| 摘要 |
The present invention relates to a mechanical pulp production from a fibrous material, such as whole logs, chips, shavings or pulp ground in a single or several stages. For the purpose of lowering the specific energy consumption, the method uses enzyme treatment of the fibrous material. The invention is implemented by treating the fibrous material with an enzyme mixture consisting of hydrolytic and oxidizing enzymes whose redox potential level is adjusted to a value below 200 mV. |
