION DE RESINA DE POLIMERO PARA MOLDEAR ARTICULOS TUBULARES MULTICAPA CON RESINAS DE VISCOSIDADES NO IGUALES EN DONDE TALES RESINAS NO SE COMBINAN EN UNA ESTRUCTURA MULTICAPA HASTA UN PUNTO CERCA DE LA SALIDA DE LA CABEZA DE EXTRUSION PARA MINIMIZAR LOS FLUIDOS INESTABLES. EN ALGUNAS PUESTAS EN PRACTICA, LA CAPA INTERIOR DE LA ESTRUCTURA MULTICAPA SE AÑADE LA ULTIMA PARA AYUDAR A MINIMIZAR LOS FLUJOS INESTABLES. EN PUESTAS EN PRACTICA PREFERENTES, LOS FLUJOS INESTABLES SE MINIMIZAN MEDIANTE LA COMBINACION DE TODOS LOS COMPONENTES DE LA ESTRUCTURA MULTICAPA DENTRO DE 4'''' DE LA SALIDA DE LA CABEZA DE EXTRUSION.
