Abstract:
Because of distinctive properties, such as dendritic structure, high green strength, and low oxygen content, the electrolytic copper powder has been widely used in aviation, aerospace, national defense industry and other domains. But at present, energy consumption of the electrolysis process in copper powder production is high, and the current efficiency is only about 90%. Therefore£¬the decrease in energy consumption in the electrolysis process has become the major bottlenecks to the development of the enterprises. In this paper, a new electrolysis cell with different liquid inlet arranged on the sides (inlets was paralleled with the plate electrode) and ends (inlets was vertical with the plate electrode) of the cell was manufactured. Then, the effect of flow changes in a different liquid inlet on the current efficiency, energy consumption and properties of copper powder was studied. The experimental results showed that the electrolytic process had the highest current efficiency and lowest energy consumption when the flow rate is 1.5l/min in the paralleled inlet and 0.5 l/min in the vertical inlet. Under the optimal conditions, the current efficiency, energy consumption and copper powder size were 96.68%, 733.7186 kw∙h/t and 76.831um respectively. This means an obvious rise in current efficiency and decrease in energy consumption compared to traditional feeding method.
