【摘要】 本文对几种不同产地的实心和空心桉木的制浆造纸性能进行分析。就纤维形态而言 ,总体上实心材的纤维长度和宽度均大于空心材 ,而长宽比小于空心材。化学成分分析表明 ,实心材的木素含量较少 ,碳水化合物含量较高。实心材的高锰酸钾值较低 ,得率稍低。经过漂白和打浆后 ,不同产地原料间的差别更加明显更多还原

【Abstract】 The performances of pulping and papermaking of solid heartwood and false heartwood of Eucalyptus that growed in different areas were analysed and estimated. As fiber morphology concerned,in general, the fiber of solid heartwood was longer and wider than that of false heartwood,and the length to width radio was lower .The analysis of chemical component showed that the lignin content of solid material was lower, but the carbohydrate content of solid heartwood was higher.The KMnO 4 number of solid heartwood pulp was lower as the unscreened yield was a little lower.After bleaching and beating,the difference of their properties was more obvious.更多还原
