Attention to the storage of aluminum coils
Aluminum coil manufacturers: today there are 4 items that we need to pay attention to, in relation to the storage of aluminum coil.
After we buy the aluminum coil, we must remember to place well, this is because in the placement of not in place, it is very simple to let the aluminum coil presents oxidation, so we lost the meaning of the purchase of aluminum coil, so we need to understand the aluminum coil should be placed in what place.
1, the aluminum coil with plastic film wrapped, if the conditions allow, if placed in a desiccant place, so that the air can absorb the moisture, and then avoid the problem of oxidation.
2, if the warehouse leakage of rain, leakage of snow, then should not be placed in the aluminum coil, so that it is very simple to let the oxidation of the situation, this must be borne in mind.
3, if during the placement suddenly from the low temperature region to the high temperature region, then we do not immediately open the package, because this is very simple to present oxidation, we should wait until the aluminum volume applicable after the unsealing, so that the oxidation will not present the situation.
4, if the aluminum volume is placed in the wooden box, then we must ensure that the humidity of the wooden box to be less than 18%, and the temperature of the aluminum volume can not be higher than 45 ℃, these two we do not remember the wrong.
Aluminum rolls can be packaged as a whole, can also be divided into small volumes; aluminum rolls with lined paper core or aluminum core, to prevent deformation of aluminum rolls, or bending by extrusion; aluminum rolls to be sealed with plastic sheeting, sealed with transparent tape to prevent moisture from entering the aluminum rolls corrosion discoloration; outer packaging using thick paper shell packaging tight, can also add a layer of kraft paper between the plastic sheeting and paper shell, the packaging of aluminum rolls placed on the wooden tray, and steel tape Reinforcement. Especially the export of aluminum rolls in the packaging and then wrapped with multiple layers of winding film can effectively avoid the entry of water vapor, transportation and storage to prevent rain.
