Abstract

SE PRESENTA UNA CABEZA DE EXTRUSION DE RESINA DE POLIMERO QUE INCLUYE UNO O MAS MODULOS ANULARES DE EXTRUSION EN LA CUAL UN CANAL ESPIRAL QUE TIENE UNA O MAS VUELTAS SE EXTIENDE DESDE LA ENTRADA DE LA RESINA SOBRE LA PERIFERIA DEL MODULO HASTA UNA SALIDA DE EXTRUSION. PREFERIBLEMENTE, EL CANAL SE ABRE GRADUALMENTE AL INTERIOR DE UN ESPACIO FRUSTOCONICO ANULAR QUE SE DIRIGE HACIA LA SALIDA DE EXTRUSION EN EL BORDE INTERIOR DEL MODULO. EL CANAL ESPIRAL SE EXTIENDE SIMETRICAMENTE ALREDEDOR DEL MODULO O MODULOS DE EXTRUSION DE FORMA QUE EXPONGA A TODO EL POLIMERO EXTRUDIDO QUE FLUYE DESDE LA ENTRADA HASTA LA SALIDA DE EXTRUSION A SUSTANCIALMENTE LAS MISMAS CONDICIONES DE PROCESO A LO LARGO DEL CAMINO DE FLUJO. COMO RESULTADO, EL POLIMERO SE DISTRIBUYE EN LA SALIDA CON PROPIEDADES QUE SON SUBSTANCIALMENTE SIMETRICAS ALREDEDOR DEL EJE DEL MODULO O MODULOS DE EXTRUSION PARA LA RESINA DISTRIBUIDA HACIA LA SALIDA. ES PREFERIBLE QUE EL MODULO O MODULO DE EXTRUSION COMPRENDAN UN PAR DE MIEMBROS ANULARES CONFRONTABLES CON PARTES CENTRALES FRUSTOCONICAS QUE TENGAN CUSPIDES CON UNA DIMENSION AXIAL MAYOR QUE LA DIMENSION AXIAL DE LAS PARTES EXTERIORES DE LOS MODULOS DE MANERA QUE SE FORMEN ESPACIOS DE AIRE ALREDEDOR DE CADA MODULO INCLUYENDO UN ESPACIO DE AIRE FRUSTOCONICO PARA EVITAR LA TRANSFERENCIA DE CALOR DIRECTA ENTRE LOS MODULOS ADYACENTES.
