Abstract:

The stability of zinc ion in the circulating water isdisclosed.The effect of copolymer ZF322and the quality of circulating water on zinc ion isstudied at lab.The experiment result showsthat the stability of zinc ion getshigher with more ZF322and there iscritical value effect.The presence of Fe³⁺,Ca²⁺and alkalinity can decrease the stability of zinc ion.The stability isenhanced by phosphate with low concentration.pH value hasmore effect on the stability of zinc ion and haslesseffect after adding the chemical.

Key words: zinc ion, stability, circulating water

摘要：

研究了循环水中锌离子的稳定性，讨论了磺酸盐共聚物和水质因素对锌离子稳定性的影响。结果表明，随着磺酸盐共聚物ZF322浓度的增大，循环水中锌离子的稳定性增强;三价铁离子、钙离子浓度和碱度的增加都会降低锌离子的稳定性;正磷在低浓度时可增强其稳定性;pH值对锌离子稳定性影响很大，但加入药剂后影响比较小。
