摘　　要：从化学热力学角度和沉淀转化角度,理论上分析了碳酸钠、氢氧化钠分别与硫酸钙发生化学反应的可能性和反应进行的限度。并结合动力学规律,提出影响化学反应的条件,通过实验进行检验。最后提出,在实际工作中,达到良好清洗目的可采取的措施。The paper analyzes the possibilities and limits of chemical reaction between sodium carbonate,sodium hydroxide with calcium sulfate respectively,based on the theory of chemical thermodynamics and precipitation transformation. And combined with kinetics law,the corresponding chemical reaction conditions are proposed,and tested by experiment. Finally,the decent measures are also proposed.
