摘要
国内南方某核电站在工程建设阶段海水过滤系统粗格栅防污涂层大面积脱落失效,本文对失效原因进行了分析,并采用挂片试验法分析新选用防污涂层体系在相同海水环境下的适用性。试验结果表明对比样板表面的防污漆A/F Seaquantum Ultra对海生物有良好的杀消和防附着作用,其防污性能要好于CTN3954。同时,Intrpime539和CTN3948两种底漆与不锈钢基材均有良好的附着力。
Anti fouling paint on coarse grid of sea water filtration system peeled off in the nuclear power station in southern China. The cause of failure was analyzed in this article. The application of the method of hanging test was used to analyze the applicability of the new coating system in the same seawater environment. The results show that A/F Seaquantum Ultra has a better anti fouling effect than CTN3954. The primer coatings of Intrpime539 and CTN3948 have good adhesion with stainless steel.
