| 摘 要： | 使用电化学方法对2种不同的醇溶型无机锌车间底漆进行了研究,结合浸泡以及盐雾的实验结果,发现2种车间底漆中锌含量对阴极保护时效有影响,但不是决定车间底漆防锈能力的唯一因素,锌含量与防锈颜料对于车间底漆的防锈性能有协同效果。其中,锌粉在早期提供阴极保护的作用,而防锈颜料在后期对基底提供防锈保护。对于锌粉含量相对较高的车间底漆,锌粉并不是从一开始就全部参加阴极保护作用,而是一部分具有激活潜力的锌粉在另一部分锌粉率先反应之后才由“未激活状态”转变为“激活状态”进而提供阴极保护的作用。

| Abstract: | The anticorrosive behavior of two kinds of alcohol-soluble inorganic zinc shop primers has been investigated by means of electrochemical measurements, immersion test and salt spray test. The results show that zinc content in shop primer can influence the period of cathodic protection, but it is not the only factor that decides the anti-rust ability of shop primer, and the anticorrosive pigment also plays an important role as well. For the shop primer with high zinc content, a part of zinc powders would be activated to provide cathodic protection after another part of zinc powders, which means that not all of zinc powders participate in cathodic protection in the very beginning. |
