回顾了机械浆磨浆过程中纤维分离与分丝帚化的相关研究,分别介绍了纤维分离与分丝帚化过程、纤维分离和分丝帚化模式、纤维分离与分丝帚化机理、纤维分离和分丝帚化对磨浆温度和磨浆能量消耗的影响,以及纤维分离对浆料品质的决定性作用。通过回顾这些研究,了解到纤维分离与分丝帚化同时发生于磨浆过程中,劈开、滑移和撕裂是纤维分离与分丝帚化的3种模式;此外,还可以了解纤维断裂的3种模式。虽然纤维分离与分丝帚化机理迄今尚未研究清楚,但S2层微纤丝角所决定的S2层变化仍是关键因素。通过回顾可知,大部分能量消耗于纤维分丝帚化,少部分消耗于纤维分离和温度升高。最后,总结了纤维分离对浆料品质的重要作用。
In this paper, the researches on fiber separation and broom brooming in mechanical pulp refining are reviewed. The fiber separation and billet brooming, the fiber separation and billet brooming, the fiber separation and billet brooming, the fiber The effect of separation and partial brooming on refining temperature and refining energy consumption, and the decisive effect of fiber separation on the quality of the slurry. By reviewing these studies, we know that the three modes of fiber separation and strand-brooming are the cleavage, slippage and tearing of fiber separation and broom broom simultaneously with the refining process. In addition, fiber breakage The three modes. Although the mechanism of fiber separation and strand broom has not been studied yet, the change of layer S2 determined by S2 microfibril angle is still the key factor. From the review, we can see that most of the energy consumption in the fiber billet broom, a small part of the consumption of fiber separation and temperature rise. Finally, the important role of fiber separation on pulp quality is summarized.
