Abstract

UN MATERIAL REVELADOR DE COLOR SE OBTIENE: A) AÑADIENDO GRADUALMENTE UNA DISOLUCION DE SILICATO METALICO A UNA DISOLUCION DE SAL DE ALUMINIO QUE INICIALMENTE ESTA A UN PH MENOR DE 4 HASTA QUE EL PH DE LA MEZCLA RESULTANTE ES 4 APROXIMADAMENTE, PARA ASI INDUCIR ALGUNA PRECIPITACION Y FORMAR UN SOL; B) AÑADIENDO GRADUALMENTE ALCALI A DICHO SOL PARA AUMENTAR EL PH A APROXIMADAMENTE 7, PARA ASI INDUCIR UNA PRECIPITACION ADICIONAL Y GELIFICAR EL SOL O GELIFICAR AUN MAS EL SOL, TENIENDO DICHO SOL GELIFICADO UN COMPUESTO DE SILICE HIDRATADAÑALUMINA HIDRATADA; C) SEPARANDO EL GEL DEL MEDIO ACUOSO Y LAVANDO EL PRODUCTO RESULTANTE PARA RETIRAR LAS SALES DISUELTAS; Y D) SECANDO EL PRODUCTO LAVADO Y REDUCIENDOLO A TAMAÑO PARTICULA. ESTE MATERIAL REVELADOR DE COLOR SE FORMULA A CONTINUACION EN UN COMPUESTO DEL REVESTIMIENTO, SE APLICA A UNA BASE DE PAPEL Y SE SECA PARA CREAR UN MATERIAL DE GRABACION REVELADOR DE COLOR COMO SE UTILIZA EN JUEGOS DE PAPEL DE COPIA (SIN CARBON) SENSIBLE A LA PRESION.
