What is electroplating for?

Electroplating refers to electroplating workers, which is a common recruitment position in the electrical industry. Employees need to have technical secondary school education or above, master basic electroplating knowledge and skills, and be able to adapt to overtime.

Its work contents include:

1. Complete the production tasks assigned by the workshop supervisor on time and strictly abide by the company's 6S management.

2. Wear prescribed clothing and protective equipment before formal work to eliminate potential safety hazards at the work site.

3. Before electroplating, check whether the products are in good condition and whether the quantity meets the standards, and record the temperature and time during the processing of parts.

4. Prepare the concentration of chromium plating solution in strict accordance with the company's standards, and regularly check whether the solution ratio meets the standards.

5. Seriously implement the company's rules and regulations, do not operate the equipment in violation of regulations, abide by the saving rules during work, and do not waste water, electricity and production materials.

6. Use vacuum coating machine to finish color matching independently to avoid the generation of defective products.

7, according to the compliance method to deal with waste, to ensure that the environment is not polluted.

principle of operation

Electroplating requires a low-voltage and high-current electroplating bath power supply and an electrolytic device consisting of electroplating solution, plated parts (cathode) and anode. Among them, the composition of electroplating solution varies according to the plating layer, but they all contain a main salt for providing metal ions, a complexing agent for complexing the metal ions in the main salt to form a complex, and a buffer for stabilizing the pH of the solution.

Anode activators and special additives (such as brighteners, grain refiners, leveling agent, wetting agents, stress relievers and fog suppressors). ). Electroplating is a process in which metal ions in plating solution are reduced to metal atoms through electrode reaction under the action of external electric field, and metal deposition is carried out on the cathode. Therefore, this is a metal electrodeposition process including liquid phase mass transfer, electrochemical reaction and electrocrystallization.
