摘要： 用JF99A粉体接触角测量仪测定了水溶性阳离子聚合物NCP溶液和部分水解聚丙烯酰胺HPAM溶液在粉体钙质蒙脱土上的润湿性. 实验结果表明NCP溶液在0~1 g/L浓度范围内蒙脱土表面的润湿接触角比水在蒙脱土表面的润湿接触角小，并且比浓度相当的HPAM溶液在蒙脱土表面的润湿接触角要小得多；相同浓度NCP和HPAM溶液中达到吸附平衡的蒙脱土干燥过筛处理后的样品对水的润湿接触角也是前者小于后者，其差别比各自溶液在蒙脱土上的润湿性的差别更大，即经NCP处理后的蒙脱土对水的润湿性明显变好，而经HPAM处理后的蒙脱土对水的润湿性变差.

Abstract: The wetting ability of the solution of water-soluble cationic polymer NCP and the solution of HPAM (partial hydrolytic polyacrylamide) on the surface of Ca-montmorillonite was determined by a JF99A contact angle calcimetre. The former has a smaller contact angle than the latter. The results of relative wetting angle show that NCP has better hygroscopicity. On the other hand, when montmorillonite was saturately adsorbed by NCP and HPAM solutions and was disposed by filtrating, washing, drying and sieving, the results of contact angle in water solution show that the NCP–MT has better hygroscopicity than HPAM–MT.
