摘要: 研究厚壁巨龙竹秆材的化学成分、纤维形态及基本密度等材性特征。材性特征研究显示,厚壁型巨龙竹秆材中不同部位的基本密度、化学成分及纤维形态存在一定的差异。其平均基本密度为0.68 g/cm3,属中等密度材;化学组成平均为:综纤维素71.01%、木质素26.12%、多戊糖15.96%;其纤维的平均长度2.19 mm、宽度19.61 μm、长宽比值111、壁腔比值1.78。总体上看,厚壁型巨龙竹的基本密度适中、综纤维素含量较高、纤维形态较为优良,可以满足造纸工业对原料的基本要求。

Abstract: The basic density,component contents,and fiber morphology of bamboo culm (Dendrocalamus sinicus L.C.Chia et J.L.Sun) were analysed in this paper.The results indicated that these properties shown a certain amount of difference in different parts of bamboo culm.The basic density of the bamboo culm was 0.68 g/cm3,which was in the middle level among lignocellulosic biomass.In addition,the contents of holocellulose,lignin and pentosane were 71.01%,26.12% and 15.96%,respectively.The fiber length,fiber width,length/width ratio,and wall thickness/fiber lumen diameter ratio of the bamboo culm were 2.19 mm,19.61 μm,111 and 1.78,respectively.Overall,D.sinicus is one of qualified materials for pulping and papermaking due to its modest basic density,higher holocellulose content and better fiber morphology compared with other common fibrous raw materials.
