摘　　要：研究进口阻垢合金微观组织及阻垢机理对于解决污垢导致的能源浪费及设备损坏等问题有重要意义。研究了一种进口阻垢合金的成分、微观组织、阻垢性能及机理。研究表明,阻垢合金的主要成分为铜、锌、镍,含有微量的锡、铅、铁、锰、铬、铌、硅;合金的阻垢率在50%到70%之间,改变铜锌合金数量、间距和改变循环水的流量都会影响铜锌合金的防垢阻垢性能。合金在水处理过程中,以锌离子为主的阳离子由铜锌合金的微小原电池反应析出,使得碳酸钙晶体由方解石向文石与球霰石转变。亚稳态的水垢能够更容易被水冲走,从而减少水垢,实现阻垢目标。It is of great significance to study the microstructure and scale inhibition mechanism of imported scale-inhibiting alloys for solving the problems of energy waste and equipment damage caused by fouling.The composition,microstructure,scale inhibition performance and mechanism of an imported scale-inhibiting alloy were studied.The results showed that the main components of the scale inhibition alloy are copper,zinc and nickel,and contain trace amounts of Tin,lead,iron,manganese,chromium,niobium and silicon.The scale inhibition rate of the alloy is between 50%and 70%.Changing the number and spacing of the copper and zinc alloy and changing the flow rate of circulating water will affect the scale inhibition performance of the copper and zinc alloy.During the water treatment process of the alloy,cations mainly composed of zinc ions are precipitated by the reaction of the tiny primary cell of the copper-zinc alloy,so that the calcium carbonate crystals are transformed from calcite to aragonite and vaterite.Metastable scale can be more easily washed away by water,thereby reducing scale and achieving the goal of scale inhibition.
