Abstract

UNA MEZCLA LIQUIDA DE DOS FASES COMPUESTA DE UNA COLADA DE PLASTICO TERMOPLASTICA Y UNA FASE DE AGUA, EN PARTICULAR UN COAGULADO LATEX, SE ELIMINA DE AGUA EN UN EXTRUSIONADOR (1) DE DOBLE TORNILLO SINFIN GIRANDO EN CONTRASENTIDO BAJO UNA PRESION, QUE ES MAYOR QUE LA PRESION DE VAPOR DEL AGUA CORRESPONDIENTE A LA TEMPERATURA DE LA COLADA DEL MATERIAL (7) SINTETICO TERMOPLASTICO DE UNA MANERA, QUE LA COLADA EN LA ZONA DE ELIMINACION DE AGUA SE TRANSPORTA EN LA VIA DE LOS TORNILLOS SINFIN PARCIALMENTE RELLENOS. EN AL MENOS UNA DE ESTAS VIAS DE TORNILLO SINFIN, EN EL ESPACIO DE ADMISION DEL TORNILLO (1) SINFIN DOBLE SE MANTIENE EN SITUACION DE REMANSO BAJO FORMACION DE UN GRADIENTE DE PRESION EMPINADO, LIMITADO DE FORMA ESTRECHA LOCALMENTE CON RESPECTO A UNA TORTA (7) DE COLADA SUSPENDIDA DE FORMA CONJUNTA Y DE MODO QUE EL AGUA ANTES DEL LIMITE DE LA TORTA DE COLADA SE DEJA EVACUAR BAJO EL EFECTO DE LA FUERZA DE GRAVEDAD EN FORMA LIQUIDA HACIA ABAJO A TRAVES AL MENOS DE UNA ABERTURA (8) DE EVACUACION, DE TAL MODO QUE LA TORTA (7) DE COLADA NO SE ENCUENTRA EN CONTACTO CON UNA FASE DE AGUA DE SUSPENSION CONJUNTA.
