一、前言关于隔膜法食盐电解槽材料的腐蚀,有过一些研究,然而低碳钢在这种电解槽的阴极电解液中的腐蚀行为文献上很少见到报导。众所周知,隔膜法食盐电解槽的阴极电解液主要含NaOH和NaCl。由于阳极室中Cl_2参与一系列化学副反应,产生的NaClO及NaClO_3可通过隔膜进入阴极室。Hine等人认为在阴极操作条件下,ClO~-可在阴
I. INTRODUCTION There have been some studies on the corrosion of diaphragm electrolyzer salt electrolyzers. However, the corrosion behavior of mild steel in the catholyte of such electrolyzers has rarely been reported in literature. It is well-known that the catholyte of diaphragm electrolysis cell contains NaOH and NaCl. Since Cl_2 in the anode chamber is involved in a series of chemical side reactions, the resulting NaClO and NaClO_3 can enter the cathode chamber through the membrane. Hine et al. Conclude that under cathode operating conditions, ClO ~ - may be in the shade
