Abstract

PROCEDIMIENTO PARA HILAR DISOLUCIONES DE CARBAMATO DE CELULOSA POR EXTRUSION DE LA DISOLUCION A TRAVES DE UNA TOBERA DE HILADO EN UN BAÑO DE PRECIPITACION, COAGULACION DE LAS FIBRAS FORMADAS DE CARBAMATO DE CELULOSA Y EXTRACCION DE LAS FIBRAS POR MEDIOS MECANICOS, ENVOLVIENDOSE LAS FIBRAS DESDE LA SALIDA DE LA TOBERA DE HILADO HASTA LA SALIDA DEL BAÑO DE PRECIPITACION DE UNA CORRIENTE UNIFORME DEL ELEMENTO PRECIPITADOR, CUYA VELOCIDAD DE FLUJO EN LA SALIDA DE LAS FIBRAS DE LA TOBERA DE HILADO (PLANO X1) ES ENTRE 0,1 Y 0,8 VECES LA VELOCIDAD DE EXTRACCION DE LAS FIBRAS Y EN LA SALIDA DE LAS FIBRAS DEL BAÑO DE PRECIPITACION (PLANO X3) ES ENTRE 0,96 Y 1,1 VECES. DISPOSITIVO PARA LA REALIZACION DE ESTE PROCESO COMPUESTO BASICAMENTE DE UN CONTENEDOR DEL BAÑO DE PRECIPITACION (15) Y DE UNA TOBERA DE HILADO (3) CON FORMA TRONCOCONICA CONSTRUIDA COMO CUERPO DE FLUJO EN EL INTERIOR DEL CONTENEDOR Y DE UN EMBUDO DE HILADO (5) CON FORMA TRONCOCONICA, CON UN TUBO (6) CILINDRICO CONECTADO, QUE ATRAVIESALAS PAREDES DEL CONTENEDOR DEL BAÑO DE PRECIPITACION, SUMERGIENDOSE LA TOBERA DE HILADO (3) EN EL EMBUDO DE HILADO FORMANDO UNA RANURA CONCENTRICA Y PRESENTANDO PREFERIBLEMENTE EL MISMO ANGULO DEL CONO (A), QUE DISMINUYE EN LA DIRECCION DEL FLUJO, QUE EL EMBUDO DE HILADO.
