纸浆 丙酮可溶物的测定
Application Summary AI generated
This standard specifies a method for determining the acetone-soluble matter content in pulps, which includes resins, fatty acids, and other organic extractives. It is applied in the pulp and paper industry for quality control and raw material evaluation, particularly when assessing pulps used in manufacturing high-purity paper products or chemical derivatives where residual extractives can affect processing or end-use properties. The test is relevant for both virgin and recycled pulps in laboratory and production testing contexts.
