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。

Abstract:

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 maximum 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 sulphate scale

Key words: calcium sulfate, scale inhibitors, polymph?
