This study elucidates the effect of zinc (Zn), which is an anticorrosive water additive, on the formation of silica scales from cooling water. In these experiments, the silica scales were analyzed by EPMA, and the results indicate that Zn is sorbed into the silica scales during formation. Measurements of the solubility of Zn(OH)(2) at various concentrations of silicic acid demonstrate that Zn is present as a silicato complex of Zn (SCZ) in cooling water. From adsorption experiments of the SCZ on silica and alumina, which are major components of the silica scales, it can be concluded that the SCZ accelerates the formation of silica scales from cooling water.
本研究阐明了锌（Zn）作为一种防腐水添加剂对冷却水形成硅垢的影响。在这些实验中，通过 EPMA 分析硅垢，结果表明 Zn 在形成过程中被吸附到硅垢中。测量不同浓度硅酸下 Zn(OH)(2)的溶解度表明，Zn 以 Zn（SCZ）硅酸配合物的形式存在于冷却水中。通过 SCZ 在主要成分是硅垢的二氧化硅和氧化铝上的吸附实验，可以得出结论，SCZ 加速了冷却水中硅垢的形成。
