对漂白针叶木浆进行了纤维筛分分级制取细小纤维试样，对比探讨了DDJ和SWE-CO圆形振动筛两种细小纤维筛分的特性，并且与标准纤维进行配抄，研究了不同细小纤维添加量对纸张性能的影响。实验结果表明：SWECO 细小纤维收益率明显高于DDJ细小纤维；DDJ细小纤维具有较高的表面电荷，而SWECO 细小纤维具有较高的粘度、比沉降容积；与DDJ细小纤维相比，SWECO细小纤维更能减少纸张的松厚度和透气度，增强纸张的强度。

The chemical pulp fiber was classified to prepare fines sample ,the properties of which collected by SWECO Vibro-Energy Round Separator and collected by DDJ were com-paratively investigaed .And It was used to make paper with standard fibers ,different dosage of fines on the properties of paper was studied .The results show that SWECO Vibro-Energy Round Separator is remarkably higher than that of fine by DDJ .Furthermore ,the DDJ fines are higher in surface charge ,the SWECO fines are higher viscosity and sedimentation vol-ume .Compared with the DDJ fines ,SWECO fines have reduced the bulk and porosity ,in-creased the strength of the paper .

选用杨木P-RC APM P为原料，打浆至68°SR后利用SWECO圆形振动筛筛分出三个类别（P200、P300、P400）的细小纤维，观察其形态，测定黏度、比沉降容积、表面电荷等参数，研究了不同P-RC APM P细小纤维筛分组分对纸张性能的影响。结果表明：筛网目数越高，所得细小纤维的表面电荷、粘度和丝状组分含量越高。筛网目数越高的细小纤维，所得纸张的松厚度、透气度和不透明度越低，而强度性能越高。

Poplar P-RC APM P was beated to 68 °SR for generating fines and SWECO was used for collecting fines (P200 ,P300 ,P400) ,its morphology ,viscosity ,relative sediment volume ,surface charge were studied ,the effects of different P-RC APM P fines sub-fractions on handsheet properties were studied .The result showed that ,the surface charge ,viscosity and relative sediment volume of fines which classified on SWECO would increased with the increasing screen meshes .The higher density of screen meshes is ,the lower of handsheet bulk ,air permeability and opacity are .
