| 摘 要： | 本文对麦草中性亚钠蒸煮过程中纸浆得率和木素含量随蒸煮亚钠用量、蒸煮温度和时间及蒸煮液亚钠浓度变化的定量关系,用计算机作了辅助研究,得到7个数学模型。研究表明,对这一过程影响最大的是蒸煮液亚钠浓度变化,其次是蒸煮温度和初始亚钠用量,延长蒸煮时间的作用较小。数学模型亦定量描述了这些因素的协同影响作用。

| Abstract: | The quantitative relationships of pulp yield or residual lignin contents with four variables, e.g.cooking temperature and time, and initial Na_2SO_3 charge as well as Na_2SO_3 concentration in the cooking liquor during neutral sodium sulfite pulping of wheat straw were studied on a laboratory scale.Scven mathematical models that each contained five variables were developed with a micro computer,It revealed that Na_2SO_3 concentration in the cooking liquor effected the pulping processes most seriously.Second one of four variables was cooking temperature.And prolonging the at-temperature period to further remove the residural lignin was not required because of its little function in the model.The models also expressed the synergistic effects of variables on the pulping processes quantitatively. |
