What are the applications of lignin powder? Industrial lignin comes from papermaking waste liquid. The lignin extracted by acidification at room temperature usually has larger particles and needs to be processed into powder by a lignin Raymond mill in order to be well used. For example, in the rubber industry, fine-particle lignin compounds have a reinforcing effect in both NR and NBR, and the degree of reinforcement for NR is greater. In addition, lignin powder can also be used as coupling agent and reinforcing agent for rubber, dispersant for dyes, viscosity reducer for drilling mud, desulfurizer for industrial waste gas, etc.
