1. 896 series degreasing agent from our company R&D which has pH=10~12, fast degreasing speed and high product efficiency. It can be operated at room temperature, energy saving, etc.
2. The products include suitable of chemical electrolytic degreasing of iron, and steel non-ferrous, Zn-Al alloys, Al-section bars. It is also as the chemical wax remover for special used to fast removing polish plaster.

The destain king has excellent inhibition for metal. The steel parts is not produce over corrosion during pickling at less than eight hours.

It can be quickly soluted for the rust and black scale, reduce hydrogen brittleness, keep metal glosses.

The strong restrain acid haze ability. Could not produce harmful gases. It can improve operate conditions, corresponding to reduce cost of equipment, extend useful life of HCl. Reduced content of HCl and throw-out of waste water.

It suitable for treatment prior to plating of low, middle and high carbon steal wire, cool tape, plates structure parts and HCl pickling of various surface treatment process.

1. NF-510 is a high effect dewatering agent, low useful concentration at 0.3-1%. Long duration of effect.
2. fast dewatering NF-501 has strong dewatering ability, parts immersing in dewater solution for 10-15 see. It can be fully dewatered.
3. Preventing rust and change color. NF-501 includes more kinds inhibitor since their synergism. It can be increased preventing rust and change color ability of deposit.
4. Easy to maintain. NF-501 has wide useful concentration range. The 0.3-1.0% concentration range with excellent dewatering performance.
   

This is a new generation dewatering product that is can be formed an abhor water film on surface of parts. Reached to fast dewatering aim. Saving times, saving electric, saving forces, the anti salt fog performance is noticeably increased due to existed abhor film on surface.

Procedure: plating → rinse double → immerse dewaterant → rinse or warm water rinse → dry

The product has excellent corrosion for resistance atmosphere, resistance acid and alkaline chemicals etc. it has high hardness, glosses chubby. The plated parts can be directly coated after rinse. Operating simply suitable for decorative of articles which used in high need for surface during process. It has excellent environment protection performance.

The products are suitable for various kinds of zinc plating layers. The beautiful appearance with blue-white in color of passivation film can be obtained by passivation treatment. The blue-white color is a prevail color in international market.It has excellent corrosion resistance. It has passed test of plating test center of China which according to GB/T10125-97, GB/T 9800-88 Standard. The neutral salt fog test more than 48 hours, available for produces which has been required for high corrosion resistance.

Performance of products is corresponding to same type products on international market.; and export to international market.

   It is has excellent corrosion resistance. The appearance showing silver-white color , process stable, operating simple.

  The passivation film has brightly colorful and lustrous, high adhesion strength. Process stable and good corrosion resistance.

The process without six-valent Cr. Suitable for environment protection. Performance of process stable. Good corrosion resistance. It can be obtained ideal color, if A-B agents are taken proper adjustment.
Note:
1. Suitable for parts with general requirement.
2. Suitable for parts with big corrosion resistance requirement. Deep blue or plate parts.

The A,B black color passivator which is produced by our company can obtained bright black passivation film on zinc deposit, it can be increased protection and decorative of zinc deposit.

   It is effectively remove metallic impurities such as Cu, Pb, Cr, Fe etc. and organic decomposition in either cyanide-free or cyanide alkaline zinc plating bath. It passed treat bath can be recovered to make-up bath level.

1. It can be selectively precipitated bivalent and trivalent Fe ions but can not precipitate Zn from plating bath.
2. Formed precipitate is little. High tability. It can not repeat solve, therefore need not immediate filtrate.
3. It without harm effective for additives and have no effect for duration and function of bath.
4. It can be also removed for Pb, Cu impurities.
   

1. According to Fe impurities in bath, calculated WN add contents by 2-4 g/L.
2. Adding slowly WN under continually agitating. Then again agitating for 20-30 min.
3. Static put 0.5-1 hours, then filter removed precipitate.
4. If without filter condition, also can drawing out clear solution of upper in bath after static put.
5. When the pH value of bath is rise, adjust to normal range and proper supplement additive.
6. If impurities too much , it can to carry second treatment.
   

It is a new product of our company. It can be obtained excellent corrosion resistance for zinc deposit. The zinc deposit immersed sealer after with passivation, its corrosion resistance is very increased.

Process is simple, easy to operate. Its quality is comparable to same product of foreign.

The clear and bright of surface after stripped of deposit. It can directly plating. Has long duration of bath. Process is stable, operate simple, fast stripping speed. W-710 additive is can be increased stripping speed.
