【摘要】 通过对版纳甜龙竹的化学成分、纤维形态、成浆性能的研究,结果表明:版纳甜龙竹灰分1.80%,SiO20.50%,冷水抽提物3.10%,热水抽提物4.42%,苯-醇抽提物2.65%,1%NaOH抽提物17.24%,木质素16.67%,多戊糖25.43%,纤维素50.55%;纤维平均长度、宽度、长宽比分别为3.79mm、14.83μm、255.56;与造纸工业目前使用较多的慈竹、毛竹、云杉、马尾松、桉树等相比较,具有纤维平均长度较长、长宽比较高、纤维素含量较高、木质素含量较低的优势;该竹易于成浆,与针叶木比较撕裂强度较高,是一种优良的竹类纤维原料。更多还原

【Abstract】 An experiment was carried out to study the chemical composition, fiber morphology and pulping properties of Dendrocalamus hamiltonii Nees et Arn.ex Munro. The results show that the chemical compositions of Dendrocalamus hamiltonii Nees et Arn. ex Munro are as follows:ash content 1.80%, SiO2 0.50%, cool water extractive 3.10%, hot water extractive 4.42%, benzene-alcohol extractive 2.65%, 1% NaOH extractive 17.24%, Klason lignin 16.67%, pentosan 25.43% and cellulose 50.55%; and the average fiber length is 3.79mm, fiber width 14.83μm, length-width ratio 255.56. D. hamiltonii Nees et Arn.ex Munro fiber length is longer, fiber length-width ratio and cellulose is higher and Klason lignin is lower, compared with Neosinocalamus affinis, Phyllostachys pubesdens, Piceo asperata, Pnus massoniana and Eucalyptus globulus Labill, it is easier to pulp than some other species of bamboo with its tearing strength property much better than that of the needle wood. Therefore, it is a good fiber material of bamboo for papermaking industry.更多还原
