.Process features: An innovative generation of ultra-highly concentrated synthetic formula, the coating has a high leveling degree
The coating is extremely bright and flexible
The plating solution has good dispersion ability and the leveling ability is very good
The coating has no needles holes, with good corrosion resistance
The plating solution is stable, easy to operate and control, and has low maintenance costs
The high concentration of supercopper plating additives is suitable for the electroplating of steel parts, zinc alloy die-casting parts, and plastic parts. , after necessary pre-treatment (such as alkali copper plating), it can be used as an economical and practical bright intermediate coating.

3. Preparation method of plating solution:
Add half of the water to the preparation tank. The content of water used for heating to -℃ should be less than mg/L, and add the required stirring. Let it dissolve completely.
Add .g/L activated carbon, stir for more than an hour, then use a filter pump to filter the plating solution into a clean electroplating tank, and add water until it is close to the water level.
Slowly add the required pure acid while stirring vigorously to keep the temperature of the plating solution not exceeding ℃.
After cooling the plating solution to ℃, add or according to the content in the plating solution to make the content reach the standard value.
Finally, add the above various additives, electrolyze with a current of .Ampere/square decimeter for about an hour, and then electroplating can begin.
.Equipment requirements:
Plating tank: a steel tank or plastic tank lined with polyvinyl chloride or other various plastics.
Cooling equipment: If the temperature of the plating solution is too high, it will not only increase the consumption of brightener, but also reduce the brightness of the low potential area, so it is very necessary to equip appropriate cooling equipment.
Circulation filtration: Floating objects in the plating solution such as dust, grease, etc. will cause the coating to be rough, produce pinholes, or reduce the brightness. It is best to use continuous circulation filtration of the plating solution. The filter pump will filter the plating solution within at least one hour. The liquid was filtered four times.
