分析了开发利用海水资源的必要性,论述了海水对碳钢的腐蚀、腐蚀机理及腐蚀的控制方法并探讨了缓蚀剂的缓蚀机理。从由单纯开发高效缓蚀剂到开发环境友好型高效缓蚀剂的转变,展望了未来缓蚀剂的开发研究前景。 The necessity of exploitation and utilization of seawater resources was analyzed. The corrosion, corrosion mechanism and corrosion control of seawater on carbon steel were discussed. The corrosion inhibition mechanism of corrosion inhibitor was also discussed. From the simple development of efficient corrosion inhibitors to the development of environmentally friendly and efficient corrosion inhibitors, the prospect of future development of corrosion inhibitors is prospected.
