The invention discloses a
lotion for removing color spots on the surface of silverware. The
lotion is mainly prepared from the following components in parts by weight: 65-89 parts of deionized water, 5-15 parts of
glycerol or glycol and 1-5 parts of nano
titanium dioxide. Nano
titanium dioxide is used as an
oxidation reduction catalyst in the
lotion, a great number of photoelectrons with strong reducing property are formed in a solution through
light energy absorption, and the photoelectrons can be used for reducing silver in color spots such as
silver sulfide and the like into elemental silver; meanwhile, nano
titanium dioxide is used for producing a great number of photoholes with strong oxidation property, and the photoholes can be reduced by
alcohol, so that no secondary
pollution is caused in the whole process.
Alcohol in the lotion is used as a sacrifice agent to be oxidized, and excess
alcohol is used as a
wetting agent, so that the catalytic activity of nano
titanium dioxide can be effectively promoted. The lotion is free of silver loss while removing the color spots on the surface of the silverware, capable of effectively treating silver plated or fine pattern silverware, convenient to operate, free of active
metal or corrosive substances to participate in reaction, and free of potential safety hazards.
