海上钢结构防腐蚀措施的研究

Study on Anticorrosion Measures for Offshore Steel Structure

针对海上钢结构严重腐蚀环境,分析了影响其腐蚀的主要因素,比较分析了钢结构常用的几种腐蚀防护方法。由于电弧喷涂复合涂层具有20 a以上的长效防腐寿命和涂层结合强度高、免维护等特点,因而成为海上钢结构防腐蚀的优选技术方案。还列举了国内外钢结构热喷涂防腐措施的应用实例及相关标准,对加强海上钢结构长效防腐的立法和推广应用提出了看法。

In this paper, the main factors affecting the offshore steel structure corrosion are analyzed according to its severe corrosion environment, and the common anticorrosion methods for the offshore steel structure are compared with each other. The electric arc spray coating has a long anticorrosive life of more than 20 years and is characterized by high binding strength and being service-free, so the spray coating method has become the optimal anticorrosion scheme for the offshore steel structure. The domestic and foreign cases for applying the anticorrosion technique and relevant standards are listed, and the opinions on the strenthering of legislation and the extension and application of longterm anticorrosion measures for offshore steel structure are expressed.
