Abstract

Dodecylamine, quinoline, allylthiourea, and thiourea, whose dipole moments were calculated by quantum chemistry and in gradient rise, were used to study the influence of magnetic field on inhibition effect through weight loss experiments, electrochemical measurements, and surface characterizations. Results confirmed that the inhibition efficiency can be improved to varying extents with the application of the magnetic field. In addition, maximum impedance increased three times more than that in controlled trial when the magnetic field increased to 12 mT. Furthermore, the inhibition efficiency of inhibitors with larger dipole moment will be affected more obviously, which was also positively related to the magnetic field strength. The mechanism of variation in polarizability of molecules was proposed to explain the effect of the magnetic field.

磁场对不同偶极矩梯度缓蚀剂缓蚀性能的影响

摘要

十二烷基胺，喹啉，烯丙基硫脲和硫脲的偶极矩通过量子化学计算并以梯度上升的形式被用于通过失重实验，电化学测量和表面表征研究磁场对抑制作用的影响。结果证实，通过施加磁场可以在不同程度上提高抑制效率。此外，当磁场增加到12 mT时，最大阻抗增加了三倍于对照试验。此外，偶极矩较大的抑制剂的抑制效率将受到更明显的影响，这与磁场强度也呈正相关。提出了分子极化率变化的机理来解释磁场的影响。
