摘　　要：选用杨木P-RC APMP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 APMP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 APMP 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 APMP 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.
