研制了一种以咪唑啉缓蚀剂为主复配的XQ多功能缓蚀剂 ,对碳钢在盐酸酸洗液中有很好的缓蚀、抑雾、促洗等作用。采用恒电位以测量腐蚀极化曲线 ;用腐蚀失重法测量平均腐蚀速率 ;用酸雾测定装置测定抑雾率。结果表明 ,缓蚀率可达 99.6 % ,抑雾率达 85% ,促洗作用显著 ,且酸耗降低 11%以上 ,并探讨了其缓蚀机理 Developed a kind of XQ multifunctional corrosion inhibitor with imidazoline as the main compounding agent, which has good corrosion inhibition, fog suppression and wash-wash effect on hydrochloric acid pickling solution. Constant potentials were used to measure the corrosion polarization curve; the average corrosion rate was measured by corrosive weight loss method; and the anti-fogging rate was measured with the acid mist measuring device. The results showed that the inhibition rate was up to 99.6%, the anti-fogging rate was 85%, the salting-out effect was remarkable, and the acid consumption was reduced by more than 11%. The corrosion inhibition mechanism
