Methods of test for pulp and paper - Kappa number of pulp

AS/NZS 1301.201s-2002 发布历史

This method provides an indirect measure of the relative bleachability, or residual lignin content of pulp. It may be used for all types and grades of chemical and semi-chemical unbleached and semi-bleached wood pulps obtained in yields under 60%. The method may also be used as a laboratory control technique for well screened pulps obtained in higher yields up to 70%. It should be noted that reproducibility is less for high yield pulps than for low yield pulps.
