2. Copper, such as damp in transport, dry with cloth or dry in the sun after stacking

3. The warehouse should be ventilated and 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 rust 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
