Precautions for storage of copper wire materials

1. Copper shall be stored in clean and dry warehouses according to different composition and grades , and shall not be stored with acid, alkali and salt materials

2. If the copper damped in transportation, please drying with cloth or dry in the sunshine before stacking

3. The warehouse should be ventilated. The humidity and temperature in the warehouse should be adjusted. It is generally required that the temperature in the warehouse should be kept at 15~30 ℃ and the relative humidity should be kept at about 40%~80%

4. Electrolytic copper can not be mixed with rubber and other acid-proof materials because of unwashed residual electrolytes.

5. As the copper is soft, it should be avoided to pull, drag or fall, throw, knock or touch when handling and stacking, so as not to damage or injure the surface

6. If corrosion is found, use linen or copper wire brush to wipe off, do not use steel wire brush, in order to avoid scratching the surface. It should not be oiled.

7. For copper wire, no matter the severity of corrosion, in principle, will not carry out rust removal or oiling. If it is contaminated with rust, it can be removed without affecting the wire diameter requirements, and wrapped with moisture-proof paper

8. Serious corrosion, in addition to rust, but also isolated storage, and should not be stored for a long time. If rust cracks are found, they should be removed from the storage immediately
