摘要
讨论了中国造纸原料的现状和问题,合理利用草类原料的必要性,进一步扩大利用草类原料的问题和对策。论述了草类纤维特性与木材的差异,以及造成其制浆造纸工艺与方法等一系列特殊性,这种差异主要表现在:禾草类纤维生物结构和化学组成的不均匀性造成其制浆过程和产品的特殊性;草类纤维木质素结构的特性,造成草类纤维的制浆过程与木材制浆的差异;草类木质素在纤维细胞中分布特征,造成草类纤维与木材制浆脱木质素局部化学特性的差异;草浆蒸煮黑液的物理化学特性,造成草浆碱回收困难。
The present situation and problems of China＇ s paper making raw material, the necessity of rationally utilizing straw and the problem and strategy of further expanding the utilization of straw are discussed in the paper. The paper describes the difference between the characteristics of straw fiber and that of timber and the specialties in the technology and methods of straw pulping and papermaking therewith. The major differences are： the non-uniformity of the organic texture and chemical composition of grass fiber resulting in the specialties of the pulping process and its products; the structural characteristics of lignin of straw fiber resulting in the difference between the pulping process of straw fiber and that of timber; the distribution characteristics of straw lignin in the fibrous cell causing the difference of the local chemical characteristic of delignification between the pulping of straw fiber and that of timber and the physicochemical characteristics of black liquor of straw pulp cooking causing the difficulty in straw pulp alkali recovery.
