    配方类型: METAL TREATMENTS
    配方说明: Citric/Persulfate Desmutter for Aluminum (No.2)
    配方组成: Ferric Sulfate/0.5
    Ammonium Persulfate/5.0
    Water/84.5
    Ammonium Bifluoride/0.1
    Citric Acid (anhyd.)/10.0
    配制方法: Note: This formula is considerably more aggressive than Formula No.1. The persulfate must be replenished daily. Use at room temperature with vigorous agitation.
    Note: Citric acid is used in conjunction with persulfate salts for the removal of black smut from aluminum-copper alloys after cleaning with caustic or a nonalkaline cleaner. The persulfate oxidizes the copper to a soluble form. The citric acid then chelates the copper preventing redeposition on the aluminum. These systems do not attack the base metal aluminum.
