Abstract

MEZCLANDO DOS TIPOS DE PARTICULAS FORMADORAS DE HIDROGEL CON DISTINTOS VALOES DE ABSORCION CONTRA PRESION, SE PUEDE OBTENER UN EFECTO SINERGISTICO, EN EL QUE EL VALOR AAP DE LA MEZCLA ES MAYOR DEL QUE SE PODRIA ESPERAR EN BASE A LAS FRACCIONES DE PESO DE LOS COMPONENTES DE LA MEZCLA. MEZCLANDO DOS TIPOS DE PARTICULAS FORMADORAS DE HIDROGEL CON DISTINTOS VALORES CAPACIDAD CENTRIFUGA DE BOLSA DE TE, Y VALORES AAP IGUALES, SE OBSERVA UN INCREMENTO INESPERADO EN EL VALOR AAP DE LA MEZCLA. UN METODO DE FABRICACION DE MATERIAL GELIFICANTE DE ACUERDO CON EL INVENTO, CONSTA DE LOS SIGUIENTES PASOS: - PROPORCIONAR UN PRIMER TIPO DE MATERIAL FORMADOR DE HIDROGEL, Y UN SEGUNDO TIPO DE MATERIAL FORMADOR DE HIDROGEL; - INTRODUCIR LOS DOS TIPOS DE MATERIAL FORMADOR DE HIDROGEL EN UN MECANISMO DE MEZCLADO; Y - MEZCLAR LOS DOS TIPOS DE PARTICULAS FORMADORAS DE HIDROGEL PARA FORMAR LA MEZCLA. LOS DOS TIPOS DE MATERIAL FORMADOR DE HIDROGEL PUEDEN SER FORMADOS MEDIANTE UN PROCESO DE POLIMERIZACION SEPARADO ENLOTES SEPARADOS, SEGUIDO DEL MEZCLADO DE LOS DOS TIPOS DE PARTICULAS FORMADORAS DE HIDROGEL. ALTERNATIVAMENTE, UNA FRACCION DE PESO DE UN SOLO TIPO DE MATERIAL FORMADOR DE HIDROGEL, PUEDE SER SEPARADA DEL VOLUMEN DEL MATERIAL, PUEDE SER TRATADA SUBSECUENTEMENTE PARA INCREMENTAR EL VALOR AAP DE LA MISMA, Y PUEDE SER MEZCLADA DE NUEVO EN EL VOLUMEN DEL MATERIAL.
