联合制碱法是将合成氨生产和纯碱生产联合起来制取纯碱和氯化铵肥料的新工艺。由于联碱生产介质对设备的腐蚀严重,因此经常造成停车,污染环境,而且每年要消耗大量钢材,致使这一新工艺没有得到应有的发展。为了有利于经济合理地解决腐蚀问题,我们对联碱生产介质的腐蚀作用进行了研究,本文介绍这些研究结果并提出一些初步看法。联碱生产介质的腐蚀作用,是通过研究金属在介质中的电位和阴、阳极极化曲线,并测定各种因素对介质的腐蚀作用的影响而 The combined soda production process is a new process that combines the production of ammonia plant and soda ash production to make soda ash and ammonium chloride fertilizer. Due to the serious corrosion of the equipment by the alkali-based production medium, it often causes parking and pollutes the environment, and consumes a large amount of steel every year. As a result, the new process has not been properly developed. In order to facilitate the economic and reasonable solution to the problem of corrosion, we have studied the corrosion effect of the alkali-producing media. This paper presents the results of these studies and puts forward some preliminary observations. The effect of the alkaline medium on the corrosion of the medium is determined by studying the potential of the metal in the medium and the anodic and cathodic polarization curves of the medium and determining the corrosion effects of various factors on the medium
