Abstract

SE PRESENTA UN COMPUESTO DESARROLLADOR DE COLOR PARA SU USO EN CONJUNTOS DE PAPEL COPIADOR (SIN CARBON) SENSIBLES A LA PRESION QUE COMPRENDE UN EXTENDEDOR DE UN PIGMENTO INORGANICO (POR EJEMPLO CAOLIN, TALCO O CAOLIN CALCINADO) Y UN COMPUESTO DE SILICE HIDRATADA / ALUMINA HIDRATADA. EL COMPUESTO SE PRODUCE PRECIPITANDO LA MEZCLA DE SILICE HIDRATADA / ALUMINA HIDRATADA EN LA PRESENCIA DEL EXTENDEDOR MEDIANTE LOS PASOS SIGUIENTES: A) LA ADICION GRADUAL DE UNA SOLUCION DE SILICATO DE METAL A UNA SOLUCION DE SAL DE ALUMINIO QUE TIENE UN PH INICIAL POR DEBAJO DE 4 HASTA QUE EL PH DE LA MEZCLA RESULTANTE SEA APROXIMADAMENTE 4, MEDIANTE LO CUAL SE INDUCE UNA PEQUEÑA PRECIPITACION Y SE FORMA UN COLOIDE EN SUSPENSION; B) LA ADICION GRADUAL DE ALCALI A DICHO COLOIDE HASTA ELEVAR EL PH HASTA APROXIMADAMENTE 7, MEDIANTE LO CUAL SE INDUCE UNA POSTERIOR PRECIPITACION Y LA GELIFICACION DEL COLOIDE, DICHO COLOIDE GELIFICADO ES UNA MEZCLA DE SILICE HIDRATADA / ALUMINA HIDRATADA; C) LA SEPARACION DEL PRODUCTO RESULTANTE DEL MEDIO ACUOSO Y EL LAVADO PARA SEPARAR LAS SALES DISUELTAS Y, D) EL SECADO DEL PRODUCTO LAVADO Y SU REDUCCION HASTA UN TAMAÑO DE PARTICULA.
