2,4-二氨基嘧啶对冷轧钢在HCl溶液中的缓蚀作用
Corrosion Inhibition of 2,4-Diaminopyrimidine to Cold Rolled Steel in HCl Solution
摘 要
通过浸泡试验、电化学试验和扫描电子显微镜（SEM）观察研究了2,4-二氨基嘧啶（DAP）在1.0 mol/L HCl溶液中对冷轧钢的缓蚀作用。结果表明: DAP在HCl溶液中对冷轧钢具有良好的缓蚀作用; 缓蚀率随缓蚀剂含量的增大而增大，DAP浓度为10.0 mmol/L时缓蚀率最大，可达94.8%; DAP为混合型抑制型缓蚀剂，DAP在冷轧钢表面的吸附符合Langmuir吸附等温式，缓蚀率随温度的升高而下降。

Abstract
The corrosion inhibition of 2,4-diaminopyrimidine (DAP) to cold rolled steel (CRS) in 1.0 mol/L HCl solution was studied through immersion test, electrochemical test and scanning electron microscopy (SEM). The results show that DAP was a good inhibitor for CRS in HCl solution. The inhibition efficiency increased with the increase of the concentration of DAP, and the maximum inhibition efficiency could reach as high as 94.8% when the concentration of DAP was 10.0 mmol/L. DAP acted as a mixed-type inhibitor and the adsorption of DAP on the surface of cold rolled steel obeyed Langmuir adsorption isotherm. As the temperature rose, the inhibition efficiency decreased.
