Embodiment Construction
[0024] The invention provides an anodic oxidation dyeing process for aluminum extruded profile products with many blind holes, which modifies the oxidation parameters of the common anodic oxidation process, reduces the electrolyte concentration and temperature range, and adds a pre-dyeing treatment agent before dyeing , choose the appropriate dye for staining. The new process steps are:
[0025] Top piece, degreasing, water washing, cleaning + spraying, alkali etching, water washing, cleaning + spraying, ultrasonic cleaning, pure water washing, anodizing, cleaning, cleaning + spraying, pure water washing, pre-dyeing treatment, pure water washing , dyeing, pure water washing, nickel salt sealing, cleaning + spraying, pure water washing, vacuum drying, the next piece.
[0026] Take the oxidized Parker series products of our company as an example: After the product is hung, the degreasing process takes 3-5 minutes to go through one cleaning, one cleaning + spraying, the time is ...
