头孢唑类缓蚀剂及其机理研究

Studies on Cefazolin Salt Inhibitor and Its Inhibiting Mechanism

在研究锌锰干电池缓蚀剂的基础上 ,筛选了一种头孢唑类的新型缓蚀剂 .通过极化曲线的测试 ,得到这种缓蚀剂具有良好的缓蚀效果 ,并用交流阻抗对其机理进行了较深入的研究 .

A new type of inhibitor was selected on the basis of the study of cefazolin salt inhibitor in zinc-manganese battery. The polarization curves of the inhibitor were measured. The experimental results show that this new inhibitor has an efficient inhibiting effect, which in creases with its concentr-ation. The inhibiting mechanism was studied through the impedance curve and cycle volt-ampere curve. The results show that the inhibiting effect is mainly due to the physical absorption.
