Nickel plating manufacturer Metal nickel plating Bright electroless nickel plating

Environmentally friendly chemical nickel-plated liquid

First, the product code: Q / YS.602 (Yi Shun brand)

Second, product features:

The chemical nickel-plated water is suitable for iron, steel, zinc alloy, zinc-treated aluminum alloy and copper alloy surface nickel-plated alloy layer. This product is non-toxic, environmentally friendly. No plating equipment, just thermostat plating. Is a bright nickel-phosphorus alloy layer, excellent corrosion resistance, excellent adhesion Strong bath stability, life expectancy of more than 12 cycles This product is not only suitable for metal surface nickel (such as: iron, stainless steel, aluminum, copper, etc. Etc.), the same applies to non-metallic nickel plating, and does not require expensive palladium palladium low cost such as: ceramic nickel, glass nickel, diamond nickel, carbon nickel, plastic nickel, resin nickel and so on. Bath maintenance is simple, low cost, does not require plating equipment. (Note: "Phosphorus content of 7% -11%)

Third, the product composition:

Products A, B, C three agents, A and B ratio of 1: 2 to open the cylinder, with a ratio of 1: 1 and C added as an intermediate supplement.

Fourth, open cylinder preparation and use of agents:

① A and B agent with water with the match, with the ratio of A: B: water = 1: 2: 7.

② with pure water to clean the plating tank, and then added to the tank half the size of pure water tank.

③ first B agent proportionally added to the tank Stir, while stirring slowly add A agent.

④ 10% ammonia water to adjust the PH value to 4.7 ± 0.2.

⑤ add deionized water to the specified volume.

⑥ heating bath bath temperature stable at 90 ℃ ± 3 ℃.

Fifth, the operation process:

① pre-treatment: Pre-treatment of the coating quality is essential, to make the surface of the workpiece before plating no pollution, and is in an activated state, this process are: degreasing, rust, polishing, washing.

② pickling activation: pickling activator soak the workpiece with 2-3 minutes, and then washed.

③ rinse the workpiece with hot deionized water, the workpiece temperature, in order to avoid the next plating, the cold workpiece cooling bath to absorb heat and lead to stop plating.

④ in accordance with 0.5-1.5dm2 / liter loading than hanging suspension in the bath, bath temperature control at 90 ℃ ± 3 ℃, the use of time> 5 minutes, depending on the thickness may be.

⑤ plating process should be mild light mixing, the temperature and bath evenly distributed, so as to ensure the stability of chemical nickel plating, and the consistency of the coating at the same time, the bath should be recycled filter mesh: aperture 1-8 Micron, resistant to 100 degrees Celsius, acid.

⑥ nickel plated with hot water to be completed, if necessary, can be passivated.

Sixth, the maintenance of chemical nickel plating:

① in the plating process, because of the constant consumption of ingredients, plating speed will slow down, according to the number of bubbles to add supplements A and C, according to A: C = 1: 1 added. A small amount of time to make up for every consumption of one gram of nickel metal, need to add A and C of 10 ml each. When a large number of supplements A and C, the first cooling stop, then add A, C supplements and stir, in order to carry out nickel plating.

② plating process, the bath pH value will change, the fresh bath pH control in 4.7-4.8, with the bath aging, PH value will slowly rise.

③ for the copper and nickel alloy surface to use clean wire or aluminum wire and copper parts in contact with the lead.

④ plating process to the bath often analysis test: PH value and nickel ion content.

Nickel detection method: Take 5.00ml plating solution into a 500ml flask, add 100ml of deionized water, then add 100ml of ammonia, add carbamate indicator. With 0.05mol / L of EDTA titration from orange to purple as the end point, the volume of milliliters consumed EDTA is recorded as V.

Formula: Nickel (g / L) = 0.587 * V

⑤ pre-chemical nickel plating to undergo rigorous pre-treatment, to ensure that the workpiece surface in a clean and active state.

⑥ regular testing equipment: automatic temperature control system, circulating filtration system, timely detection and timely exclusion.

⑦  bath loading ratio to be controlled at 0.5d㎡ -1.5d㎡.
