复层矿脂包覆技术在滨海电厂钢结构关键部位的防护应用

Application of Multilayer Petrolatum Coated Anti-corrosion Technology to Key Parts of Steel Structure in a Coastal Power Plant

某滨海火力发电厂钢结构关键部位采用复层矿脂包覆技术进行腐蚀防护。通过中性盐雾试验和电化学试验研究了防蚀膏和防蚀带对对碳钢的防腐蚀效果,并介绍了该技术在滨海电厂钢结构关键部位的施工工艺和应用情况。盐雾试验和电化学试验结果表明,防蚀膏和防蚀带具有优良的耐盐雾和耐氯离子渗透性能。通过在滨海电厂钢结构关键部位的实际应用证明了其具有良好的防腐蚀性能。

Key parts of steel structure in a coastal power plant are coated with multilayer petrolatum coating. Salt spray test and electrochemical impedance spectroscopy （EIS） technology were used to study the anti-corrosion ability of anti-corrosion petrolatum grease and anti-corrosion tape. Applications of multilayer petrolatum coated anti-corrosion system were discussed, and the process of the technology was also introduced. The results of salt spray test and EIS showed that the anti-corrosion petrolatum grease and anti-corrosion tape had high obstructive capacity for H2O, O2 and Cl . The results of this project also illuminate that multilayer petrolatum coated anti-corrosion system is a reliable and advanced technology.
