摘要
对巨菌草的生物结构和化学组分进行分析,并对巨菌草的硫酸盐法制浆性能进行了初步研究。结果显示:巨菌草具有禾本科生物结构的显著特点,含有薄壁细胞、导管和纤维组织带;巨菌草的纤维平均长度为0.91 mm,宽度为21.1μm,长宽比值为43.3,壁腔比为0.8;巨菌草的硝酸-乙醇纤维素含量达39.09%,而酸不溶木素(12.03%)、聚戊糖(22.75%)和灰分(5.9%)含量相对较低,这些特点使其易于蒸煮,化学药品消耗低,制浆得率高,容易打浆,是比较适合制浆造纸的非木材纤维原料;巨菌草的硫酸盐法制浆造纸性能良好,抄片的裂断长为2.73 km,撕裂指数为11.568 m N·m^2·g^(-1),耐破度为1.846 kPa·m^2·g^(-1)。
The biological structure and KP pulp properties of Pennisetum Sinese were studied. Results of fiber morphology analysis are as follows： average fiber length is 0.91 ram, fiber width is 21.1 μm, fiber length-width ratio value is 43.3, fines content is 12.23%. Results of chemical composition are as follows： nitro-ethanol celluloses is 39.09%, the acid insoluble lignin （12.03%）, pentosan （22.75%） and ash content （5.9%） are relatively low. ＂Ihese features make it easy for cooking, low chemical consumption, high pulping yield and easily beating.The results show that the KP pulp strength properties of the Pennisetum Sinese Grasses are perfect. So Pennisetum Sinese is more suitable for pulp and papermaking.
