Anodized aluminium Angles profile 

  In order to improve the decorative effect of surface treatment and ensure the smooth progress of subsequent aluminum surface treatment main process anodizing, surface pretreatment of aluminum is indispensable. The alkaline washing process involves placing aluminum profiles in a strong alkaline solution mainly composed of sodium hydroxide for etching reaction. The purpose of this process is to further remove surface impurities, thoroughly remove the natural oxide film on the aluminum surface, and expose the metal substrate, laying a good foundation for the subsequent surface treatment technology of anodizing to generate a uniform anodized film.   Anodized angle aluminum profiles refer to angle aluminum profiles that have been anodized. This treatment method can improve the corrosion resistance, wear resistance, and hardness of the material, while also enhancing its decorative properties. Anodic oxidation treatment is an electrochemical process that forms a layer of aluminu…
