PROCEDURE FOR THE PRODUCTION OF PULP

摘要

74131-1 Disclosed is a procedure for the production of mechanical pulp from a fibrous product. To reduce a refining energy, the fibrous product is subjected to an enzyme treament in which an enzyme acts on lignin in the fibrous product. When oxidizing enzymes are used, it is preferable to adjust the redox potential to the optimum level characteristic of each oxidation-reduction enzyme by means of suitable oxidation-reduction chemicals. In addition to reducing the refining energy consumption, the enzyme treatment also improves the strength properties and the blue reflectance factor of the pulp.
