Abstract

METODO PARA LA PRODUCCION DE MEMBRANA DE FIBRA HUECA, MEDIANTE LOS PASOS DE LA DESCARGA DE UN BARNIZ EN ESPIRAL A TRAVES DE UNA BOQUILLA ESPIRAL ANULAR Y, AL MISMO TIEMPO, LA INTRODUCCION DE UN LIQUIDO ANTICOAGUALNTE PARA EL BARNIZ EN LA CAVIDAD CENTRAL DE UNA FIBRA HUECA DEL BARNIZ QUE SE ESTA DESCARGANDO, Y LA POSTERIOR INTRODUCCION DE LA FIBRA DE DESCARGA DEL BARNIZ EN UN LIQUIDO COAGULANTE DONDE SE SOLIDIFICA LA FIBRA DESCARGADA EN UNA MEMBRANA DE FIBRA HUECA. ESTE METODO SE CARACTERIZA POR LA INCORPORACION DE UN AGENTE MODIFICADOR DE LA SUPERFICIE EN DICHO LIQUIDO ANTICOAGULANTE, MODIFICANDO EL COMPORTAMIENTO DE LA SUPERFICIE INTERNA DE LA MEMBRANA DE FIBRA HUECA PRODUCIDA.
