纸浆 细小纤维质量分数的测定
Application Summary AI generated
This standard specifies a method for determining the mass fraction of fines in pulp suspensions, using a fractionation apparatus to separate particles smaller than 200 mesh (76 μm). It is applied in the pulp and paper industry for quality control during pulp production, process optimization, and raw material evaluation, particularly for assessing the impact of fines on paper formation, drainage, and strength properties.
