Crystallization copper mould tubes have good and thermal conductivity but are easily oxidized in air.
The use of antioxidants, also known as copper antioxidants, improves the discoloration and antioxidant resistance of the crystallizer copper tube. Form passivation film on its surface to prevent surface dark and improve corrosion resistance, discoloration, and oxidation resistance. And does not affect the welding performance. In particular, crystallizer copper tubes were used for passivation after grinding. The number of antioxidants used in the raw fluid can be used directly. Antiantioxidant protector is the last antioxidant process in copper polishing. During use, the workpiece should be soaked in the drugs and shaken slightly so that the workpiece can have full contact with the drug. Antioxidants have no irritating odor, simple operation, and high production efficiency.
However, after the work parts are treated with pharmaceutical liquid, they must be cleaned with clear water or pure water, otherwise, the work surface will be affected.
The anti-oxidation technical process of crystallizer copper pipe is: deoil → washing 2 → grinding or sulfuric acid activation 10% → washing 2 → anti-oxidation treatment → washing 2 → drying.
