Wrap the aluminum alloy plate in plastic and then fold it away. Insulating aluminum skins should not be placed on the roofs of workshops and warehouses where rainwater leaks to ensure that they are kept in a dry environment. Normally, the aluminum skin will be packed in a waterproof package with moisture repellent, so users are advised not to compromise the packing method. The packaging is suitable for long-term storage and use.
The quality of aluminum alloy plates can be distinguished by appearance, flatness and thickness tolerances. High quality aluminum surface without oil, color difference and scratch. This can be distinguished by the appearance of the purchased aluminum skin, so it is recommended that users with no experience in purchasing aluminum skin can distinguish the quality of the aluminum skin by the simplest surface, choosing a high quality aluminum skin or flattening the aluminum skin. On the ground, you can see if the aluminum skin has undulating waves. High quality aluminum skin has been corrected without noticeable corrugations. The thickness needs to be measured using a professional micrometer. After completing the above steps, you can choose the quality aluminum skin.
Aluminum alloy plate processing parts in the process of pretreatment, there are also a lot of need to pay attention to. The natural oxide film on the surface of finely machined parts, which forms only initially and is easy to remove, is oily and heavy in and around the machined surface. If the surface is washed directly with alkali, not only can not be removed, but also the surface after fine processing can not withstand long-term strong alkali corrosion. This will affect the surface roughness, and may end up as waste.
Aluminum plate is a rectangular plate made of aluminum ingots or aluminum rolling after certain processing. Aluminum alloy plate can be said to be the upgraded version of aluminum plate. Various alloying elements are added in the process of aluminum plate processing to improve the mechanical and chemical properties of aluminum plate.
