The aluminum composite panel is a new type of metal-plastic composite material composed by coating aluminum sheet with plastic core material through hot pressing and composited with polymer adhesive film (or hot melt adhesive). It is widely used in interior and exterior decoration, lobby, meeting rooms and other decorative works due to its fire, acid resistance, impact resistance, bendable can nail planning, simple construction, easy to clean, strong wind resistance, flexural strength, good sound and heat insulation performance, which is favored by architectural and decoration industries. ACP panel is a new decorative material very popular among consumers. However, there are some fake and shoddy products in the current market, so as an ordinary consumer, how to know whether the aluminium composite panel is good or bad? Here are some easy ways to help consumers to make a preliminary identification.
Observe the shape
The size of aluminum composite panels should be standardized and neat, which have uniform thickness, smooth surface and straight plate. The product cannot stand when placing the board on the ground, lift the board to weigh, it should not be too soft. Tear up the protective film on the surface of the product to observe, the paint should be clean, no color, spots or scars, uneven gloss, which doesn't have paint leakage and other surface defects. See the thickness According to the national standards, the thickness of the exterior wall panels should be 4 mm and the thickness of aluminum panels should be 0.5 mm; the interior plate thickness is 3 mm and the aluminum plate should be 0.2 mm in thickness; exterior wall aluminum plate is significantly harder than the interior wall aluminum panel.
Carry out comprehensive quality identification in accordance with national standards
Because the price for the main raw material of the aluminum composite panels is certain, coupled with equipment depreciation, labor management costs as well as the production profits, the price has a certain bottom line. Currently, the production profits of aluminum composite panels have almost dropped to the lowest, the obviously too low price is the most significant feature for fake and shoddy products. Of course, it is not enough to rely solely on simple identification if you want to strictly determine the quality of the acp panels. The State issued the ACP Panel national standards for this purpose (GB/T17748-1999). If necessary, consumers should go to the quality inspection departments authorized by the State to carry out comprehensive quality identification in accordance with national standards.
It is best to buy brand products from well-known manufacturers
Industry experts believe that the large number of acp panel applications can change city building's "gray head and gray face" and monotony appearances over the years, but domestic ACP panel enterprises are mixed, individual enterprises still remain in the production stage of small family workshops, some unscrupulous manufacturers shoddy, it is difficult to guarantee the quality of products. Thus, the experts recommended that it is best to buy brand products from well-known manufacturers in order to avoid the hidden dangers for construction work.
