| 摘 要： | 通过正交实验和单因素实验研究了本色废纸浆氧脱木素前高锰酸钾预处理的影响因素及其对纸浆的作用。结果显示,pH值和高锰酸钾用量是预处理的主要影响因素。高锰酸钾具有脱木素和活化木素结构的双重作用,可以提高氧脱木素的选择性,预处理后残留在纸浆中的Mn~(2 )对氧脱木素影响很小。

| Abstract: | Potassium permanganate pretreatment and oxygen delignification of old kraft paper were studied. The Onhogonal test and single factor test indicated that the main factors influencing the pretreatment are potassium permanganate charge and pH value. It was found that the pretreatment has two functions, one is delignification, and the other is lignin activation. The optimum conditions of pretreatment are potassium permanganate charge 0.5%, pH value 4-5. Oxygen delignification test showed that the pretreatment is favorable to oxygen delignification and improve oxygen delignification selectivity, resulting in greater reduction of Kappa number, and minor effects on pulp viscosity. |
