Cyanide Free Alkaline Zinc Plating Process High Concentration Good Dispersion Performance

1. DS-3000 is a cyanide-free alkaline zinc deposition process for both rack plating and barrel plating.
2. Excellent plating performance can be obtained under high concentrations of zinc and caustic soda.
3. Outstanding throwing power at all current densities, which lowers zinc consumption.
4. Fast brightening speed to form fully bright zinc deposits.

Advantage:

High concentration
Good dispersion performance of the coating
Excellent positioning performance
Good ductility
Can work at high current density
Low operating costs

Additive effect
DS 3000 cylinder opening agent is an important additive for achieving good coating and metal distribution. It can also control the internal stress of the coating and cathode current efficiency. It is used in both the production of plating solution and the replenishment of consumption during the electroplating process. In order to obtain good coating and metal distribution, it is the most important additive. It can control the cathode efficiency of different current densities. However, its dosage during tank preparation is strictly related to the concentration of zinc. 1 gram/liter of zinc corresponds to 1 milliliter/liter of cylinder opening agent. Its function is to control the internal stress of the coating. The combined use of the same brightening agent can ensure a relatively good bright coating.
DS 3000 brightener can be used in combination with cylinder opening agent to maintain brightness throughout the entire current density range.
DS alkaline zinc plating purifier can effectively purify foreign metal impurities. Its consumption is determined by the bluntness of the zinc used, and it improves the blackening and darkening function in low current density areas.
DS alkaline zinc plating regulator, which improves the effectiveness of other additives, should also be added in moderation when adding sodium hydroxide. At the same time, it improves the performance by fogging the tank solution.

maintain
For supplementation, there are two possible methods to choose from:
Select and supplement according to the optimal values of all additives: regulator, impurity remover, cylinder opener, and brightener;
A relatively easy way to supplement is to use only cylinder opening agents and additives This method is particularly suitable for supplementing the hanging plating tank, which is beneficial for decorative purposes
Appearance is very important
Recommended large processing procedures for DS 3000 environmentally friendly zinc process:
① Stir vigorously with 1-2g/L zinc powder, let it sit for 2-4 hours, then add 3-4g/L specialized activated carbon and stir for 1 hour before filtering.
② Low current electrolysis for 8-12 hours or more.
