查询词典 alkali cellulose

The alkali dosage depends mainly on the constituents and property of material and the quality requirements for pulp: more alkali dosage will speed up cooking process, reduce the hardness of pulp and improve the bleachability of pulp; but excessive alkali dosage will lower the pulp yield and physical intensity, while too less alkali dosage will result in harder and darker pulp, uneasy to bleach, too much screenings, and even extending cooking time cannot guarantee the reaction of delignification.

用碱量主要取决于原料的组成和性质及对纸浆的质量要求：加用碱量有利于加快蒸煮速度降低纸浆硬度和提高纸浆的可漂性：但过高却会降低纸浆得率和物理强度，如过低时，成浆较硬而色暗，不易漂白而且筛渣多即使延长蒸煮时间也难以保证脱木素反应进行。
