Non Cyanide Zinc Plating Chemicals - China

1 - Characteristics,

Cyanide Free, environmental friendly

It can achieve elegant and bright zinc

plating over a wide range of current density

Extremely even plating thickness, with high

dispersion capacity

Plating is extremely soft and easy to

chromate passivation, the deformation process

can be processed after plating

Process stability, high tolerance for

impurities and good temperature resistance

Plating solution is simple and stable,

without any control hassle

Suitable for hanging galvanized and roll

galvanized production line

3 - Plating solution preparation methods,

A.

Put one fifth of water into the plating

bath, adding required sodium hydroxide and

keep stirring till complete dissolution;

B.

Then mix zinc oxide with water into a

paste, slowly pour into the bath, stir to

completely dissolve

C.

Once the zinc oxide is completely

dissolved, add water to the the required

volume;

D.

Continuous electrolysis for 30 minutes

using Wavy false cathode at a low current

density (0.2 A/dm2)

E.

Finally, adding the calculated amount of

various additives, stir well, then the

plating is ready to start

4 - Equipment Requirements,

Plating bath: Steel tanks lined with plastic

or plastic tank.

Circulation filter: The circulation filter

can prevent rough coating.

5 - Additive function and complementary,

1) Polish agent HN-NK1: Fine crystalline

plating can be achieved over a wide range of

current density.

Insufficient amount can

result in low potential zone with lightless

and a small amount of gray fog, in case of

excessive, cathode hydrogen evolution severe

and result in low current efficiency.

2) Additive HN-NK2: The Plating can improve

brightness and leveling, prevent white

Plating in a high potential zone.

Insufficient amount can result in Less

brightness in middle potential zonet, and

whitish in high potential zone; While

excessive can result in cathode hydrogen

evolution severe, and low current efficiency.

3) Impurity agent HN-NK3: Special anti-hard

water and Metal impurity agent, the water can

complex Ca, Mg and other metal impurities,

Thereby reduce the impact of metal impurities

contamination
