Process features
: Pearl River Delta semi-bright medium phosphorus chemical nickel has a long cycle life of up to - one cycle ( ) [The meaning of cycle is to plate out all nickel per liter of plating solution and then add it to the nickel content when the cylinder is opened. A minimum of dd can be deposited in one cycle per cycle
The highest plating speed can be reached
The loading capacity of the plating solution is large, it can accommodate up to square decimeters per liter of plating solution, and the performance is stable for a long time
Deep plating capability Strong, strong throwing ability
High hardness, strong corrosion resistance
Low porosity and no pores in the coating
Good wear resistance, better than electroplating chromium
Good weldability and can be soldered Wetted
Good electromagnetic shielding performance and can be used in electronic components and computer hard drives
Performance of electroless nickel plating
Phosphorus content: -% Resistivity: -d
Density: ./melting point :-℃
Hardness: as plated -(-r) Bonding force: much higher than after electroplating heat treatment:
Internal stress: the internal stress on steel is lower than
How to use
The product adopts internationally accepted three solutions. The cylinder is opened to analyze the consumed components of the replenishing working fluid according to the nickel ion concentration. The replenishment is extremely convenient:
Cylinder opening method
Preparation of liters of working fluid Liquid as an example
%/
%/
The remaining amount is deionized water (conductivity lower than /) and (adjustment value.-.)
Temperature: -℃
Loading capacity: .-d/
The specific method is to first calculate the volume and draw a scale on the wall in the tank. Fill half the volume with deionized water, then add % and %. Add deionized water to the bottom of the scale. Use it after a while. Adjust the value to the scale line and heat it to ℃ to plating according to the process requirements.
Operation points
Make sure the plating tank is soaked and rinsed with water before use
Keep the temperature of the plating solution at -℃
If the temperature is too low, the speed will be slow. If the temperature is too high, the plating solution will be Easy to decompose
Use . and (%) to adjust the value to keep the value between .-. to ensure that the plating speed is too low, the plating speed will be slow, and if it is high, the plating solution will be easy to decompose. It is best to use a meter to control.
Avoid Bringing in heavy metal impurities and surfactants
