摘要
采用静态阻垢法研究了9种有机磷酸盐和水溶性聚合物对硫酸钙的阻垢性能,并用扫描电镜(SEM)及粉末X射线衍射仪(XRD)对垢样进行微观分析。结果表明,几种药剂对硫酸钙均有一定的抑制作用,且呈现出明显的槛值效应,在低浓度时,HDTMP的抑制效率最大,在10 mg/L时对硫酸钙的阻垢率达到67%,几种阻垢剂对硫酸钙垢的晶型和形貌都有较大的影响。
Static scale inhibition methods have been used for investigating the scale inhibition effect of 9 kinds of organo-phosphonate and water-soluble polymers on calcium sulfate. The scaled samples are micro-analyzed with electron microscopy （SEM） and X-ray diffraction （XRD）. The results show that these chemical agents have certain inhibition effect on calcium sulfate and significant threshold value effect. When the concentration is low, the maxi- mum inhibitory efficiency of HDTMP exists. The scale inhibitory rate on calcium sulfate could reach 67% when the concentration is 10 mg/L. These scale inhibitors have great effect on the polymph and morphology of calcium sul- phate scale.
