一、前言铝酸钠溶液的炭酸化分解率是氧化铝生产过程的重要技术经济指标之一。到目前为止,控制这一重要技术经济指标主要是依靠化学分析方法所取得的结果。因此,它不但大大地增加了分析检验人员的劳动强度和需要时同,而且给炭酸化分解工段实现自动化 First, the preface Sodium aluminate solution carbonation decomposition rate is one of the important technical and economic indicators of the alumina production process. So far, the control of this important technical and economic indicators mainly rely on the results of chemical analysis methods. As a result, it not only greatly increases the labor intensity of inspection inspectors and needs the same time, but also to automate the carbonation decomposition section
