Brightener 96 for Cyanide Zinc plating

 

 

PROPERTIES

 

 

1. Wide bright area, bright deposit can be obtained when current density is 0.2~2A/dm2.

2. Strong throwing power, uniform bright deposit can be obtained on the complex parts, especially suitable for barrel plating.

3. Suitable for low-chrome passivating, it can lower pollution over 90% comparing with traditional Cr6+ pollution.

4. Suitable for high, medium and low cyanide plating bath.

5. It doesn’t contain aldehyde, it is stable and has low consumption in strong alkaline solution.

TECHNICAL PROCESS:

 

 

Acidic degreasing and derusting → rinse → alkaline chemical degreasing → hot-water washing → flowing cool water washing → activate(10%HCl) → rinse → bright zinc plating → recycle → rinse → neutralization (2~3% HNO3) → low-chrome passivation → rinse → drying (60~80ºC)

 

 

BRIGHTENER REPLENISHING:

 

 

1. On the natural working condition, when temperature range is 23~43ºC, brightener consumption is 100~150ml/KAH.

 

  2. Replenishing brightener little and normally, when barrel plating, replenishing it within half an hour before leaving bath, it can assure stable quality and low brightener consumption.
