摘要

本計畫之主要目標係探討台灣產量頗大，惟利用量不大的農業殘留物質，稻草，以化學機械法製造具適當性質紙漿之可行性。試驗包括稻草之液態蒸煮，繼以鍊漿；並評估紙漿性質。影響蒸煮結果之參數均以一含三變數二階層之階乘試驗設計分析以建立應變數與自變數間之關係。以10%總二氧化硫量及pH10.5之蒸煮液於150℃液態蒸煮22.5min，紙漿得率約66%。遊離度調整為200mL CSF之漿料具有良好之手抄紙強度。

The main objective of this study is to explore the feasibility of usingan abundant agricultural residue in Taiwan, rice straw, as raw material in chemi-mechanical pulping to produce pulps of adequate quality. The experimental work involved liquid-phase cooking of the straw materials, followed by refining and evaluation of pulp properties.
The parameters which affected the cooking outcomes were analyzed using a factorial experimental design consisting of 3 variables at 2 levels, and the correlations between the dependent and independent variables were thus established. Liquid phase cooking using 10% total sulfur dioxide and a liquor pH of 10.5 at 150℃ for 22.5 min gave a pulp with about 66% yield and when beaten to 200mL CSF, produced handsheets of adequate strength properties.
