摘要

本研究主要在於探討速生闊葉樹材木片長度對硫酸鹽法及中性亞硫酸鹽半化學法製漿之影響，結果顯示闊葉樹木片長度對紙漿纖維長度僅有微小之破壞，木片長度由3.58公分降到0.33公分，纖維長度約下降10%。小木片用較低之藥量蒸煮可獲得較低之殘留木質素量，並維持良好紙漿收率，且紙漿性質不受影響。惟人工切片之紙漿強度略高於機器切片，其原因有待進一步之探討。本研究亦發現黑栲之木材比重高，製漿容易，紙漿性質良好，是一優良之紙漿用材。

Wood chips of Acacia mearnsii in four different sizes were prepared by chipper and hand. The chips were made between 0.33 cm and 3.58 cm in length (grain direction). It was found that when a chip is shorter, the proportion of its cut fibers in the resulting pulp would turn out to be larger. However, the average length of pulp fibers from the shortest chips (0.33 cm) was found to stay very high, or about 91 percent of that resulting from the longest chips (3.58 cm). Shorter chips of Acacia mearnsii significantly facilitated the delignification reactions in the kraft and neutral sulfite pulping. In addition, the properties in tensile and tear strengths of kraft and neutral sulfite pulps made from shorter chips are comparable to those from longer chips. Meanwhile, pulps from hand-made chips show slightly higher properties in both tear and tensile strenghts.
The results of this pulping experiment also show that Acacia mearnsii is a good raw material for kraft and neutral sulfite semichemical pulps.
