The high phosphorus electroless nickel plating solution contains both metal salts and reducing agents in a metastable state. Maintaining the plating solution during use can improve the service life of the plating solution and the quality of the coating. The high phosphorus chemical nickel plating solution should be maintained as follows:
1. Regularly measure the temperature and pH value of the plating solution, maintain them within the operating range, and avoid significant fluctuations.
2. Ensure that the nickel content in the plating solution is within the operating range. If it is insufficient, it should be replenished in a timely manner and the replenishment interval should be shortened as much as possible to reduce the amount of single addition; Alternatively, automatic tracking and analysis can be used for better results.
3. The plating solution should be filtered regularly to remove harmful particle components from the plating solution.
4. To avoid prolonged high-temperature no-load or severe overload of the plating solution, the plating tank should ensure even distribution of the plated parts.
5. When the plating solution is not in use, it should be covered to prevent harmful substances such as dust from falling in.
6. Regularly export the plating solution and soak the plating tank in dilute nitric acid to remove sediment.
7. The plating solution should avoid adding or introducing harmful impurities such as other organic compounds and heavy metal ions.
8. A record book should be equipped during workshop production to promptly record the addition of high phosphorus chemical nickel concentrate, pH value adjustment, variety and quantity of plated parts, and other operational details, and keep them.
The above is the daily maintenance of high phosphorus chemical nickel plating solution during use, which can improve the service life of the plating solution and the quality of the coating.
