摘要: A process in which phenolic substances, particularly lignin sulfonate, are used to produce a binder for wood materials. The phenolic substance is activated by displacing it with enzymes. Phenolic groups of the phenolic substance become oxidatively polymerized by a radical mechanism, so that the phenolic substance is changed into an active binder.
