一、前言在我国,浓硫酸中不锈钢的阳极保护技术正在工业上推广应用。然而关于浓硫酸内碳钢的阳极保护,在国内还少见报导。为探索这一问题并作一些必要的技术准备,我们在实验室内研究了国产普通碳钢在93%硫酸内的阳极极化行为。二、实验方法研究电极采用A3碳钢。试验介质选用硫酸生产过程中常见的93%硫酸。电极的制备,溶液的配制及实验方法与装置同文献[1]。
I. Preface In our country, the anode protection technology of stainless steel in concentrated sulfuric acid is being promoted and applied industrially. However, the anode protection of carbon steel in concentrated sulfuric acid is rarely reported in China. In order to explore this issue and make some necessary technical preparations, we studied the anode polarization behavior of domestic ordinary carbon steel in 93% sulfuric acid in the laboratory. Second, the experimental method Electrode A3 carbon steel. Test medium selection of sulfuric acid production process common 93% sulfuric acid. Electrode preparation, solution preparation and experimental methods and devices with the literature [1].
