2. Main process introduction
Cathode discharge oil: remove the oil on the surface of copper wire to ensure the binding force of the coating .
Anode discharge oil: same as the cathode discharge oil.
Pickling: remove the oxide from the surface of the copper wire.
Pre-silver plating : as a pre-coating, to ensure the subsequent coating and base binding force.
Silver plating: the copper wire is coated with a uniform silver coating.
Protection: a protective film is formed on the surface of the product to prevent oxidation and discoloration of the coating during transit and storage.
3. Possible faults and correction methods for bright silver plating
| Fault phenomenon |
Cause of occurrence |
Solution |
| Uneven glossiness |
Excessive amount of brightener and auxiliary brightener |
Activated carbon treatment |
| Cloud like appearance at high potential |
Insufficient brightener |
According to the results of the Hull cell test, replenish the brightener in an appropriate amount |
| Low current zone coating slightly yellow |
Insufficient potassium cyanide |
Supplementing 2 grams/liter of potassium cyanide |
| The coating is blurry, and the plating solution is dark brown |
Organic impurity pollution |
After activated carbon treatment, filter and clarify |
