摘要
在工业生产中的水处理环节,常面临钙垢沉积问题。钙垢主要由碳酸钙构成,含方解石和文石。垢层会降低传热效率,增加能耗,易致设备堵塞和腐蚀,亟需开发高效环保阻垢剂解决积垢问题。基于此,通过分子动力学模拟方法,深入探究IA-SAS-HEMA共聚物与钙垢晶体(方解石和文石)之间的相互作用机理,采用分子动力学模拟技术,构建了IA-SAS-HEMA共聚物与方解石(104)及文石(122)晶面的复合物模型。模拟结果表明,IA-SAS-HEMA与方解石(104)晶面结合能力更强,阻垢效果更佳。研究结果为工业循环水系统中阻垢剂的开发提供了理论支撑。
In the water treatment process of industrial production,there is often a problem of calcium scale deposition.Calcium scale is mainly composed of calcium carbonate,containing calcite and aragonite.The scale layer will reduce heat transfer efficiency,increase energy consumption,and easily cause equipment blockage and corrosion.It is urgent to develop efficient and environmentally friendly scale inhibitors to solve the problem of scale accumulation.Based on this,the interaction mechanism between IA-SAS-HEMA copolymer and calcium scale crystals(calcite and aragonite)was deeply explored through molecular dynamics simulation method.Using molecular dynamics simulation technology,a composite model of IA-SAS-HEMA copolymer with calcite(104)and aragonite(122)crystal faces was constructed.The simulation results show that IA-SAS-HEMA has stronger binding ability with calcite(104)crystal plane and better scale inhibition effect.The research results provide theoretical support for the development of scale inhibitors in industrial circulating water systems.
