Abstract
LA INVENCIÓN SE RELACIONA CON UN MÉTODO DE DESAGÜE DE SEDIMENTO PROVENIENTE DE UN PROCESO DE FABRICACIÓN DE PULPA, PAPEL O CARTÓN, COMO SEDIMENTO DE DESTINTADO. EL MÉTODO COMPRENDE LA OBTENCIÓN DE UN SEDIMENTO ACUOSO QUE COMPRENDE UNA FASE ACUOSA Y MATERIAL DE FIBRAS SUSPENDIDO EN LA FASE ACUOSA. EL SEDIMENTO SE SOMETE A UN PASO DE ESPESADO PREVIO, DONDE SE EXTRAE UNA PRIMERA PARTE DE LA FASE ACUOSA DEL SEDIMENTO, Y A UN PASO DE PRENSADO, DONDE SE EXTRAE UNA SEGUNDA PARTE DE LA FASE ACUOSA DEL SEDIMENTO. DE ESTE MOMENTO, SE OBTIENE SEDIMENTO PRENSADO SECO. ANTES DEL PASO DE ESPESADO PREVIO, O DURANTE ESTE, SE AGREGA AL SEDIMENTO UNA COMPOSICIÓN POLIMÉRICA CON UNA DENSIDAD DE CARGA MÁXIMA DE 1,7 MEQ/G, DE PREFERENCIA UNA MÁXIMA DE 1,5 MEQ/G, DE MAYOR PREFERENCIA UNA MÁXIMA DE 1,1 MEQ/G. LA COMPOSICIÓN POLIMÉRICA COMPRENDE UN PRIMER POLÍMERO CATIÓNICO SINTÉTICO, CON UNA DENSIDAD DE CARGA DE AL MENOS 1,0 MEQ/G A UN PH DE 2,8, Y UN SEGUNDO POLÍMERO CATIÓNICO, QUE CORRESPONDE A UN COPOLÍMERO OBTENIDO MEDIANTE POLIMERIZACIÓN DE (MET)ACRILAMIDA Y AL MENOS UN SEGUNDO MONÓMERO CATIÓNICO, YENDO LA CANTIDAD DE LOS MONÓMEROS CATIÓNICOS DE 2 A 19 % POR PESO CALCULADA A PARTIR DE LA CANTIDAD TOTAL DE MONÓMEROS, SEGUNDO POLÍMERO QUE SE POLIMERIZA EN PRESENCIA DEL PRIMER POLÍMERO CATIÓNICO. EL PRIMER POLÍMERO TIENE MAYOR DENSIDAD DE CARGA QUE EL SEGUNDO POLÍMERO.
