The way to identify the quality of the surface of the aluminum plate coating is to look at the edge of the aluminum plate to see if the coating can be lifted off. Qualified aluminum plate coating is compounded at high temperature, and it cannot be peeled off. The one that can be peeled off must be glued and cannot be purchased. In addition, many sales will claim that their aluminum plate is covered with imported film. In fact, once the aluminum plate is installed, it is rarely moved. The difference between the so-called imported film and domestic film is not obvious at all. So there is no need to care about whether it is an imported film or not, just take a few samples and compare them in the bright place, and choose a good gloss.
The identification method of the quality of the aluminum plate is very simple: take an aluminum plate and bend it by hand. The bad aluminum plate will be easily bent and will not return to its original shape, while the good aluminum plate will take some time to bend. strength, and after bending, it will rebound to a certain extent, which is the difference in toughness and strength between aluminum materials. A good aluminum plate will not bend or fall in the middle after installation, ensuring stability. The aluminum plates on the market have various thicknesses between 0.5 and 0.8 mm. Many salesmen will boast to you that their own aluminum plates are very thick and very good. In fact, the quality of the aluminum plate is not all in the thickness, as long as the aluminum has good flexibility, 0.6 mm is enough. 0.8mm aluminum plate is generally used for engineering, because the aluminum plate required for tooling is often very long, in order to prevent the middle from falling, thicker is used, and the aluminum plate for home decoration is rarely more than 4 meters, and 0.6 mm is enough. In addition, don’t believe it when the salesman says how thick your aluminum plate is. You can find a vernier caliper to measure it and you will know.
