摘要
本文在清除吸附和固定其它影响因素的条件下,研究了孔隙结构对部分水解聚丙烯酰胺捕集滞留量的影响,指出与捕集滞留量密切相关的孔隙结构特征参数为相对分选系数、均质系数、结构系数以及综合参数。文中提出的孔隙半径均值与孔喉半径中值之比以及易捕集孔隙喉道百分数能够更好地反映孔隙结构对捕集滞留量的影响。
In this paper effect of pore structure on polymer retention is discussed by eliminaating the effect of'adsorption.It is shown that characteristic parame- ters of the pore structure closely related to polymer retention by entrapment are relative sorting coefficient D,uniformity coefficient a,configuration coef- ficient φ and comprehensive parameter J.The ratio of averaged pore radius to the mean value of throat radius and percentage of pore and throat,which has a more significant effect on the entrapment of polymers as suggested in this paper,may give a batter description of the effect of pore structure on polymer retention.
