摘要
介绍了共 7种预处理纤维素浆粕的化学和物理方法 ,阐明了各种方法的作用机理 ,并分别探讨了对纤维素微细结构及反应性能的影响 ,也分析了各种方法的工业使用状况及其发展前景 .
This paper introduces the methods of pre treatment of cellulose with chemical and physical means.These are sodium hydroxide activation (alkali smmersing),EDA Pre treatment,liguid anammonia activation,enzyme activation,electron beam activation,ball grinder pre treatment and steam explosion activation.This article demostrates the reaction mechanism of these methods.Different pretreatment methods have different effects on cellulse fine structures and reaction behaviours.Here we summarize the recent achievements of pretreatments of cellulose and try to predict the direction of research.
