摘要:为探索改善CTMP制浆过程化学预浸渍效果的可能途径,实验考察了在CTMP制浆过程化学预浸渍段添加渗透剂对制浆性能的影响。实验结果表明,在化学预浸渍段添加渗透剂后,CTMP浆纤维平均长度提高,长度分布更加集中,集中区域向较高的长度区间移动,成浆纤维束和细小纤维含量有明显下降,浆张白度、松厚度、抗张指数、撕裂指数均有不同程度提高,磨浆电耗有所降低。 |
Abstract:In this paper, in order to find a feasible way to enhance the preimpregnation effectively, the effect of penetrant application in preimpregnating stage of CTMP process was studied. It was found that, compared to the control sample, the sample with using penetrant has longer mean length of CTMP fiber, and the fiber length distribution is more concentrated to a region with longer length value. The shives and fines are decreased significantly, while the whiteness, bulk, tensile index and tear index are improved in various degrees with a lower refining energy consumption. |
