Research Progress of Inhibitor to Prevent Materials in the Recirculating Seawater Cooling System from Corrosion

分析了海水冷却系统的设备、管道及其材质，重点分析了防止海水循环冷却系统腐蚀的非绿色缓蚀剂和绿色缓蚀剂的研究进展。研究结果表明：1) 在海水循环冷却系统中，添加缓蚀剂是既简单又经济有效的金属腐蚀防止方法；2) 目前海水中缓蚀剂的研究，还主要处于探索阶段，不够成熟和完善，应研究、开发和应用无毒、无公害、可生物降解和环境友好的绿色缓蚀剂。 The equipment, pipelines and their materials in the cycling seawater cooling system are analyzed, and the research progress of non-green and green inhibitor to prevent materials in the cycling seawater cooling system from corrosion is manly analyzed. The research results show that the re-search of the corrosion inhibitor in the seawater at present is mainly in the exploring stage, not enough mature and perfect, and the green inhibitor which is nontoxic, pollution-free, biodegradable and eco-friendly should be studied, developed and applied.
