1. Good combination between plating deposit and steel wire, low brittleness, zinc loss lower to 2~8% during drawing.
2
2. The deposit thickness is up to 50~200g/m , suitable for continuous zinc plating on general steel, mid- and high-carbon
steel wire, also for wire drawing and deeply processing of the plating deposit.
3. The bath allows wide range of temperature, it has good salt resistance, no foam, stable bath is easy to operate and
maintain.
BATH COMPOSITION & OPERATION CONDITION
Zinc sulfate (ZnSO 4⋅7H | 600~700g/L |
2O) | 25~30ml/L |
SZ-75 Bath make-up | 16~18ml/L |
SZ-75 Additive | 2.5~3.5 |
PH | 10~60°C |
Temp. | 40~70A/dm |
D (continuous running) | >95% |
ATTENTION
1. When making up bath, use warm water to dissolve zinc Sulfate (ZnSO 4⋅7H 2O) and remove sediment, then add SZ-75
additive and bath make-up agent, stir it and filter, then use.
2. Steel wires must be treated completely before being plated, ensure them no rust or black ash, If the bath is circularly
filtered, the effect will be better.
3. Analyze the solution concentration periodically, If no analysis, its Beaume degree should be controlled over 30°.
4. The additive consumption is 40~60ml/KAH. Generally, producing 1MT of wire need to replenish 2000~2500ml of
additive.
5. SZ-75 bath make-up agent should be replenished periodically because of drag-out loss, its consumption is 20ml/KAH.
6. The other salt, such as Na 2SO4 and Al 2(SO 4 3) etc., are not permitted to add into bath,
