How to deal with oxidation resistance of mould copper tube
Mould copper 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, can improve the anti-discoloration and anti-oxidation ability of the copper tube of the crystallizer. The passivation film is formed on the surface to prevent the surface from darkening, and improve its anti-corrosion, anti-discoloration, anti-oxidation ability, and does not affect the welding performance. In particular, the mould copper tube is passivated after polishing. The amount of anti-oxidant can be used directly. Anti-oxidation protective agent is the last anti-oxidation process in the copper polishing process. During the use, the workpiece should be immersed in the reagent and shaken slightly so that the workpiece can fully contact with the reagent. Oxidation protection agent has no irritating smell, simple operation and high production efficiency. However, after the workpiece is treated with liquid medicine, the surface must be cleaned with water or pure water. Otherwise, the workpiece surface will be affected.
