Abstract

PROCEDIMIENTO DE OBTENCION POR AGLOMERACION DE AGENTES FILTRANTES DIATOMITICOS SIN CRISTOBALITA Y CON PERMEABILIDAD CONTROLADA, QUE COMPRENDE UNA ETAPA DE AMASADO DE UNA DIATOMITA CON UN LIGANTE CONSTITUIDO POR UNA SOLUCION ACUOSA DE UN SILICATO ALCALINO O DE ACIDO SILICICO, Y UNA ETAPA ULTERIOR DE CALCINACION A UNA TEMPERATURA QUE NO EXCEDE DE 850C. LOS AGENTES FILTRANTES DIATOMITICOS CALCINADOS OBTENIDOS TIENEN UN CONTENIDO DE CRISTOBALITA MENOR QUE 1,5%, UNA PERMEABILIDAD COMPRENDIDA ENTRE 20 Y 500 MILIDARCYS, UNA DENSIDAD DE TORTA INFERIOR A 0,400 G/CM3 Y UN RECHAZO SOBRE EL TAMIZ DE 50 MIM INFERIOR A 15%.
