"GB/T 2677.8-1994 Determination of acid-insoluble lignin content in papermaking raw materials" stipulates the determination method of acid-insoluble lignin content in papermaking raw materials. The standard clarifies the determination principle, instrument reagents, sample processing flow and calculation method, and separates acid-insoluble lignin through specific acid treatment raw materials. It provides a unified specification for accurately evaluating the content of acid-insoluble lignin in papermaking raw materials, and is an important basis for controlling the mass of raw materials and guiding the papermaking process.
