HL-95 Potassium Chloride Zinc-plating Additives A

 

HL-93 high temperature resistance potassium chloride zinc-plating softening agent

Packing specifications：25kg/plastic drum or 200kg/plastic drum or 1 ton plastic drum

 

 

1. In the normal production process, potassium chloride, boric acid and zinc chloride are analyzed and adjusted once a week.

2. HL-93 brightener should be added according to the consumption of 60-80 ml per KA. h. When adding, it is necessary to dilute 2-3 times with plating solution.

3. HL-93 softener is generally only added when adding potassium chloride, each add 1 liter potassium chloride corresponding supplement HL-93 softener 80 ml or add 80 ml per KA. h.

4. In the normal production process, the PH value may be gradually increased, dilute hydrochloric acid can be used to reduce the PH value.

5. In the continuous plating process, the plating solution will accumulate a small amount of iron, at this time must be added to dilute hydrogen peroxide, and then filtered to remove iron impurities.

6. The first grade galvanized anode should be used. Absolutely can not use iron plate and stainless steel plate as insoluble anode, titanium blue will also be corroded, can not be used.

7. when the workpiece falls into the bath, it should be taken out in time, especially the rolling barrel must often use magnets to suck up the iron rot at the bottom of the bath.
