Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of etching solution production, in particular to an automatic feeding device for etching solution production. Background Art
[0002] Etching solutions generally refer to those liquids that can dissolve, erode, or damage the surfaces of other substances (such as metals, plastics, glass, etc.). These liquids often contain strong acids, strong bases, oxidants, or other reactive chemical substances. Therefore, they must be handled with great care during use and mixing to ensure the safety and effectiveness of operations. When the etching solution is fed into the mixing tank for mixing, the added materials are prone to impact each other. Unstable mixing may lead to violent reactions, such as heat release and generation of toxic gases. Moreover, unstable mixing may result in waste of the etching solution because some liquids may become ineffective or deteriorate during the mixing process, which will increase production costs and reduce efficiency. For this reason, this application proposes an automatic feeding device for etching solution production to solve the above problems. Content of the Utility Model
