High filling copper acid process

High filling copper acid process

A, features,

1, the introduction of foreign advanced technology and raw materials, light speed is fast, go in a good position, with an excellent low electric leveling ability. 

2, the bath is stable, easy to control, easy to operate, light agent consumption is small. 

3, the operating temperature range is wide, 20-40℃ can obtain better results. 

4, coating light consistent, not easy to produce pinhole. 

Second, the plating process of high filling acid copper process

Dividing range standard

Copper CuSO4∙5H2O (g/L) 180-220 200

Sulfuric acid H2SO4 (g/L) 50-80 70

The chloride ion, CL- (mg/L) 60-150, 100

Hdr-68a (ml/L) 0.4-0.6 0.6

Hdr-68b (ml/L) 0.3-0.5 0.5

Hdr-68mu (ml/L) 6-10 8

Temperature (℃) 20-40 28

Anode current density (A/dm2) 1-6

Cathode current density (A/dm2) 1.5-8

Air stirring

Voltage (V) 3 minus 9

Preparation method of plating solution

1. Inject two-thirds of the pure water into the reserve tank (check whether the pure water contains chlorine ions). 

2. Add the amount of copper sulfate required by the opening cylinder and stir to dissolve. 

3. Add the required analysis pure sulfuric acid. 

4. Add high-purity activated carbon powder (2-5g/L), stir for 4 hours, set aside and filter. 

5, electrolysis for 6 hours, adding the amount of chlorine ions and additives needed to open the cylinder. 

6. Normal production can be achieved after qualified plating. 

Iv. Consumption: high filling copper acid process is calculated as per thousand ampere-hour consumption

Hdr-68a: 50 ~ 70ml / 1000 ampere-hour

Hdr-68b: 30 ~ 50ml / 1000 ampere-hour

Hdr-68mu: 60 ~ 80ml / 1000 ampere-hour

Ss ="font1">T impurity removal water: suitable for nickel plating agent, especially for zinc-based alloy parts, can remove heavy metal impurities in nickel plating solution.

In particular, direct addition of zinc has a significant effect.

Usage: 0.3 ~ 0.6 ml/l

3, hdr-28p high speed leveling agent: when the plating requirements are particularly good leveling, with the main light agent at the same time, you can get a particularly bright and plump coating.Generally press the main light agent consumption of 10%.
