"GB/T 1546-2004 Pulp, Determination of Kappa Value" specifies the determination method of Kappa value of pulp. The standard specifies the test principle, equipment, reagent requirements and operation procedures. The content of uncooked or unbleached organic matter in pulp is determined by oxidation reduction reaction, and the amount of residual lignin and other reducing substances in pulp is quantified by Kappa value. The standard provides a scientific basis for evaluating the degree of pulp cooking and bleaching, and controlling the pulping process, helping to ensure the mass and production efficiency of pulp.
