Do you know the difference between aluminum sheet and aluminum composite panels acp sheet? Aluminum sheet is a construction and decoration material formed by processing pure metal aluminum sheet after chroming and other treatments and then using fluorocarbon spraying technology. Aluminum composite panel is a composite material formed by chemically treated painted aluminum sheet as the surface material and polyethylene plastic as the core material, which is processed on special aluminum composite panel production equipment. So, what is the difference between aluminum and aluminum composite panel?
1、Material and price
Aluminum plate is generally 2-4mm thick AA1100 pure aluminum plate or AA3003 aluminum alloy plate, the domestic general use of 2.5mm thick AA3003 aluminum alloy plate; aluminum plastic plate is generally 3-4mm three-layer structure, including the upper and lower two 0.5mm sandwiched PVC or PE. we can see from the material, the cost of aluminum plastic plate is certainly much lower than the aluminum veneer.
At present, the domestic aluminum plate mainly uses fluorocarbon spraying aluminum plate, the processing process includes sheet metal parts processing and spraying, sheet metal processing mainly through the flat plate after cutting, folding, bending, welding, grinding and other processes, the aluminum plate processing into the shape and size required for construction; spraying is spraying paint on the processed sheet metal, one is manual spraying, one is machine spraying. Machine spraying is generally only suitable for regular flat panels, and one of the major advantages of manual spraying is that the color can be optional regardless of the size of the volume.
The processing of aluminum composite panel is more complicated than that of aluminum panel, mainly there are four major processes: chemical formation, painting, compounding and trimming, which are all automated except for trimming. From its processing process can be seen, aluminum composite panel in environmental protection and safety occupies a certain degree of superiority. Coupled with the simplicity of the sheet metal plus process of aluminum, some private workshops also began to get involved, which seriously affects the stability of the quality of the aluminum plate market.
The appearance of aluminum sheet is a little worse than aluminum composite panel, but its mechanical properties are obviously better than aluminum composite panel, and its wind pressure resistance is also better than aluminum composite panel.
Fire characteristics aluminum plate is not combustible, the early aluminum plastic plate is not able to fire but with the development of aluminum plastic plate technology forward, now the production of fire-resistant aluminum composite plate due to the addition of non-toxic flame retardant materials in its PE, fire performance greatly improved, has been fully able to meet the needs of engineering fire. Residual value aluminum plate has a certain residual value, but due to its expensive cost, compared to almost no residual value of aluminum composite plate, the waste caused is still much larger.
The above is a summary of the difference between aluminum and aluminum veneer, comprehensive analysis of the above, aluminum and aluminum composite panels have their own merits, there is no substitute. Two kinds of plates have their own characteristics, in the end to use which, it can be based on the actual situation, if the need for irregular shape, the need for a variety of colors, the need to resist the relatively strong environment, then you should choose aluminum veneer, on the contrary, the use of aluminum composite panel is enough.
