1. Zinc Nickel Plating Coating Process

1 Mix Ratio

Pack A:16.0 kg

Pack B:24.0 kg (the quantity can be increased appropriately if spray coating)

Pack C:0-50 g (according to different viscosity demand )

2

Mixture Method

Before Mixture, Keep weighted A&B into the water bath at 25±2℃ , then stir A to make metal slurry disperse uniformly by frequency mixer ,after A is fully evenly dispersed, reduce the agitating speed to 60r/min, and add B.

3.2.2

Add B to the stirring A slowly. At the moment ,the barrel temperature will go up,when it reaches 35℃, startup refrigerating device to keep the barrel temperature constant at 35℃.

 

3

Stir the mixture about 1~2 hours fast after B added, then add C. C should be powdered if lump exist.(The barrel temperature should not be lower than 30℃, otherwise C will not be dissolved sufficiently .)Then stir 12 hours continuously.

4

The coating should be filtrated by 80~100 mesh stainless steel screen before pouring into dip barrel.

5

Temperature control device should be equipped with dip barrel to keep the temperature of coating at 22±2℃.(If temp. is too high, the paint is liable to deteriorate, and viscosity will be effected.) The coating should be stirred circularly to keep evenly dispersed.

6

Test density,PH,Temperature,Viscosity and Cr6+ content of coating every 8 hours if operate continuously.

 

7 Technical data

No. Item Data
1 PH 3.8-5.2

8 Mix Diagram

Caution: Temperature should be controlled in above operation.

 

 

9 Attentions

Other chemicals such as any kinds of acid, alkali salt can not be mixed into coating, for these can activate Zn & Al plate to aging the coating.

Avoid irradiation of sunshine and ultraviolet ray for long time when operating, otherwise it will accelerate aging or polymerization of the coating .

It is very important to control the temperature of coating. If the temperature of coating changes when operating, it will effect the viscosity, then effec the coating quatity on workpiece. So the relations among temperature,viscosity and spinning process shoud be controlled well when coating.

The viscosity will be different if coating method is different. Choose low data if spray coating,and choose high data if dip spin coating.

 

9 Packing

Pack A: 16kg/ Metal Barrel Pack B: 24KG Plastic Barrel Pack C: 5.0kg metal barrel

 

10 Quality guarantee period

Before compound 6 months at 20℃

After compound 40 days at 20℃ ( It can be recycled if adding fresh coating continuously. )

It should be stored under 20℃ if not in use.
