Abstract
SE DESCRIBE UN PROCEDIMIENTO MEJORADO PARA EL DESTINTADO DE PAPEL VIEJO QUE CONTIENEN TONER/TINTAS DE IMPRESION CON LASER, ELECTROSTATICA Y OTROS SISTEMAS DE IMPRESION NO IMPACTANTES PARA PRODUCIR UNA PULPA DE ALTA DENSIDAD (MUCHO BRILLO, POCO O NADA DE POLVO) CON POCA O NINGUNA PERDIDA DE FIBRA. EL PROCEDIMIENTO IMPLICA LA UNION DE LAS PARTICULAS DE TINTA DE LA PULPA DEL PAPEL VIEJO A UN MATERIAL VEHICULO MAGNETICO CON LA AYUDA DE UN AGENTE DE AGLOMERACION SEGUIDO DE LA ELIMINACION DE LAS PARTICULAS DE TINTA UNIDAS POR SEPARACION MAGNETICA. EL TRATAMIENTO MAGNETICO SE REALIZA PREFERENTEMENTE A TEMPERATURA AMBIENTE O SUPERIOR, A UN PH NEUTRO A ALCALINO Y CON POCA CONSISTENCIA DE LA PULPA. LA AGLOMERACION Y LA ADICION MAGNETICA, SEGUIDO DE LA EXPOSICION DEL PAPEL VIEJO REPULPADO A UN CAMPO MAGNETICO PROPORCIONA UNA ELIMINACION CASI COMPLETA DE LA TINTA DURANTE LA EXPOSICION AL CAMPO MAGNETICO SIN DICHO PRETRATAMIENTO. ASI, EL PROCEDIMIENTO SE PUEDE EMPLEAR COMO UNA ETAPA ADICIONAL EN UN PROCEDIMIENTO CONVENCIONAL PARA LA ELIMINACION DE TINTAS DE PAPELES IMPRESOS DE REPROGRAFIA, TAL COMO LA ELIMINACION DE TINTA POR CRIBADO, FLOTACION, LIMPIEZA CENTRIFUGA, LAVADO Y SEDIMENTACION CON O SIN DECANTACION.
