Description
Technical field
The present invention is to provide the inner wall of kettle finishing method of oil, chemical industry, chemical fertilizer, field of medicaments use, specifically a kind of inner wall of kettle electrolytic polishing method.
Background technology
Electropolishing is that the surperficial selectivity anode in the electrolytic solution of applied metal melts and reaches a kind for the treatment of process of polishing and smooth appearance.When processing, by the control to current density, electrolytic solution viscosity and electrolyte temperature, metal is melted in the electrolytic solution, pocket enters passive state and melts, and boss activity melts, finally reach certain balance, by adding light agent and anodic polarization effect in electrolytic solution, reach the object of leveling polishing, surface brightness can reach extreme value.Main electropolishing mechanism has mucous membrane theory and passivation film theory.Smoothness and the thick liquid film of metallic surface electropolishing are closely related, and luminance brightness and solids passivation film closely related.Metallic surface electropolishing can be subdivided into macroscopic view leveling and microcosmic flattens two processes, and the change of these two processes and anode potential is closely related, and when it reaches a kind of dynamic balance state, surface brightness can reach extreme value.Compared with mechanical polishing, electropolishing can reduce the stress on metal inside and surface, and smooth finish after electropolishing and planeness keep more permanent than mechanical polishing.
At present, along with the development of domestic and international electropolishing technology, the research of the domestic electrolytic polishing process to metal works is more and more ripe, but can't realize the disposable integral electropolishing of cylindrical kettle and ellipsoidal head, especially main equipment, not yet has correlation technique at home.
