通过筛选和优化得到最佳配方的复合型水处理剂,该复合配方的组成为水解聚马来酸16 mg/L+表面活性剂1.5 mg/L+月桂酰基肌氨酸钠75 mg/L+唑类2.0 mg/L。采用静态阻垢法、旋转挂片法和极化曲线法对复合型水处理剂的阻垢缓蚀性能进行了研究,采用扫描电镜对腐蚀试片和垢样的形貌进行了观察。结果表明,复合药剂的阻垢率高达95.70%,对A3碳钢和T2紫铜的缓蚀率分别达到95.58%和93.25%,是一种性能优良的阻垢缓蚀剂。复合药剂通过吸附在CaCO3晶面的活性生长点,使晶格发生扭曲,以达到阻垢效果,复合药剂对A3碳钢是一种抑制阳极极化为主的混合型缓蚀剂;对T2紫铜是一种抑制阳极极化的阳极型缓蚀剂。

In order to solve the problems of scaling and corrosion of copper and iron in cooling water system for central air conditioner, an optimal compound water treatment agent was developed by screening assay. The compound agent consists of HPMA 16 mg/L+ Surfactant 1.5 mg/L+SLS 75 mg/L+Azole 2.0 mg/L. The performance of corrosion- and scaling- inhibition of the compound agent was characterized by immersion test, rotary coupon test, polarization curve measurement and SEM. Results show that, the compound water treatment agent is a kind of high performa...
