摘　　要：海洋石油工程股份有限公司制造场地分别位于天津、青岛和珠海,其中青岛场地夏季经常出现相对湿度超过85%对涂装不利的极端天气。在此环境下,基材表面的潮湿现象,极大影响施工效率并影响交付工期。该文对比环氧富锌+环氧云铁+聚氨酯、环氧铝粉漆体系、环氧玻璃鳞片体系等三个涂层体系在潮湿基材以及经过Sa2.5除锈的基材涂装后防腐性能的影响。通过对防腐体系的附着力、耐盐雾、冷凝试验等测试,得出结论,在涂膜外观无缺陷的情况下,潮湿基材表面涂装对三个涂层体系防腐性能有不利影响,但仍能满足配套涂层体系的防腐要求。The manufacturing sites of Offshore Oil Engineering Co.,Ltd.are located in Tianjin,Qingdao and Zhuhai,among which the Qingdao site often experiences extreme weather conditions with relative humidity exceeding 85%in summer,which is detrimental to painting.In this environment,the moisture on the surface of the substrate greatly affects the construction efficiency and delivery schedule.This article compares the anti-corrosion performance of three coating systems,including epoxy zinc-rich+epoxy micaceous iron+polyurethane,epoxy aluminum powder paint system,and epoxy glass flake system,on wet substrates and substrates after Sa2.5 rust removal.Through tests such as adhesion of films,salt spray resistance,and condensation tests of the anti-corrosion system,it is concluded that,under the condition of no defects in the appearance of the coating film,coating the surface of the wet substrate has a detrimental effect on the anti-corrosion performance of the three coating systems,but it can still meet the anti-corrosion requirements of the supporting coating system.
