| 摘 要： | 对聚天冬氨酸与氧化淀粉复配物的阻垢性能进行了研究。结果表明复配物的最佳配比浓度为：聚天冬氨酸与氧化淀粉各自的浓度均为1mg/L；复配物的阻垢性能较单纯的聚天冬氨酸有一定的提高，适用于高钙、高pH、高温的水系统中，并可在其中长时间停留；复配物使碳酸钙的晶格生长受到抑制，晶粒尺寸变小。

| Abstract: | In this paper, the scale inhibition of combination of polyaspartic acid (PASP) and oxidized starch (OSIII) was discussed. The optimum dosage of the combination is: PASP 1 mg/L, and OSIII 1 mg/L. It can be used in water system with high calcium concentration and high pH value, and the significant scale inhibition can still be remained even staying in high temperature water system for long resident time. In addition, it can control the growth of crystal lattice of calcium carbonate. As a result, the dimension of grain is smaller. |
