thin walled fiber

The fiber momhology observed on SEM ( Scanning Electromicroscope) are evi-dently superior than old plate when beating the thick-wall fiber, Yunnan pine kraft highyield chemical pulp using Φ450 YG02 type new refiner plate, it can be able to affordmore external and internal microfibril and resulting to take a important role of upgrad-ing the quality of sack paper.

采用Φ４５０Ｙ６０２型新磨片对厚壁纤维云南松硫酸盐高得率化学浆进行打浆后，用扫描电镜（ＳＥＭ）观察到的纤维形态和老磨片相比，能产生较好的表面和内部细纤维化，对改善和提高纸袋纸质量起了重要作用。
