T3-T8 aluminium profile with oxidation dyeing surface treatment

T3-T8   aluminium profile with oxidation dyeing  surface treatment 

Anodic oxide film of aluminium profile or aluminium products consists of a large number of hexagonal cells perpendicular to the metal surface, There is a membrane hole in the center of each cell, It also has strong adsorptive force, When oxidized aluminium products are immersed in dye solution, Dye molecules enter the pore of oxide film by diffusion, At the same time, covalent bonds with oxide film are formed which are difficult to separate with Ionic bond , This bonding is reversible. Desorption occurs under certain conditions. Therefore, after dyeing, Must be sealed, Fixation of dyes in membrane pore, Increasing Corrosion Resistance of Oxide Film by Means of Synchronization, Wear resistance and other properties
