White corundum for sand blasting and electroplating on copper surface
White corundum has high hardness, and the sandblasting process removes the plating layer and impurities on the copper surface.
The particles of white corundum are uniform, and the copper surface after sandblasting is fine and uniform, making it easy to obtain ideal surface roughness and cleanliness.
White corundum sandblasting has low calorific value, high efficiency, and isn’t prone to failure due to high temperature or chemical corrosion, ensuring the stability and reliability of the sandblasting process.
White corundum can be recycled repeatedly, which reduces production costs and improves economic benefits.
Application of white aluminum oxide in sandblasting and deplating of copper surfaces
Surface repair: Before electroplating, white corundum sandblasting provides a clean and rough workpiece for electroplating.
De-plating: Adjusting sandblasting process parameters, such as pressure, distance and time, can achieve the precise effect of white corundum on the electroplating layer.
Follow-up treatment: After sandblasting, clean the copper parts thoroughly to remove residual sand and complete.
Precautions for sand blasting and electroplating of white corundum on copper surface,
1. Select appropriate sandblasting process parameters, including sandblasting pressure, distance and time, etc. 2. Make reasonable adjustments according to factors such as the material, thickness and surface requirements of the copper parts to achieve the best effect.
In summary, white corundum has significant and efficient advantages in the sandblasting and deplating process of copper surfaces. It can clean and roughen the copper surface, laying a good foundation for subsequent processing or painting.
