摘要

研究了纯纤维素、丝光纤维素和经稀硝酸处理的纤维素的絮凝作用。描述了高分子絮凝剂在纤维素上的吸附，并对结果进行了解释。酸处理的吸附和絮凝作用最大。研究了浓缩纤维素悬浮液的沉降行为，以确定纤维素颗粒的“标称半径”和相关参数。

The flocculation of cellulose powders with polymer flocculants

The flocculation of pure cellulose, of mercerized cellulose and of cellulose treated with dilute nitric acid has been studied. The adsorption of polymer flocculants on the cellulose is described and results interpreted. Acid pretreatment caused maximum adsorption and flocculation.

The sedimentation behaviour of concentrated cellulose suspensions has been investigated for the determination of the “nominal radius” of cellulose particles and of related parameters.
