为了解决目前循环冷却水系统中结垢和多金属的腐蚀问题以及传统化学加药处理法中存在普遍含磷、加药复杂等问题,通过系列筛选和优化试验得到了一种具有优良阻垢效果,并同时对铜、铁和铝3种材质具有良好缓蚀作用的复合绿色水处理剂。采用静态阻垢法、旋转挂片法、电化学测试(极化曲线)、表面分析技术对其阻垢缓蚀性能及机理进行了研究。结果表明:复合药剂的阻垢率高达96.2%,对Q235碳钢、T2紫铜和6063铝合金的缓蚀率分别达到94.0%、95.5%和93.4%,是一种性能优良的阻垢缓蚀剂;它通过吸附在CaCO3晶面的活性生长点,使晶格发生扭曲、分散而不能形成垢,达到阻垢效果;电化学测试结果显示该复合绿色水处理...

In order to overcome the scaling formation in circulating cooling system,polymetallic corrosion issue and the drawbacks of traditional chemical feeding treatment such as containing phosphorus and complicated process,an environmentally friendly multi - component inhibitor for circulating cooling water system was developed by systematically selecting and optimizing experiments,which possessed good corrosion inhibition effect on Cu, Fe and Al materials. The calcium carbonate precipitation method, rotary coupon test, polarization curve measurement and surface analysis technology were used to inves...
