【摘要】 本文报导了对水杉(Metasequoia glyptostroboides)、Ⅰ-69杨(Populus deltoidesCV.’Lux’.)、Ⅰ-72杨(P.x euramericana cv.’San Martino’)等速生材的化学组分,纤维形态以及制浆性能所作的分析和研究。在研究中,除常规分析外,还使用UV分光光度计测定了“酸溶木素”,用薄层色谱法测定了综纤维素的糖基组成,用电子显微镜观察、测定了Ⅰ-69杨、Ⅰ-72杨中的应拉木(tension wood)。此外,还采用烧碱一蒽醌法和硫酸盐法对制浆性能做了初步探索。试验结果表明:水杉、Ⅰ-69杨、Ⅰ-72杨是宜于制浆的优良的速生树种,可以考虑在造纸工业中使用。更多还原

【Abstract】 This paper deals with the chemical components, the fibre dimensions and the pulping properties of sixteen species of fast-growing wood, such as the fossil tree (Metaseqvoia glyptostroboids) poplar I-69 (populus. var. deltoides cv. ’Lux’), poplar 1-72 (P. X euramericana cv. ’San Martino’), etc. Besides conventional analyses, acid-soluble lignins have been determined by means of a UV spectrophotometer; conv positions of the sugar residues of holocellulose have been analysed by thin layer chromatography; tension wood existed in poplar 1-69 and poplar 1-72 has also been observed and measured by using electronmicroscope. In addition, preliminary investigations have been made on their pulping properties by soda-anthraguinone process and kraft process. Results indicate that the fossil tree, poplar 1-69 and poplar 1-72 are excellent fast-growing wood which merits consideration in its application to paper-making industry.更多还原
