UMMC, Verkhnyaya Pyshma (Sverdlovsk region): JSC Uralelectromed (an enterprise of the metallurgical complex of UMMC) in the first quarter of this year produced 510 tons of light copper powders, which is 17% more than in the same period last year. workshops of copper powders of JSC "Uralelectromed" Anton Davletshin, high production results are due to the demand for products. Its main consumers are the automotive industry in Germany, which use it for the production of electrical products. The main feature of light powders is a low bulk density and a high specific surface area relative to powders of other brands. Their branched dendritic shape can be seen under microscopic magnification. It is she who allows light powders in chemical processes to be more active, to be effectively applied to the surface of products, which makes them unique. The general principle of the powder production technology is traditional. First, electrolysis takes place, then washing-stabilization, drying and sieving. At the end, there is a calculation of the charge according to the physical characteristics of the powder, mixing and packaging of the finished product. The main difference in properties is acquired by copper powders at the electrolysis stage, where each brand of powder has its own electrolyte composition. The production of light powders is carried out at a low concentration of copper in the electrolyte and an increased concentration of chlorine ions, which makes it possible to obtain it in such a light and with a developed surface. Those. the higher the concentration of copper in the electrolyte, the heavier the powder. In addition, light powder, unlike other types, does not go through the grinding stage, but is only sieved. Note that the copper powder workshop is the only one in the country and the largest in the world, producing about 30 brands of electrolytic powder. Among its consumers are Russian and foreign enterprises of powder metallurgy, instrument and mechanical engineering, aviation and chemical industries.
