Abstract
SE REFIERE A UN METODO DE FABRICACION DE UNA ARCILLA, POR EJEMPLO UNA ARCILLA DE BENTONITA, PARA USAR EN UN REVESTIMIENTO DE ARCILLA GEOSINTETICA U OTROS SISTEMAS DE BARRERA PARA EL MANEJO DE DESECHOS DE LIQUIDO ALCALINO, QUE COMPRENDE SU MODIFICACION MEDIANTE LA ADICION A LA ARCILLA DE UN COMPONENTE DE SILICE QUE CONTIENE SILICE LIBRE O UN MATERIAL SILICEO, EN DONDE EL SILICE LIBRE O EL MATERIAL SILICEO PUEDE ANADIRSE EN FORMA SECA, POR EJEMPLO EN FORMA DE POLVO, O EN FORMA ACUOSA, POR EJEMPLO EN FORMA DE UNA SUSPENSION COLOIDAL ESTABLE. SE REFIERE ADEMAS, A UN METODO PARA PRODUCIR UNA BARRERA DE ARCILLA A UNA SOLUCION ALCALINA QUE COMPRENDE: A) ANALIZAR EL CONTENIDO DE SILICE LIBRE DE LA ARCILLA; B) COMPARAR EL CONTENIDO DETERMINADO, CON UN VALOR OBJETIVO ASOCIADO CON LA RESISTENCIA ALCALINA; C) PONER EN CONTACTO LA ARCILLA CON EL ANALISIS DE SILICE LIBRE ACEPTABLE SOBRE 5% A 10% POR PESO DE SILICE, CON UNA SOLUCION ALCALINA; Y D) EMPLEAR LA ARCILLA CONTACTADA, CON EL ANALISIS DE SILICE LIBRE ACEPTABLE, COMO UNA BARRERA A LAS SOLUCIONES ALCALINASREFERS TO A METHOD OF MANUFACTURING A CLAY, FOR EXAMPLE A BENTONITE CLAY, TO BE USED IN A GEOSYNTHETIC CLAY COATING OR OTHER BARRIER SYSTEMS FOR THE MANAGEMENT OF ALKALINE LIQUID WASTE, WHICH INCLUDES ITS MODIFICATION BY ARIF OF A SILICA COMPONENT CONTAINING FREE SILICA OR A SILICA MATERIAL, WHERE THE FREE SILICA OR SILICA MATERIAL MAY BE ADDED IN A DRY FORM, FOR EXAMPLE IN POWDER FORM, OR IN AQUEOUS FORM, FOR EXAMPLE IN THE FORM OF A COLLOIDAL SUSPENSION . IT ALSO REFERS TO A METHOD TO PRODUCE A CLAY BARRIER TO AN ALKALINE SOLUTION THAT INCLUDES: A) ANALYZING THE CONTENT OF FREE SILICA OF THE CLAY; B) COMPARE THE DETERMINED CONTENT, WITH AN OBJECTIVE VALUE ASSOCIATED WITH THE ALKALINE RESISTANCE; C) PUT IN CONTACT THE CLAY WITH THE ANALYSIS OF ACCEPTABLE FREE SILICA ABOVE 5% TO 10% BY WEIGHT OF SILICA, WITH AN ALKALINE SOLUTION; AND D) USE CONTACTED CLAY, WITH ANALYSIS OF ACCEPTABLE FREE SILICA, AS A BARRIER TO ALKALINE SOLUTIONS
