How long is the warranty period of the aluminum alloy sheet is closely related to the scope of its application. For example, the aluminum coil used in construction sites has a long warranty period. Generally, if the aluminum alloy sheet stored in the warehouse is not opened, the warehouse will It is cool and ventilated, and it will not be a problem to store it for a long time. The key point is to keep it away from water. If it is an unpacked aluminium alloy plate, it is recommended not to store it for a long time, because it is inevitable that there will be moisture intrusion, and the rainy season in the south is abundant, so be careful.
The aluminum alloy panels should be stored in a cool, ventilated and dry warehouse after being packaged. They should be stacked neatly when stacked, and the number of stacked layers should not be too high. Because the material of the aluminium alloy plate is relatively soft, so as not to be deformed or injured by the packing belt under the heavy pressure. It is not suitable to use steel wire rope when lifting and transporting. If the aluminium alloy plate is too thin, it is easy to be cracked and deformed by the four sides of the steel wire rope. A cloth hanging rope with a large stress area can be used. For steel wire ropes, four sides can be suspended in parallel. Lift the special hook for hoisting. The aluminum alloy panels should be stored in a cool, ventilated and dry warehouse after being packaged. They should be stacked neatly when stacked, and the number of stacked layers should not be too high.
During construction, aluminum alloy panels need to be waterproof and moisture-proof in this season, and there is a lot of autumn rain. If the aluminium alloy plate is not placed in a dry warehouse, once it rains, the acid in the rain will cause the aluminium alloy plate to oxidize. The hot aluminium alloy plate is basically oxidized scrap aluminum, which is a big loss for the construction party. Therefore, it is necessary for you to understand the precautions for the storage of aluminum alloy sheets:
1. Wrap the aluminium alloy plate with plastic film, and place it in a place with desiccant if conditions permit to absorb moisture in the air and avoid oxidation problems.
2. If we suddenly change from low temperature area to high temperature area during placement, we should not open the package immediately because it is easy to oxidize. We should wait until the aluminum alloy sheet can be unpacked so that oxidation does not occur.
3. If the aluminium alloy plate is placed in a wooden box, it should be ensured that the humidity of the wooden box is less than 18%, and the temperature of the aluminium alloy plate should not be higher than 45 ℃. Make no mistake.
4. If there is rain and snow leakage in the warehouse, aluminium alloy plates should not be placed, which can easily lead to oxidation. This must be kept in mind.
