摘要
通过分析海上平台保护涂层标准和相关技术文件,对海上平台的涂层系统、所涉及涂料产品、涂层系统认可试验进行详细阐述,以便于平台涂装方案的设计和涂料产品的开发和认证。采用抽丝剥茧逐步推进的方法,对标准、涂层体系、涂料产品和性能要求进行逐一分析解读,得出了不同腐蚀环境的涂层系统和涂层结构。依据底、中、面涂层结构,把平台常用的防腐涂料进行了归类,并给出了不同腐蚀环境涂层系统的性能要求和评测方法。海上平台涂层体系的设计,可以依据NORSOK M501和NACE SP 0108,二者可以相互补益。海上平台涂层体系的认可按NORSOK M501进行,采用ISO20340的涂层合格性试验,包括循环老化试验、海水浸泡试验和抗阴极剥离试验。建立海上平台防腐涂料体系,需要开发的品种有富锌涂料、环氧防锈漆、环氧云铁、环氧玻璃鳞片漆、低表面处理环氧涂料、厚浆性环氧漆、环氧砂浆、无溶剂环氧漆、酚醛环氧漆、聚氨酯面漆、工程硅氧烷等。
The work aims to facilitate design of platform coating scheme as well as development and certification of coating products by analyzing standards and relevant technical documents of protective coatings for offshore platform, and expounding approval test of coating systems. Requirements of standards, coating systems, coating products and property were analyzed and interpreted one by one by making a painstaking investigation. Coating systems and coating structures in different corrosion environments were obtained. Anti-corrosive coatings, which were commonly applied to the platform, were classified based upon base, interlayer and surface coating structures. Performance requirements and test methods of the coating systems in different corrosion environment were provided. The coating systems for offshore platform could be designed according to NORSOK M501 and NACE SP 0108 which complemented each other. The coating systems for offshore platform should be approved according to NORSOK M501 which employed test method of ISO20340, including cyclic aging test, seawater immersion test and cathodic abruption test. In order to build coating systems for offshore platform, such varieties as zinc rich paint, epoxy antirust paint, epoxy micaceous iron, glass flake epoxy paint, surface tolerant coating, thick-build epoxy paint, solvent-free epoxy paint, novalac epoxy paint, polyurethane paint and polysiloxane paint should be developed.
