Stainless steel dedicated copper plating liquid  ， stainless steel surface chemical plating copper ， copper plating liquid for dedicated stainless ssteel，  metal surface treatment solution ， stainless steel copper plating agent 

(A) Product Code: Q / YS.129 (Yi Shun brand)

(B) The process applies to:

2 #, 3 #, 4 # at the beginning of the stainless steel surface chemical copper plating, such as 201 #, 207 #, 304 #, 301 #, 410 #, 411 #, 430 # and other stainless steel are suitable This process. Copper layer with excellent bonding, no blister, can not afford to skin, can be bent without losing skin.

(C) the necessary chemical products and equipment in the process:

1, industrial-grade hydrochloric acid.

2, degreasing cleaning agent.

3, polishing machine.

4, Yi Shun brand stainless steel special copper liquid(Q / YS. 129), excessive sexual coating, excessive sexual coating.

5, Yi-shun licensing general-purpose chemical copper plating liquid (Q / YS.118), thicker copper, thicker copper.

6, other: copper blackening agent, drawing machine (or scouring cloth).

Plastic containers, Varnish (paint), drying equipment.

(D) copper plating process:

1, stainless steel degreasing, polishing process.

2,hydrochloric acid soak 10 seconds -2 minutes, hydrochloric acid concentration of 10% -15%.

3, washed, into the stainless steel special copper liquid Q / YS.129 room temperature (35 ℃ -55 ℃) soak for 1-3 minutes.

Stainless steel special copper plating liquid (Q / YS.129) preparation method: add water twice, first cooling, then add 3 ~ 5 g / kg of stainless steel special copper additives, stir quickly, you can use.

4, after washing, into the general type of chemical copper plating liquid(Q / YS.118)

Copper plating conditions A: B: water = 1: 2: 3, temperature 30-45 ℃.

Reference plating speed of 20um / h, copper plating process should be properly stirred, filtered copper water and flip the workpiece. The median value should be adjusted PH, appropriate additional A and sodium hydroxide, so that the PH value of 12.5-13.0.

5, copper 30min-60min, you can wash into the follow-up treatment.

6, according to the specific requirements, you can make the following choices:

①, black drawing antique.

②, passivation, drying, made of antique copper.

③, plating other metals, such as chemical nickel plating, chemical tin plating.

(E) Matters needing attention: 

The process of operation to wear plastic gloves and protective glasses and have a good exhaust equipment.
