Acid salt activator
BC-629 acid salt activator
BC-629 salt activator is a water-soluble acid powders, which can replace most of the plater Field acid used. Has a high stain tolerance and rapid penetration of oxides and dirt. Use BC-629 acid salt activator to make the surface drier, brighter, without sludge, so that the coating has better adhesion and brighter.
Operating conditions and equipment:
Concentration :30-60 g/L
Temperature :Room temperature to 80°C
Tank :Koroseal, rubber, polyethylene, polypropylene, PVC or lead lining
Heating coil :Karbate, graphite or lead
Steps to build a new bath:
Clean the preparation tank and fill it with water, equal to 2/3 of the tank capacity.
Add the required BC-629 acid salt activator and mix
Inject water to the required operating level of the bath and continue mixing until completely dissolved
BC-629 acid salt activator solution can be used as pickling solution to remove oxides, rust, heat treatment and welding scales.
BC-629 acid salt activator can be regarded as a bubble liquid used for activation before electroplating. It is suitable for zinc alloy, aluminum-lead alloy, iron, cast iron, ductile iron, type 200, 300 and 400 stainless steel.
Pickling iron parts before nickel plating120 g/L,15-30 seconds
The precursor acid phosphate wash iron240 g/L,1-3 minutes
Pickling zinc alloy workpieces before copper plating30 g/L,15-30 seconds
Pickling zinc alloy workpiece before passivation60 g/L,10-30 seconds
Pickling copper-plated workpieces before nickel plating60-120 g/L,
10 seconds to 1 minute
Pickling and polishing brass workpieces before nickel plating 60-120 g/L,10 seconds to 1 minute
Reagent: Bromocresol green indicator
NaOH 0.5N standard solution
a. Pipette 10 mL sample into a 250 Erlenmeyer flask, and add 50 mL water.
b. Add 5 to 10 drops of bromocresol green indicator.
c. Titrate with 0.5 N sodium hydroxide solution.
d. Calculation: mL 0.5N NaOH x 7.34 = g/L BC-629 acid salt activator
