Production of paper/cardboard fibers uses a biological process stage for the wood chips, using a fungus action to give cellulose, which is processed by chemical precipitation reaction and augmented with additives

摘要

Production of fibers, for the production of paper or cardboard webs, wood chips (S1) are broken down in a biological process (S2) by a fungus action. The wood material is stored for a given time, e.g. two weeks, under controlled temperature and air circulation conditions, to encourage fungal growth. Production of fibers, for the production of paper or cardboard webs, wood chips (S1) are broken down in a biological process (S2) by a fungus action. The wood material is stored for a given time, e.g. two weeks, under controlled temperature and air circulation conditions, to encourage fungal growth. The cellulose produced by the biological process is passed through a chemical precipitation reaction stage, and enriched with additives e.g. calcium carbonate after the pulper stage (S5) using a Fiber Loading process.
