Abstract
resumo pré-floculação de enchedores usados na fabricação de papel um método de preparar uma dispersão estável de partículas de enchedor floculadas para o uso em processos de fabricação de papel compreende o uso de micropartícula antes, simultaneamente, e/ou depois da adição de um primeiro agente de floculação a uma dispersão aquosa de partículas de enchedor, seguido por adição de um segundo agente de floculação à dispersão e cisalhamento opcional adicional dos flocos de enchedor resultantes ao tamanho de partícula desejado resultando em flocos de enchedor resistentes a cisalhamento com uma distribuição de tamanho definida e controlável. além disso, um coagulante neutralizante pode ser adicionado à dispersão para parcial ou completamente neutralizar a carga do enchedor antes que a micropartícula e/ou o primeiro agente de floculação são adicionados.
