摘　　要：介绍了混合清洗液的除垢和钝化试验研究结果,由中国科学院金属腐蚀 与防护研究所等单位用交流阻抗技术、电子扫描电镜、金相显微镜及毒性试验等检查评定的 结论。同时就混合清洗液除垢钝化机理、除垢钝化、电化学行为、氢脆膜的耐蚀性等方面的 试验与结果进行了介绍。该研究成果在大型锅炉上的应用获得了成功,除垢完全,钝化效果好,机组启动后,水汽品质很快达标。The mixed cleaning solution for scale removing and passivating was examined and reviewedby Institute of Corrosion and Protection of Metals of the Chinese Academy of Sciences with alternatecurrent impedance technology,eleotronic scanning microscope,photoelectric metallographicmicroscopeand toxicity test,and gained satisfactory results.The test with the mixed solution was success-ful in large operating boilers.Scale was cleaned thoroughly,passivating film was formed better,andquality of water and steam was soon qualified after the unit start-up.
