Barrel polishing method applied together with chemical polishing
专利汇可以提供Barrel polishing method applied together with chemical polishing专利检索，专利查询，专利分析的服务。并且PURPOSE:To improve the efficiency and quality of barrel polishing by using a proper amount of persulfate as a compound for the barrel polishing instead of water and a compound conventionally added upon polishing the barrel. CONSTITUTION:A polishing material, persulfate, and water, and a workpiece made of copper or a copper alloy, or a workpiece made of steel are inserted into a polishing tank, for barrel polishing. Sodium persulfate, potassium persulfate, and ammonium persulfate are proper for a chemical polishing agent, and sodium persulfate is most suitable from a viewpoint of a fact that copper ions can be entirely removed by neutralization therefrom without any production of a copper ammonium complex in the case of waste water disposal in industrial mass-production. The concentration of the chemical polishing agent is effective in 4-150g/l, and that other than this range is not practical because the effect of smoothing a workpiece is reduced or its surface is made rough. The surface of the workpiece after barrel polishing is colored brown for copper or a copper alloy or gray for steel, but it is cleaned with a dilute acid solution, and then subjected to a glazed finish by the usual barrel polishing.，下面是Barrel polishing method applied together with chemical polishing专利的具体信息内容。
