.Process features: Fast brightening and leveling capabilities, fast deposition speed
Soft coating, bright white color and beautiful appearance
High throwing ability, strong low potential coverage ability.
Wide operating range, single brightener addition, easy to control and high impurity tolerance
Suitable as the bright nickel base layer for chrome, bronze, gold, silver and other metals.
For most nickel plating processes, this brightener can be directly supplemented and the cylinder rotated

3. Plating solution preparation method:
Inject two-thirds of the water into the preparation tank, heat the water to -℃, add the required nickel acid and chloride nickel, stir to completely dissolve, add nickel carbonate or sodium hydroxide solution, adjust the pH to...
Add .ml/L hydrogen peroxide (diluted with water first) and .g/L activated carbon, stir for several hours and let it sit overnight, then filter the plating solution into a clean electroplating tank and clean the filter pump. Clean, install activated carbon and set aside.
Add the required boric acid, and then use dilute acid to adjust the value of the plating solution to.
Use a wavy false cathode to electrolyze continuously at a low current density (.Ampere/square decimeter) for more than one hour, or until the low potential color changes from dark black to light gray.
Finally add the above various additives and you are good to go.
.Equipment requirements:
Plating tank is a steel tank or plastic tank lined with plastic.
The circulating filtration filter pump can filter the plating solution at least four times in one hour. Every working hour, put .g/L of activated carbon in the filter, the effect will be better.
