用高锰酸钾对工业用漂白针叶木浆和蔗渣浆进行了处理。结果表明,当高锰酸钾用量为0.25%～2%(相对于绝干浆)时,漂白浆的裂断长及白度均有较大程度的提高。这些性能的改善与纸浆聚合度及α-纤维素的含量有关。由于高锰酸钾还具有杀菌和消毒作用,因此采用高锰酸钾处理后的漂白浆可以避免其在运输和贮存过程中发生不良反应,进而减少纸浆损失。
Industrial bleached softwood pulp and bagasse pulp were treated with potassium permanganate. The results showed that when the amount of potassium permanganate was 0.25% ~ 2% (relative to the absolute dry pulp), bleached pulp crack length and whiteness have a greater increase. These properties are related to the degree of polymerization of the pulp and the content of α-cellulose. Since potassium permanganate also has bactericidal and disinfecting effects, bleaching pulp treated with potassium permanganate can avoid its adverse reactions during transportation and storage, thereby reducing pulp loss.
