How to prevent oxidation of mould copper tube

Copper mold tube has good thermal conductivity and thermal conductivity, but it is easy to oxidize in air. The use of antioxidants, also known as copper antioxidants, can improve the discoloration resistance and oxidation resistance of mold copper tubes. A passive film is formed on the surface to prevent the surface from darkening and improve the corrosion resistance, discoloration and oxidation resistance. And does not affect the welding performance. In particular, the mold copper pipe is used for passivation after grinding. The stock solution with the amount of antioxidant can be used directly. Antioxidant protector is the last antioxidant process in copper polishing. During use, the workpiece should be immersed in the drug and shaken slightly so that the workpiece can fully contact the drug. The antioxidant has no pungent smell, simple operation and high production efficiency. However, after the workpiece is treated with liquid medicine, it must be cleaned with clean water or pure water, otherwise it will affect the surface of the workpiece.

The anti-oxidation technical process of crystallizer copper pipe is: degreasing → washing twice → grinding or sulfuric acid activation 10% → washing twice → anti-oxidation treatment → washing twice → drying.
