摘要

针对火电厂循环冷却水水质研究了聚天冬氨酸(PASP)的阻垢性能及对凝汽器铜材质(HSn-70A铜)的缓蚀性能。试验结果表明

PASP阻垢效果优良

但单一PASP的缓蚀用量较大。为此

对PASP的复配方案进行了研究。筛选出的最佳复配配方为10 mg/L PASP+0.5 mg/L BTA+20 mg/L钼酸钠+10 mg/L葡萄糖酸钠。采用该配方后HSn-70A铜的腐蚀率仅为0.000 4 mm/a

缓蚀率达到了99.17%。

Abstract

Directing against the water quality of circulatory cooling water used in the thermal power plants

the scale-retarding performance and the corrosion-inhibiting performance for copper materials(HSn-70A) in the condenser using polyaspartic(PASP) acid have been studied.The test reuslts show that the PASP acid has good effect on scale-retardation but used amount of single PASP acid for corrosion inhibition being large.For this reason

a combination of four medicals has been studied to find out the optimal proportioning ratio and the synergistic effect.The optimal proportioning ratio of combination from four medicals is as follows:10 mg/L PASP acid + 0.5 mg/L BTA + 20 mg/L sodium molybdate+10 mg/L sodium gluconate.After application

the corrsion rate of HSn-70A copper is only 0.000 4 mm/a

corrosion inhibiting rate reaches 99.17%.
