Зеркальное меднение Кислый электролит с унитиолом

Introduction

This tutorial will guide you through the process of mirror copper plating using an acidic electrolyte with unithiol, as demonstrated in the video. This method is popular for achieving a smooth and reflective copper finish on various items. Understanding the steps and safety precautions involved will help you successfully replicate this technique.

Step 1: Prepare the Workspace and Materials

• Gather Materials: You will need:

  • Copper sulfate
  • Unithiol (a chemical used to enhance plating)
  • Distilled water
  • A container for the electrolyte solution
  • A power supply (DC power source)
  • Copper anode
  • The item to be plated
  • Safety gear (gloves, goggles, apron)

• Set Up Workspace: Ensure your workspace is well-ventilated and free from clutter. Lay down protective coverings to avoid spills.

Step 2: Create the Electrolyte Solution

• Mix the Solution:

  • In a container, mix the following:
    • 100g of copper sulfate
    • 10g of unithiol
    • 1 liter of distilled water
  • Stir the mixture until all solids are dissolved.

• Check pH Level: Use pH test strips to ensure the solution is acidic. Adjust if necessary.

Step 3: Prepare the Item for Plating

• Clean the Surface:

  • Thoroughly clean the item you want to plate. This may involve sanding or using a degreaser to remove any oils or residues.

• Rinse and Dry: Rinse the item with distilled water and let it dry completely to ensure good adhesion of the copper.

Step 4: Set Up the Plating Circuit

• Connect the Power Supply:

  • Attach the positive lead to the copper anode and the negative lead to the item being plated.

• Immerse in Electrolyte: Carefully submerge both the anode and the item in the electrolyte solution, ensuring they do not touch each other.

Step 5: Electroplating Process

• Adjust Current: Set the power supply to a low current (typically around 0.5 to 2 amps) to start the plating process.

• Monitor the Process: Keep an eye on the plating. You should see a gradual buildup of copper on the item. The duration may vary depending on the desired thickness of the copper layer.

• Check Regularly: Inspect the item every few minutes to ensure even coverage and adjust the current if necessary.

Step 6: Finish the Plating

• Remove and Rinse: After plating for the desired time, turn off the power supply, remove the item from the solution, and rinse it with distilled water to remove any residual electrolyte.

• Dry the Item: Use a soft cloth to dry the item thoroughly.

• Polish for Shine: For a mirror finish, polish the item with a suitable metal polish or buffing compound.

Conclusion

You have now successfully completed the process of mirror copper plating using an acidic electrolyte with unithiol. Remember to follow safety guidelines throughout the process and ensure proper disposal of any chemicals used. Experiment with different items and plating times to achieve your desired results.
