咪唑啉类成膜缓蚀剂BW对金属表面沉积物或垢的去除研究

Study on the Removal of Scale on the Metal Surface by a Kind of Film-Growth Imidazoline Inhibitor BW

摘要: 通过高压釜试验、电厂应用试验和水滴试验、酸性CuSO4点滴试验，研究了一种可用于目前我国火力发电厂热力设备停用保护的咪唑啉类成膜缓蚀剂BW对金属表面沉积物或垢的去除性能。研究结果表明，BW在已锈蚀的碳钢试片表面和电厂热力设备金属表面形成耐蚀性较好的保护膜的同时，对锈蚀试片表面的腐蚀产物、热力设备金属表面的沉积物或垢有一定的清洗、去除作用。

Abstract: The property of removal of scale on the metal surface by a kind of film-growth imidazoline inhibitor BW fitting for lay-up protection of thermal equipments in domestic power plant at present was examined by the autoclave test in the laboratory and the application test in the power plants, and droping water and acidic CuSO4 test. Results showed that film could be formed with BW on the metal surface, and the rust on the metal surface and the scale on the thermal equipment surface could be removed by BW.
