Abstract

PRODUCTO DE EXTRUSION TALES COMO CABLES, TUBOS, PELICULAS SOPLADAS, ETC., CONSISTENTES EN VARIAS CAPAS DE MATERIALES, SE FABRICAN GENERALMENTE UTILIZANDO BOQUILLAS DE CAPAS MULTIPLES EN LAS QUE LAS MASAS SON DIVIDIDAS EN DIFERENTES COMPONENTES DE FLUJO, QUE LUEGO SON COMBINADOS DE NUEVO PARA PRODUCIR UNA ESTRUCTURA TUBULAR. EN EL METODO DE EXTRUSION DEL INVENTO, LAS MASAS CIRCULANTES SON HOMOGENEIZADAS POR MEDIO DE ROTORES QUE GIRAN ENTRE PLACAS SITUADAS UNAS ENCIMA DE OTRAS, SIENDO INTRODUCIDAS LAS MASAS DE MATERIAL PLASTICO EN LOS ESPACIOS DE ROTORES ENTRE LAS PERIFERIAS DE LOS ROTORES Y SIENDO HECHAS PASAR A LOS BORDES INTERNOS CIRCULARES DE LOS ROTORES, DESDE DONDE AVANZAN EN UN FLUJO TUBULAR DENTRO DE LAS BOQUILLAS.
