Sodium Saccharin Dihydrate for Electroplating
Sodium saccharin is widely used in the electroplating industry, especially a lot
of exported saccharin sodium is used in the electroplating industry. Sodium
saccharin used in electroplating industry accounts for a large part of the output
of saccharin sodium in China.



So what are the uses of electroplate grade sodium saccharin dihydrate?
Electroplating nickel brightener is generally divided into brightener and UESS:
brightener is mainly composed of nickel intermediate compound; The UESS is
composed of nickel intermediate and sodium saccharin. Sodium saccharin, chemically
known as Sodium O-Benzoic Sulfimide, is a primary brightener in nickel plating,
which can make the coating crystal fine, increase the ductility of the coating,
and expand the current density range of the coating. The amount of sodium
saccharin dihydrate in the UESS is usually controlled at 150-200 g/l according to
different requirements.



This is to be able to make electroplating products bright. At the same time, the
electroplating grade sodium saccharin dihydrate can also improve the softness of
electroplating products. Therefore, many electroplating manufacturers will use
sodium saccharin when producing electroplating products. However, Its high or low
content has a great influence on coating quality. Too low saccharin content not
only easy to appear brittleness coating, and often in the electroplate tip or
protruding parts appear mist. At this time, we can carry out a supplementary test
in hull cell. By adding a small amount of saccharin in hull cell to verify, if a
small amount of saccharin is added, the mist phenomenon of the electroplating
parts will be improved. And it can be adjusted according to this amount, but
saccharin should not be added in excess. The content of saccharin in the nickel
plating cylinder is easy to handle and only needs to be added to the process
standard. However, it is not so easy to remove it quickly if excessive is added.
Let me talk about the treatment of saccharin overdose. In practice, it was found
that the commonly used treatment methods such as hydrogen peroxide and potassium
permanganate oxidation could not effectively remove saccharin.



However, activated carbon adsorption can be used to effectively remove saccharin
from the electroplating solution. We also found that the adsorption effect of
carbon powder on bran essence has little influence on treatment time and
temperature, but is related to the amount of activated carbon. When the
concentration of saccharin in the plating solution is 1g/L, the maximum amount of
saccharin can be removed by 1g powdered activated carbon.



Otherwise, the surface of bright nickel plating can not see what the problem, but
will be in the subsequent chromium plating process will appear mist. This is
called fake burning.



The uses of electroplated sodium saccharin dihydrate are basically the above
points. Brightening and softening make the product look more beautiful, and make
post-maintenance easier.



It should be noted that when we use industrial saccharin natrium, we need to melt
it. Due to its high melting point, we need to heat it. What's more, when we are
using it, we need to pay attention to the environment. This is because industrial
sodium saccharin loses its value when heated in an acidic environment.



As the largest export of saccharin sodium, electroplating grade sodium saccharin
has a good market prospect. If you have any questions, please contact us.
