摘要
本文采用传统的一步法合成阻垢剂聚环氧琥珀酸(PESA),并用红外进行表征。电导率法评定PESA的阻垢性能较好。通过改变溶液温度、阻垢剂浓度测定溶液的电导率随时间的变化值,推断PESA影响碳酸钙结垢过程的原因:低温时晶格畸变起主要作用;高温时分散起主要作用,从动力学上影响碳酸钙结垢过程。温度发生变化,PESA影响碳酸钙结垢过程的控制过程发生改变。加晶种时,PESA表面吸附作用显著。PESA的阻垢效果不能用络合效应理论解释。
in this paper, traditional one--step method was adopted to synthetize PESA, the green-- acid inhibitor, which was characterized by infrared. It is better to determine sealing inhibitation of PESA through Conductivity law. Speculating the reason in the process of the scaling of calcium carbonate under the influence of PESA through determining variation on conductivity law in solution by changing temperature of solution and concentration of scaling inhibitor： when at low temperature, lattice distortion plays a major role; when at high temperature, scattering plays an important role, and influences process of calcium carbonate scaling from dynamics. When temperature is varying, the controlling process which PESA influences the procedure of calcium carbonate scaling is changing. When adding seeds, the effect of absorption on the surface of PESA is obvious. The effects of PESA＇s scaling of inhibitation could not be explained through the theory of complex effect.
