Abstract

UN ELEMENTO ABSORBENTE QUE CONSTA DE AL MENOS UNA REGION CON UN MATERIAL ABSORBENTE EN UNA CONCENTRACION DE APROXIMADAMENTE 60 A 100% POR PESO. EL MATERIAL ABSORBENTE TIENE PROPIEDADES FISICAS MEJORADAS DESPUES DE HINCHARSE Y CONSTA DE UNA MEZCLA DE (1) VARIAS PARTICULAS ABSORBENTES GELIFICANTES FORMADAS POR UN POLIMERO INSOLUBLE EN AGUA E HINCHABLE CON AGUA Y (2) UN POLIMERO MODIFICADO CON PROPIEDADES ABSORBENTES QUE REACCIONA CON AL MENOS UN COMPONENTE INCLUIDO EN UREA. AL APLICAR UREA AL MATERIAL ABSORBENTE, LAS PARTICULAS ABSORBENTES GELIFICANTES SE UNEN ESPONTANEAMENTE A TRAVES DEL POLIMERO CON PROPIEDADES ABSORBENTES MODIFICADAS. EL MATERIAL ABSORBENTE TIENE AL MENOS UNA DE LAS SIGUIENTES PROPIEDADES MEJORADAS DESPUES DE HINCHARSE: (1) PERMEABILIDAD A LIQUIDOS, (2) POROSIDAD (3) INTEGRIDAD HUMEDA Y (4) PROPIEDADES DE RECUPERACION AL SER SOMETIDO A FUERZAS EXTERNAS.
