Product Description

Chemical bottom layer nickel

Electroless nickel plating additive for PL-7 plastic electroplating

1. Description

PL-7 chemical plating of nickel additive can be activated on a good plastic surface, depositing a layer of a smooth, continuous, good adhesion of the nickel layer, deposition speed not only nickel, but also to be able to establish contact with the contact for the plating around point. PL-7 has good process stability, simple operation and maintenance . Suitable for plastic and various metal substrates, such as aluminum, steel, copper and their alloys.

2. Features and uses

1. This process can deposit a smooth and uniform thin nickel layer with good adhesion on the surface of the activated plastic;

2. Low-temperature type chemical nickel, which can be plated quickly without missing plating, and can be used for a long time without changing the tank;

3. Good stability, long service life and low cost;

3. Solution composition and operating conditions

4. Solution preparation

1. Before the new tank is equipped, soak it with 10% volume ratio ammonia water for 24 hours, and keep the temperature at 49 degrees, and then use pure water to clean it thoroughly.

2. Pour about 2/3 of the required volume of distilled water (deionized water) into the plating tank ;

2. was added with stirring PL. 7A- , stirred uniformly, added PL-7B , stirring was continued uniformly;

3. Adjust the pH to 8.5 with analytical pure ammonia water (about 20-25ml/L);

4. Dilute with pure water to the required volume;

5. Stir until completely dissolved evenly.

5. Tank liquid control and maintenance

1. the metallic nickel content measured by chemical analysis of complement: PL-7 C content is not analyzed, by adding 10ml of each of the PL-7 B while adding 10ml of PL-7 Example C supplement.

2. determined daily nickel content , with PL. 7- B / C also added, maintaining the solution process range.

3. the daily measured values and adjust the PH.

4. if a long shutdown, when the cut-nickel and PL-7 concentration B / C is maintained at the optimum value . 8 0%, and adding 10-20ml / L of PL-7 stabilizer. When activated, add PL-7 B and PL-7 C to the best value and adjust the PH value to 8.5.

5. solution purification: new solution is filtered with at least eight hours per day; month after continuous filtration for use.

6. the plating tank cleaning: shutdown time or when there is found to take gas, the solution must be removed weekly plating tank, the plating tank for cleaning as follows: 1) washing with water the plating tank; 2) with 1: 1 nitric acid plating tank wall The nickel layer on the surface is removed; 3) clean the plating tank with clean water; 4) clean with pure water; 5) filter the solution back to the tank.

7. when the surface of the bath was found a large number of bubbles emerge indicating that there is no bath stability, it is necessary to add PL-7 stabilizer 10-15ml / L improve the stability of the bath is adjusted.


6. Safety warning

For the sake of health and safety, Bigley recommends that manufacturers refer to Bigley's material safety data sheet before use .

7. Wastewater treatment

Before adopting the sewage treatment method provided by Bigley , the user must follow the pollution discharge law allowed by the local government. If there is any conflict with the company's proposal, the local law shall be the basis .
