Abstract

The invention belongs to the metallurgical field, and in particular relates to an environment-friendly high-efficient electrolytic selenium-free manganese metal additive and a preparation method for the same. The environment-friendly high-efficient electrolytic selenium-free manganese metal additive is characterized in that: the additive is prepared by raw materials of water-soluble polyacrylamides, animal glue, polyethylene glycol, boric acids and water. The content of various raw materials by weight percent is as follows: 5 to 10 percent of polyacrylamides; 8 to 15 percent of animal glue; 30 to 40 percent of polyethylene glycol; 3 to 5 percent of boric acids; and residual water. The sum of the content of various raw materials by weight percent is 100 percent. The additive is nontoxic and non-corrosive; volatilization and so on can not be generated during the electrolysis process; the operation is convenient and safe; and the environmental protection performance is good. Moreover, the additive is used for electrolytic manganese and is characterized by high current efficiency and good product quality of the electrolytic manganese.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to an environmentally friendly and efficient additive for electrolytic selenium-free metal manganese and a preparation method thereof, which is used for the electrolytic production of metal manganese in an ammonium sulfate-manganese sulfate solution system. Background technique [0002] In 1923, A.J.Allmand and A.N.Campbell in the United Kingdom electrolyzed metallic manganese with a ceramic diaphragm. However, it was not until the mid-1940s that a suitable additive was found, and electrolytic manganese really entered industrial production. Looking at every progress in the electrolytic manganese industry, it is accompanied by the research and utilization of new additives. It can be said that additives play a pivotal role in the progress of electrolytic manganese technology. During the development of electrolytic manganese additives, SO 2 , sulfur compounds, SeO 2 , selenium-c...
