To achieve excellent coating performance, it is crucial to properly control the pH value of the solution when using the copper pyrophosphate brightener.
The optimal pH range of the solution is 8 to 9. Beyond this range, the pyrophosphate will decompose to form orthophosphate or form a precipitate.
Meanwhile, if the pH value is too high, the anode dissolution and the current density range will narrow. When the solution is operated under high pH conditions, increasing the ratio of P2O7/Cu can eliminate the tendency of the coating to become rough. During actual operation, the pH value can be easily controlled within the range of 7 to 9, without chemical decomposition, and the solution has a strong buffering effect.
When using Bigely copper pyrophosphate brightener, in order to achieve a high-quality coating, one can learn how to lower or raise the pH value under the guidance of our engineers.
