摘　　要：对杨木PRC-APMP进行了纤维筛分分级制取细小纤维试样,对比探讨了DDJ与SWECO圆形振动筛两种细小纤维筛分的特性。结果表明:不同分级设备细小纤维筛分收益率均随着筛网目数的增加而下降,但SWECO细小纤维的筛分收益率明显高于DDJ细小纤维。DDJ细小纤维具有更高的表面电荷量、更高的扭结指数、卷曲程度和更多的丝状组分,而SWECO细小纤维具有更高的黏度、更高的纤维束含量。Poplar PRC-APMP fiber was classified to prepare fines sample, the properties of which collected by SWECO Vibro-Energy Round Separator and collected by DDJ were comparatively investigated. The results show that the yielding rate of fines for different classifiers decreases with the increase of screen meshes, while the yielding rate of the fines by SWECO Vibro-Energy Round Separator is remarkably higher than that of fines by DDJ. Furthermore the DDJ fines are higher in surface charge, kink index, curl level and fibril components than the SWECO fines, but SWECO fines are higher in viscosity and more in fiber bundles content.
