摘　　要：采用新型纳米抗垢涂料是解决城市原生污水冷热源系统污垢的有效措施之一.通过工程现场的实验,对XK-368钛纳米聚合物换热器专用涂料涂层管在污水冷热源系统中抗垢性能进行了测试.结果表明,在工程应用范围内,相同工作条件下,系统污垢达到稳定时纳米涂层管换热热阻约为普通无缝钢管的50%;结垢时间常数约为普通无缝钢管的2.5倍.表现出良好的抗垢性能.One efficient way to solve fouling in urban sewage cooling and heating systems is the use of a new nano-particle containing paint.On site experiments have determined the anti-fouling properties of coated pipes.The coating used was XK-368 titanium nano-particle polymeric paint for heat exchangers.These experiments are finished in range of engineering application.The stable thermal resistance of the coated pipes was found to be 50% of that seen for normal steel pipe in the same application.The time constant of fouling equation was 2.5 times for the coated pipe.It is demonstrated that the anti-fouling performance of the nano-particle containing coating was very good.
