Anti Oxidation Treatment Of Copper Mould Tube
Copper mold tube has good thermal conductivity and other physical properties, but it is easy to oxidize in air. The use of anti oxidant, also known as copper anti oxidant, after treatment, can improve the anti discoloration and anti-oxidation ability of the copper mold tube. A passivation film is formed on the surface to prevent the surface from darkening, and improve its anti-corrosion, anti discoloration and anti-oxidation ability. And does not affect the welding performance. In particular, the copper mold tube is used for passivation treatment after polishing. The stock solution with the amount of antioxidant can be used directly. The use temperature is 20-50 ℃ and the time is 3-5 minutes. The anti-oxidation protective agent is the last anti-oxidation process in the copper polishing process. During use, the workpiece should be soaked in the agent and shaken slightly so that the workpiece can fully contact the agent. The anti-oxidation protective agent has no pungent smell, simple operation and high production efficiency. However, after the workpiece is treated with liquid medicine, the surface must be cleaned with clean water or pure water, otherwise it will affect the workpiece surface.
The anti-oxidation process flow of copper mould tube is as follows: oil removal → water washing twice → polishing or 10% sulfuric acid activation → water washing twice → anti-oxidation treatment → water washing twice → drying
