水处理药剂阻CaCO_3垢性能与循环水中[Ca^(2+)和[HCO_3^-]的关系

RELATIONSHIP BETWEEN THE PERFORMANCE OF ANTISCALING AGENTS AND DIFFERENT CONCENTRATIONS OF Ca^(2+) and HCO_3^- IN COOLING WATER

考察了水处理药剂在不同[Ca2+]、[HCO]水质条件下阻CaCO3垢的一些规律。结果表明，同一种药剂阻CaCO3垢性能不仅受水中[Ca2+]+［HCO］总值的影响，还与[Ca2+]／[HCOF]有关。采用透射电镜对不同试验条件下垢样观察分析，发现水处理剂对不同条件下生成的CSCO3垢样表现出不同的扭曲作用，从而影响水处理剂的阻CaCO3垢性能。

The inhibition of Ca-scale formation by antiscaling agents was studied through a series of aqueous solutions with different concentrations of Ca2+ and HCO All samples of scale obtained were influenced by both said concentrations. The effects of antiscaling agents on CaCO3 scales formed were obviously different, consequently, the performance of antiscaling agents appeared to be different.
