Abstract

SISTEMA Y METODO PARA MEDIR EL POTENCIAL ZETA DE SUSPENSIONES DE PARTICULAS. LA INVENCION SE REFIERE A UN SISTEMA PARA MEDIR EL POTENCIAL ZETA DE SUSPENSIONES DE PARTICULAS ASI COMO UN METODO PARA MEDIR EL POTENCIAL ZETA DE DICHAS SUSPENSIONES. LA INVENCION COMPRENDE UN MEDIO POROSO (2), UNA PIEZA ESTANCA MOVIL (3) UNIDA A UN MECANISMO DE GIRO (4) CONECTADO A UN DISPOSITIVO REGULADOR (5). EN LA TUBERIA (1) SE INTRODUCEN DOS ELECTRODOS (6) CONECTADOS A UN MEDIO DE AMPLIFICACION (7) Y TRATAMIENTO DE LA SEÑAL (8), Y UN DISPOSITIVO PARA MEDIR LA PERDIDA DE CARGA (9). DE ESTA FORMA CUANDO LA SUSPENSION DE PARTICULAS CIRCULA A TRAVES DE LA CONDUCCION SE FORMA UNA TORTA DE FIBRAS SOBRE EL MEDIO POROSO Y SE DETERMINA EL POTENCIAL DE CORRIENTE Y LA PERDIDA DE CARGA GENERADOS. UNA VEZ REALIZADA LA MEDIDA, SE HACE GIRAR EL MEDIO POROSO PARA QUE LA PROPIA DISOLUCION CLARIFICADA ARRASTRE LA TORTA FORMADA, A LA VEZ QUE SE REALIZA UNA NUEVA MEDIDA. ESTE SISTEMA ES ESPECIALMENTE UTIL PARA EL ESTUDIO DE SUSPENSIONES DE PAPEL, ENTRE OTRAS.
