How much do you know about the performance characteristics of fluorocarbon aluminum panels? What causes the surface to be uneven?
Oct 31,2022
The performance characteristics of fluorocarbon aluminum panels are as follows:
1. This high-quality aluminum alloy panel is processed from aluminum alloy as the base material, thus possessing the strength characteristics of aluminum alloy itself. Common processing thicknesses are 1.5mm, 2mm, 2.5mm, and 3mm. Common specifications are 600mm*60mm and 600mm*1200mm, with sizes reaching up to 8000mm*1800mm. All coating materials are made from high-quality brand paints.
2. A complete fluorocarbon aluminum panel includes a protective film and resin. If three layers are coated, there are three layers: varnish, topcoat, and primer, pretreatment, aluminum plate, and back coating. The coating on the substrate greatly enhances the panel's performance, providing strong resistance to weather conditions such as acid rain and ultraviolet rays. Mineral wool or rock wool can also be added to the back of the panel to provide thermal insulation and soundproofing effects.
3. The panel will be processed into various required shapes according to design requirements before use and coated with the necessary colors, made entirely according to actual requirements, making the construction a relatively simple splicing process. No harmful gases are produced during the processing, and none are generated during use, making it harmless to human health and the environment.
4. Since aluminum panels can be processed into any shape according to design requirements and can be sprayed with various colors as needed, they provide designers with great creative space, unrestricted by shape and color.
Specific reasons for the uneven surface of fluorocarbon aluminum panels:
(1) The working belt length ratio of the extrusion mold or the cavity size is incorrectly designed, leading to severe flow ratio imbalance.
(2) The extrusion mold has obstruction angles and flow promotion angles.
(3) The descent speed of the working belt of the upper and lower molds of the extrusion mold exceeds the standard.
(4) The working belts of the upper and lower molds of the extrusion mold are not parallel and have openings.
(5) The resistance of the upper mold in the extrusion cavity (diversion platform) is too high, blocking the working belt or the drainage channel (size, depth, position) is incorrect.
(6) There is too little or no empty knife on the outside of the working belt of the extrusion mold (poor electric spark laying) or it is too large (working belt cracks and deforms without support).
(7) For new or repaired aluminum panel extrusion molds, the rough sand belt grinding by the mold factory is uneven, resulting in inconsistent smoothness of the mold working belt.
(8) Some aluminum panels are oiled during the extrusion process.
With the continuous advancement of manufacturing technology and material development, fluorocarbon aluminum panels are widely used in more and more other industries, such as shipbuilding, ground transportation, machinery, and architectural decoration. The decoration industry is undoubtedly a major market for aluminum panels.
Due to the characteristics of the sandwich structure of fluorocarbon aluminum panels, they were first applied to aerospace vehicles, ensuring their functionality while significantly reducing the weight of the aerospace vehicles, allowing them to travel longer distances on the same fuel supply.
