A customer inquired that during the production process of using zinc nickel alloy brightener, the sodium carbonate content in the plating solution should be controlled within the range of 50g/L.
We all know that chemical nickel plating solution can deposit nickel phosphorus alloy coatings on the surfaces of iron, steel, zinc alloys, aluminum alloys and copper alloys after zinc immersion treatment.
In the production process of using chemical nickel plating solution, it is inevitable that there will be unqualified workpieces. So how do we remove the chemical nickel plating layer from these workpieces?
A customer inquired that during the production process of using high phosphorus chemical nickel plating solution, they would require the workpiece to undergo a nitric acid resistance test to determine the corrosion resistance of the chemical nickel plating layer.
Due to the fact that many plastic workpieces have a smooth and bright surface, some workpieces can obtain a uniform and bright chemical nickel coating without the use of brighteners when using alkaline chemical nickel plating solution for production
Many customers encounter this problem during the production process of galvanized color passivation agents.
