PAM对CaCO_3显微结构的影响

Effects of PAM on CaCO_3 Micro-structure

利用原子力显微镜(AFM)研究添加聚丙烯酰胺(PAM)后碳酸钙晶粒表面形貌的变化。观察实验所得图像发现加入PAM后碳酸钙晶体发生了较大的形貌变化。空白样品碳酸钙表面致密平整,而加入PAM的样品碳酸钙表面凸起和凹陷明显增多。结果表明,PAM对碳酸钙显微结构的影响与阻垢剂所具有的部分作用机理相似。

Atomic Force Microscopy （AFM） was used to study the effects of adding （PAM） to calcium carbonate. The pictures showed that calcium carbonate crystal morphology is affected by the addition of PAM. The surface of calcium carbonate is neat before Polyacrylamide is added, while the surface of calcium carbonate with PAM is uneven. The result reflects a number of ways in which PAM plays a role in the process as an inhibiting mechanism.
