Abstract

resumo “pretratamento de carregamento para melhorar desempenho de auxiliar de resistência do papel na fabricação de papel" a invenção diz respeito a métodos, composições e aparatos para aumentar a resistência de papel feito de um carregamento tendo uma grande proporção de occ. método envolve as seguintes etapas: 1) fornecer um carregamento de papel tendo uma grande quantidade de occ nele, 2) adicionar promotor de resistência à carregamento antes de adicionar um agente de resistência à carregamento, 3) adicionar um agente de resistência à carregamento e 4) preparar um produto de papel a partir do carregamento. este método permite que material occ barato seja usado em um processo de fabricação de papel sem os problemas de qualidade que o lixo aniônico em occ tipicamente causa. assim, produtos de papel tendo baixos custos e alta qualidade podem ser produzidos.
