通过锌盐在阴极形成氢氧化锌沉淀膜抑制阴极反应而达到缓蚀。
Corrosion is inhibited by zine salt forming a protective film of zine hydroxide at the site of the cathodic reaction.
溶液的流动方向由上而下有利于沉淀物的沉降,减少沉淀物漂浮对阴极质量的影响。
The flowing direction of the solution from top to bottom is beneficial for the deposition of the deposit so as to reduce the influence of the floating of the deposit on the cathode quality.
