Abstract

PROCEDIMIENTO PARA REFUNDIR POLIMEROS DE POLIAMIDA.COMPRENDE AN/ADIR UNA CANTIDAD CONTROLADA DE AGUA AL POLIMERO PREVIAMENTE SOMETIDO A UNA FASE DE SECADO Y QUE NO ALCANCE EL RE-EQUILIBRIO CON HUMEDAD Y CUANDO ESTA EN ESTADO FUNDIDO O INMEDIATAMENTE ANTES DE SU REFUSION LA CUAL TIENE LUGAR EN UN EXTRUDER DE TORNILLO. EL AGUA SE AN/ADE EN UN PUNTO A LO LARGO DEL CILINDRO DEL EXTRUDER ANTES DEL PUNTO EN DONDE COMIENZA LA FUSION DEL POLIMERO. AL MISMO TIEMPO SE DISPONE DE UN ELEMENTO PARA DETECTAR CUALQUIER DESVIACION DE LA VISCOSIDAD DEL POLIMERO FUNDIDO EXTRUIDO CON RESPECTO A UN VALOR ESTABLECIDO Y PARA AJUSTAR LA CANTIDAD DE AGUA AN/ADIDA AL POLIMERO PARA CORREGIR TAL DESVIACION.
