兰桉制浆性能的研究

速生材兰桉在云南长势最好。从萌发力、纤维形态、化学成分等方面分析，认为１０ａ左右轮伐最为合适。运用硫酸盐法及ＣＥ０ＨＰ四段漂白可制得白度高达８６％（ＳＢＤ）以上的兰桉漂白浆。试验表明：兰桉木片易蒸煮、易漂白，化学药品耗量较低，且兰桉浆具有较好的强度，适宜于抄造多种文化用纸和制人造纤维浆粕。兰桉是一种良好的制浆原料。

The Pulping Characteristics of Eucalyptus Globulue Labill

In Yunnan,the fast-growing wood Eucalyptus globulus labill is growingbest,as analyzing from sprouding power,fiber form,chemical composition,etc. It isconsidered about ten years of tree age is suitest to fell.Cooking with sulfate process,andbleaching using the sequence of CE_0HP, the pulp brightness of greater than 86%(SBD)is obtained.Experimental results shown that Eucalyptus globulus labill easy cooking,thepulps easy bleaching,lower consumption of chemicals,in addition to,the pulp havehigher strength properties,therefore,it is suited to produce kinds of culture printing pa-per and rayon pulp.in short,Eucalyptus globtilus labill is a good pulping material.
