摘要
根据曹娥江大闸的环境特点,对不同厂家的7种富锌涂料进行了近2年的浪溅区、潮差区和大气区的室外暴露试验和近10500 h的盐雾试验、盐水周期性浸泡试验和盐水浸泡试验的室内试验研究,得出几点结论:不同厂家的富锌涂料由于配方不同可能存在性能差异,有时差异程度可能很大;高锌粉含量的有机富锌涂料防腐蚀性能最优,低锌粉含量的环氧富锌涂料防腐蚀性能最差;设计部门或工程业主在设计富锌涂料做底涂时最好委托有关部门做前期防腐蚀试验论证。
According to the environment in Cao′e River floodgate,seven zinc-rich coatings were selected as test samples to investigate their anticorrosion properties by tests of outdoor exposure in splash zone,tideland and atmospheric zone for about two years and outdoor tests such as salt fog test,cycle salt solution test and salt solution test for about 10500 h.Different zinc-rich coatings from different factories showed different properties.The anticorrosion properties of high zinc content coatings were better than...
