纤维素酶处理对麦草APMP浆性能的影响
Effects of Cellulase Treatment on Wheat Straw APMP
摘要
Abstract
Physical properties of alkline peroxide mechanical pulp (APMP) of wheat straw were modified by cellulase. The fiber morphology and cellulose crystallinity before and after treatment with cellulase were analyzed by fiber quality analyzer ( FQA),environment seanning electron microscope (ESEM) and X-ray diffraction (XRD).The results showed that the optimal treatment conditions are temperature 60℃,cellulase dosage 6 IU/g and pH value 5.0 - 6.0. Compared with the control pulp, tearing index, tensile index, burst index and density of the treated pulp increase by 7.6%, 9.3%, 15.1% and 10.1% respectively. The fines content of the pulp treated by cellulase decrease, and the length, kink index and curl index of the treated fiber increase. ESEM results revealed that the smoothness and the softness of the treated fiber are improved.From XRD analysis. the crystallinity of the treated fiber increase by 3.14%. The results showed that cellulase treatment has an obious influence on fiber morphology and physical properties of the pulp.关键词
