中文摘要:

      对出一段高浓磨浆的化学机械浆粗浆进行筛分以得到纤维束，并采用选择性磨浆工艺对纤维束进行磨浆，研究了纤维束的预处理对化学机械浆磨浆性能及成纸性能的影响。结果表明，在选择性磨浆的基础上对纤维束进行化学预处理能够进一步降低磨浆能耗，并且能够使磨浆后纤维的完整性得到较好的保持，成纸松厚度较高。

Abstract:

      Fiber bundles were fractionated out of the chemimechanical pulps which came from the first refining stage, and refined with the selectively refining process. This paper studied the effect of fiber bundles pretreatment on refining performance and the resultant paper properties of the prepared chemimechanical pulp. The results showed that the pretreatment of fiber bundles could further reduce the refining energy. Besides, the pulp could maintain more intact fibers after refining, and the resultant paper could have better bulk property.
