| 摘 要： | 用鼓泡法对六种聚天冬氨酸 (Polyasparticacid ,PASP)的阻碳酸钙垢性能进行了评价 ,考察了pH值、阻垢剂用量、温度、恒温时间等对阻垢性能的影响。研究发现 ,阻垢率随着聚天冬用量的增加而增大 ,其用量在 1 0mg/L时 ,已能获得较好的阻垢效果。另外 ,与聚丙烯酸 (PAA)和聚马来酸 (HPMA)的比较发现 ,聚天冬在高温水系统中作长时间停留 ,仍对碳酸钙垢有较强的抑制作用

| Abstract: | Function of poly-aspartic acid for inhibiting calcium carbonate scale was evaluated by air blowing in the laboratory. The result shows that calcium carbonate scale inhibition of poly-aspartic acid is enhanced with increase of the concentration of poly-aspartic acid and poly-aspartic acid can keep effective even at high temperature for a long time. |

| Keywords: | poly-aspartic acid scale inhibitor dynamic method |
