水泥基渗透结晶型防水涂料中的活性离子可以与钙离子形成一种溶于水的不稳定络合物,通过络合-取代反应生成不溶于水的结晶体沉淀来达到使水泥混凝土结构防水的目的.采用分光光度法对该不稳定络合物的稳定常数进行了测定.
An unstable water-soluble complex compound can be formed by the reaction between active ion of permeable crystalline coating and calcium ion,a great quantity of needle water-fast crystals are produced by complexation-substitution reaction,which can prevent the pores and cracks of concrete and improve the impermeability of concrete.In this paper,the stability constant of unstable complex compound is measured by spectrophotometry.
