INFLUENCE OF XYLANASE TREATMENT ON REFINING OF P-RC APMP PULP OF ITALIAN BLACK POPLAR BRANCHES
Xylanase pretreatment before the second refining stage during P-RC APMP process of Italian black poplar branch wood can reduce the refining energy consumption by 3％~8％ and the following beating energy consumption by 5％~9％. And brightness of the pretreated pulp was improved by 1.0％~2.3％ISO with minor change of pulp strength properties. Xylanase pretreatment before the third refining stage can reduce the refining energy consumption by 4％ ~ 8％ and the following beating energy consumption by 5％~13％. And brightness of the pretreated pulp was improved by 1.0％ISO~2.3％ISO with minor improvement of pulp strength properties. The application of xylanase before the third refining stage is better than that before the second refining stage. Effect of xylanase AU-PE89 treatment on energy saving was better than that of xylanase 51024 treatment, and the optimal dosage of xylanases AU-PE89 was 20IU·g-1.
