研究氧化物协同留硅蒸煮工艺,并运用均匀设计和偏最小二次回归分析方法对蒸煮工艺条件进行了优化,得到最佳工艺条件为:氢氧化钠13%、氧化铝0.41%、氧化镁0.51%、氧化钙3.2%。在该条件下纸浆得率48.64%,高锰酸钾值10.52,纸浆的二氧化硅含量3.62%;黑液的二氧化硅含量1.37g·L-1,黑液pH11.83。 Study on the synergistic Si-Si oxide cooking process, and the uniform design and partial least-squares regression analysis were used to optimize the cooking conditions. The optimum conditions were as follows: sodium hydroxide 13%, alumina 0.41%, magnesia 0.51 %, Calcium oxide 3.2%. Under these conditions, the yield of paper pulp was 48.64%, the potassium permanganate value was 10.52, the content of silica in pulp was 3.62%, the silica content of black liquor was 1.37 g · L-1, and the black liquor pH was 11.83.
