Performance Evaluation of Friction-Reducing and Wear-Resistant Heavy-Duty Anticorrosive Coating for Thermal Pipeline

热力管线的防腐和减阻在供热领域具有重要意义。采用改性环氧树脂、氟聚合物、防腐颜填料、胺固化剂等制备了一种新型的热力管道用减阻耐磨重防腐涂料。通过差示扫描量热仪、盐雾试验、高温水煮、电化学阻抗分析、表面接触角分析、表面粗糙度分析对涂层性能进行分析,并通过实际工程项目对涂层的减阻性能进行评估。所制备的热力管道减阻耐磨涂料,拥有良好的防腐性能、机械强度、涂层表面光滑、表面能低、疏水性优良,可显著降低输送过程中的水与管道的摩擦阻力,提高了供热和换热效率(平均减阻节能达到了30%以上),具有较好的经济效益。

Anticorrosion and friction-reducing of thermal pipelines are of great significance in the field of heating.A new type of friction-reducing,wear-resistant and heavy-duty anticorrosive coating for thermal pipeline was prepared by using modified epoxy resin,fluoropolymer,anticorrosive pigment and filler,amine curing agent and so on.The performance of the coating was analyzed by differential scanning calorimeter,salt spray test,high temperature boiling,electrochemical impedance analysis,surface contact angle analysis,surface roughness analysis and the friction reduction performance of the coating was evaluated through actual engineering projects.The prepared frictionreducing and wear-resistant coating has good anticorrosive performance,mechanical strength,smooth coating surface,low surface energy and excellent hydrophobicity.It can significantly reduce the friction resistance between water and pipeline during transportation,improve the heating and heat transfer efficiency(more than 30%in average)and show significant economic benefits.
