The production of electrolytic copper powder is the same as the electrochemical principle of copper electrolytic refining, the anode is an electrolytic refining high-purity copper plate, the cathode is a lead alloy plate, a stainless steel plate or a rolled bright copper plate, and the electrolyte is a copper sulfate solution. During electrolysis, copper ions are discharged under the action of direct current to deposit on the surface of a cathode, and after the copper ions are accumulated to a certain degree, the electrolytic copper powder is scraped by a manual scraping brush regularly, so that the electrolytic copper powder falls into an electrolytic cell (electrolytic copper powder anti-oxidation technical research, Lijunzhou, Master's academic thesis of the university of south China, 1999, page 5, 3 rd paragraph 1-2 line, page 6, FIGS. 1-2 and page 6, 1 st 1-3 line, published 1999, 12 th and 31 th days; "metallic copper powder is prepared by electrolytic method", Yangyi, copper engineering, 2007, 3 rd stage, page 20, right column, 2 nd line, page 20, right column, 3 rd paragraph 1-2 line, page 21, left column, 5 th line, 3 th line, page 21, left column, 7 th line, 1 st line, published 2007, 12 th and 31 th days; "influence of process conditions on the preparation of copper powder by electric accumulation method", benefit the society and the like, beijing university of science and technology, 2011, volume 33, phase 2, page 182, right column, section 2, line 2, and page 183, FIG. 2, published 2011, 12 months and 31 days).
