高硅铸铁阳极
- 产品详情
高硅铸铁阳极是外加电流阴极保护系统中的关键掩埋组件，作为辅助阳极为陆地与海洋建筑物提供防腐蚀保护。针对外加电流高硅铸铁阳极的化学性能，相关标准已有详尽规范；目前我司已完成技术升级换代，推出的数字模块化产品性能稳定，可显著提升设备的抗腐蚀性能。
高硅铸铁具备优异的导电性能，当阳极电流通过时，其表面会发生氧化反应，生成一层薄的二氧化硅保护膜。该保护膜具有高电阻率和强化学稳定性，能使阳极在酸性环境中处于钝化状态，从而大幅降低阳极的溶解速率。
此外，通过添加铬元素改良的高硅铸铁，可让二氧化硅保护膜具备抵抗碱腐蚀和氯离子侵蚀的能力。这一特性使含铬高硅铸铁阳极能够适应含氯化物的复杂环境，进而广泛应用于各类土壤或水体条件下的防腐工程。
