Abstract

"ABSORVENTE DE áGUA PARTICULADO CONTENDO RESINA ABSORVENTE DE áGUA COMO PRINCIPAL COMPONENTE E ARTIGO SANITáRIO PARA ABSORVER UM FLUìDO CORPORAL". compreendendo um absorvente de água particulada contendo uma resina absorvente como componente principal, a resina absorvente sendo um polímero de ligação cruzada de um monómero não saturado solúvel em água; a resina absorvente possui um formato particular e contém partículas de um tamanho de partícula em uma faixa de no mínimo 106 <109>m e no máximo 850 <109>m em uma quantidade de no mínimo 90 porcento de massa, com respeito à massa total da resina absorvente contida no absorvente de água particulada; o absorvente de água particulada possui um primeiro índice de absorção de concentração de sal de no mínimo 0,60, conforme medido pela fórmula (1) abaixo, quando é usada a água da troca de íons como uma solução aquosa de uma concentração de sal constante: (índice de absorção de concentração de sal) = (capacidade de absorção contra uma pressão de 4,83 kPa com respeito à solução aquosa de uma concentração de sal constante)/(capacidade de absorção na ausência de pressão com respeito à solução aquosa de uma concentração de sal constante) ...(1).
