众所周知,氟化镁乃是工业铝电解槽一种良好的添加剂。早在40年代初,国外不少科学家从事这方面的试验研究工作。以后随着铝工业的迅速发展,对其研究更加广泛和深入。苏联的别略耶夫,我国的邱竹贤教授对工业铝电解槽上添加MgF_2的研究积累了丰富的经验,在指导生产实践,改善电解质物理化学性能方面取得了显著的效果。到目前为止,添加MgF_2,在我国、日本、苏联、西德等国得到广泛的应用。所异之处仅是添加量有差别。本试验是将MgF_2添加量从5.5％增大到7～8％(重量)。试验是在阳极电流密度为0.72安
As we all know, magnesium fluoride is a good additive for industrial aluminum electrolysis cells. As early as the early 1940s, many foreign scientists engaged in experimental research in this area. With the rapid development of aluminum industry later, its research is more extensive and in-depth. Bieyeyev in the Soviet Union and Prof. Qiu Zhuxian in our country have accumulated rich experience in the study of adding MgF 2 to industrial aluminum electrolyzers and have achieved remarkable results in guiding production practice and improving the physicochemical and chemical properties of electrolytes. So far, adding MgF_2, in China, Japan, the Soviet Union, West Germany and other countries have been widely used. The only difference is the amount added. This test is to increase the amount of MgF_2 from 5.5% to 7 to 8% by weight. The test is conducted at an anode current density of 0.72 Amps
