Study on Preparation of Composite Enzyme for Beating of Neosinocalamus affinis Pulp and Its Effects on Beating Performance
摘要
Abstract
To address the issues of high beating energy consumption and poor beating performance in the pulping process of Neosinocal-amus(N.)affinis,this study focused on the research of composite enzyme preparations for enzymatic beating process of N.affinis chemi-mechanical pulp and chemical pulp,aiming to enhance the beating performance and reduce beating energy consumption.Ultimately,composite enzyme suitable for N.affinis chemimechamical pulp and chemical pulp were developed.The composite enzyme for chemime-chanical pulp consisted of 20 U/g xylanase,35 U/g mannanase,and 10 U/g lytic polysaccharide monooxygenase(LPMO),while that for chemical pulp consisted of 20 U/g xylanase,20 U/g ferulic acid esterase,and 4 U/g LPMO.After treatment with the composite enzyme,the beating degree of N.affinis chemimechanical pulp and chemical pulp increased by 16.0%and 11.9%,respectively,and the beating energy consumption decreased by 26.1%and 20.6%,respectively.Furthermore,the tensile index and burst index of paper made from N.affinis chemimechanical pulp and chemical pulp were significant-ly improved,specifically,the tensile index and burst index of chemimechanical pulp paper increased by 20.9%and 13.6%,re-spectively,while those of chemical pulp paper increased by 5.7%and 1.3%,respectively.It was found that the kink index,water re-tention value,and fibrillation degree of N.affinis fibers increased af-ter enzyme treatment.关键词
