ActivePulps--Method for determination of copper number
纸浆铜价的测定
Application Summary AI generated
This standard specifies the method for determining the copper number in pulps, which measures the reducing power of cellulose and indicates the degree of degradation or oxidation. It is applied in the paper and pulp industry for quality control of raw materials and finished products, particularly in testing pulps used for specialty papers, electrical insulation, or chemical derivatives where cellulose purity is critical. The method is used in laboratory settings to assess pulp aging, bleaching effectiveness, or damage from processing.
