摘　　要：开发了一种酰胺类无磷缓蚀剂,在中碱度中硬度水质中进行了缓蚀应用研究。选用A3碳钢作为测试对象,采用旋转挂片失重法和电化学阻抗法对酰胺类无磷缓蚀剂的缓蚀性能进行研究。测试结果表明,该酰胺类无磷缓蚀剂在中碱度中硬度的循环水水质下具有良好的缓蚀性能,能够有效地满足循环水系统的金属缓蚀需求。A kind of amide derivative non-phosphorus corrosion inhibitor has been synthesized. Its application to corrosion inhibition in water with moderate alkalinity and moderate hardness is studied. Using carbon steel A3 as de- tection target, the corrosion inhibiting capacity of amide derivative non-phosphorus corrosion inhibitor by rotary coupon weight-loss method and electrochemical impedance method is studied. The results indicate that the amide derivative non-phosphorus corrosion inhibitor has good corrosion inhibiting capacity in circulating water with moder- ate alkalinity and moderately hardness, being able to effectively meet the metal corrosion inhibition requirements for circulating water systems.
