Aluminum sheet manufacturers to introduce the surface polishing process of mirror aluminum sheet
- 2017-03-09 10:02 -
Similar to this large aluminum factory, the production requirements of the mirror aluminum sheet surface quality of Mingtai aluminum are high, in the production process, how to control the surface quality of the rolled aluminum mirror polishing become manufacturers focus on the pursuit of the direction. Process and production practice of aluminum electrolytic mirror polishing and electrolytic polishing material surface give high brightness effect, and show a high specular reflection performance, it is suitable for Industry and technology and the field of interior decoration.

Aluminum processing enterprises generally use aluminum after mechanical polishing, then the acid chemical polishing and electrochemistry polishing of two methods. The production of traditional acid chemical polishing, due to the presence of nitric acid, will produce yellow NO2 gas, a large number of toxic and serious environmental pollution. Improved acid chemical polishing, will also produce a lot of white smoke, and have very big pollution to the environment. Acid chemical polishing were introduced in recent years, without nitrate does not produce toxic gases, but the polished aluminum surface brightness slightly worse than acid polishing or electropolishing. Acid chemical polishing were introduced in recent years, without nitrate does not produce toxic gases, but the polished aluminum surface brightness slightly worse than acid polishing or electropolishing. The traditional electrochemical polishing should add chromium ions, and make a serious pollution of the environment. For the polishing process, the current density is reach 20 ~ 30A/dm2, and has a waste of energy. Now, our company uses phosphoric acid as the main, and adds polishing agent electrochemical polishing process. The process has the advantages of no smoke, no toxicity, energy saving, low current density, no discharge, and tank liquid can lbe used in a long term.
