采用静态阻垢法和旋转挂片法通过筛选得到了一种适宜中央空调循环冷却水处理的绿色复合型水处理剂.利用扫描电镜对形成的垢样进行形貌观察,采用电化学方法分析了复合药剂的缓蚀机理.结果表明:当PESA、PAAS、BTA、SDBS的复配质量比为8∶2∶5∶25时,复合药剂的阻垢缓蚀效果最佳,最佳加药量为80 mg/L,此时,复合药剂的阻垢率大于90％,对A3碳钢和T2紫铜的缓蚀率分别达到91.13％、88.61％.

Static scale inhibition method and rotary coupon tests were used to obtain a kind of green agent, which is suitable for central air conditioner circulating cooling water treatment. Scanning electron microscopy （SEM） was used to observe the morphology of the scale samples, and electrochemical method was used to analyze the corrosion inhibition mechanism of the compound agent. Results show that the best ratio of the compound （PESA, PAAS, BTA, SDBS） was 8 ： 2 ： 5 ： 25, and the optimal dosage was 80 mg/L. At this proportion, the scale inhibi...
