摘要
以醋酸环境下金属部件的腐蚀失效案例为导向,总结了金属材料在醋酸环境下的腐蚀机理、影响因素(如醋酸温度、浓度、杂质等)及防护措施,旨在为醋酸环境用金属材料的选择以及制定合理的防腐方案提供一定指导。
Acetic acid is an important raw material and plays an important role in the modern chemical industry.However,acetic acid is highly corrosive,which can easily cause corrosion of metallic components,threatening the service safety of equipment.In order to better understanding and preventing the corrosion induced by acetic acid,this paper summarizes the mechanisms,influencing factors(temperature,acetic acid concentration and impurities)and protection measures for corrosion of metals in acetic acid,on the basis of practical corrosion failure cases.It is expected to provide some guidance for selecting proper materials and taking effective measures to protect components serving in acetic acid environments from corrosion.
