采用旋转搅拌装置和GC-MS法研究了pH值对钙离子存在下树脂沉积的影响.发现pH值的降低会导致树脂的沉积,pH7.0是转折点.将这些树脂分离成结合树脂和游离树脂后进行GC-MS分析,结果表明,钙皂和游离树脂对沉积物的形成有共同的贡献,结合树脂在低pH值和高温下转变为游离树脂.酸性组分对钙皂的形成起重要作用,而脂肪酸皂在低pH值下更稳定.

The effects of pH value on resin deposition with the presence of CaTM were studied by usingthe device of "Rotating-mixer" and the method of GC-MS analysis. It is found that the decrease of pHvalue results in resin deposition and pH7.0 is the turning point. The deposits were analyzed by GC-MSafter being separated into combined resins and free resins. Experimental results show that calciumsoaps and free resins contribute together to deposits formation. The combined resins would change intofree resins at low pH and high temperature. Acidic components play an important role in soapsformation and the soaps of fatty acids are more stable at low pH value.
