Aluminum plate features and installation precautions

【China Aluminum Industry Network】Aluminum plastic panel is a kind of indoor and outdoor decoration materials that have just emerged in China. At present, there are many brands on the market, and there are many mixed products, and the quality of products is uneven. Because of its special structure, consumers are generally more difficult. To identify the intrinsic quality of products, we have a responsibility to remind consumers to pay attention to the following identification methods when purchasing and using aluminum-plastic composite panels: 1) Look at whether the aluminum-plastic panel is smooth and smooth, free of ripples, blisters, splashes, and scratches. 2) Measure whether the aluminum plastic board meets the international requirements, the inner wall board 3mm, the outer wall board 4mm. 3) Fold off the corner of the aluminum-plastic panel. It is not the PE material that is easily broken or it is doped to make false. 4) The middle material of the aluminum-plastic composite plate is burned, and the true PE is completely burned. Doping causes false combustion and impurities. 5) When the router is bent, see if the front is broken. 6) Dimethylbutanone discriminate the fluorocarbon coating on the outer wall board. Dimethylbenzene is used to identify the inner wallboard coating. After 5 minutes, the reagent is wiped off to see if the bottom is exposed. [Installation Precautions]: 1)Protective performance of the protective film The protective film consists of black and white double polyethylene. During the installation process, do not remove the protective film to protect the board surface from being scratched or stuck to the mud. Under normal climatic conditions, the protective film is torn off within six months without any transfer of glue and other damage to the board. Of course it is better to tear off the protective film after construction. 2) The direction of the coating will cause slight color difference. When installing the aluminum-plastic plate with metal color, flash color, and stone grain series, be sure to install it according to the direction of the mark on the protective film. Otherwise, color difference may occur due to inconsistent installation directions. 3) Difference in gloss caused by plasticizer Do not paste PVC tape, polyurethane sealant, and modified silica gel on the protective film of aluminum plate, because the plasticizer contained in these materials will penetrate the protective film. Causes changes in the gloss of the coating.
