The invention aims to provide a nickel removing agent and a nickel removing method. The nickel removing agent is used to remove the nickel on the surface of the oxide film on an aluminum anode. Afterthe treatment, the oxide film on the aluminum anode has a strong color resistant property and an excellent anti-corrosion performance. The invention provides a nickel removing agent, which is characterized by comprising vanadium compounds and aluminum salts and is used to remove the nickel on the oxide film on an aluminum anode, whose pores have been sealed.
Description
Technical field [0001] The invention relates to a nickel removing agent and a method for removing nickel. Background technique [0002] In the past, in order to improve the stain resistance to fingerprints and other stains, to improve the chemical resistance to alkalis, acids, etc., to improve the corrosion resistance to the natural environment, air pollution, etc., and to stably protect the organic dyed oxide film. Dyes are used for sealing anodized coatings of aluminum and aluminum alloys (hereinafter sometimes simply referred to as "aluminum"). [0003] As the sealing treatment method of aluminum anodic oxide film, the sealing treatment using pressurized steam, the sealing treatment using boiling ion exchange water, the sealing treatment using metal-containing aqueous solution, and the use of nickel acetate or nickel fluoride are generally adopted. Nickel salt sealing treatment (hereinafter, also referred to as "nickel sealing".), especially nickel sealing, because it can be se...
