ActivePulp—Determination of alkali solubility
纸浆 碱溶解度的测定
Application Summary AI generated
This standard specifies the method for determining the solubility of pulp in sodium hydroxide solutions, primarily used to assess the degradation and purity of cellulose fibers. It is applied in the pulp and paper industry for quality control of raw materials and finished products, particularly in evaluating the chemical processing effects on pulps like dissolving pulps. The test is critical for manufacturers producing high-purity cellulose derivatives, such as viscose or cellulose acetate.
