生物酶处理麦草浆对湿部电荷特性的影响

Effect of Enzyme Treatment on the Wet-end Charge Characteristics of Wheat Straw Pulp

采用各种生物酶对漂白麦草浆进行处理,研究酶处理后麦草浆纤维特性及浆料湿部电荷特性的变化。另外研究了酶处理浆对阳离子聚丙烯酰胺吸附特性的影响。结果表明,经过生物酶处理后的浆料,纤维的平均长度稍有增加,细小纤维含量明显降低,浆中溶解电荷及Zeta电位、聚电解质的吸附量及纸页强度均有降低但变化不大。

The paper mainly studied the effect of enzyme treatment on the wet-end charge characteristics of the bleached wheat straw pulp.Charge characteristics of the wheat straw pulp,as well as the fiber properties by enzyme treatment were evaluated.Then Zeta potential of pulp,dissolved charges and the adsorption of cationic polyacrylamide were discussed.The results demonstrated that biological enzyme treatment contributed to increase of fiber average length and the fall of fine content.However,dissolved charges and...
