Orange aluminum composite panels are composite building decorative materials composed of aluminum-magnesium alloy panels, a polyethylene core, and a protective coating. The panels achieve their orange hue through a nano-scale spray coating process, and the core layer utilizes polymer bonding technology to achieve metal-plastic interfacial fusion. Coating systems include PVDF fluorocarbon coating and PE polyester coating, depending on the operating environment. Panel thickness directly affects flexural stiffness and flatness.
Construction Precautions
1. During the surface preparation phase, the concrete matrix moisture content must be controlled within a safe threshold, and metal studs must be cathodically treated for corrosion. The spacing of embedded components should be determined based on wind load calculations, and irregularly shaped curved surfaces require three-dimensional lofting and template preparation for positioning.
2. During the installation phase of the Orange aluminum composite panels, horizontal joints should be staggered to avoid stress concentration, and the allowance for expansion joints should be calculated based on the temperature gradient. The torque applied to the fixing screws must be constant. Overtightening will cause panel deformation, while over-loosening will cause wind vibration and noise.
3. Sharp bends require pre-treating the inner panel using a grooving machine. The minimum radius of curvature of curved sections is strongly correlated with the thickness. The edges of the hollow pattern need to be sealed with glue to prevent the core material from being exposed.
Maintenance Methods
1. Rinse quarterly with a neutral detergent. Avoid using strong acids or alkalis on stubborn stains. Spray a fluorine-based curing agent on the PVDF coating surface every specified period.
2. Scratches less than or equal to the thickness of the aluminum layer can be filled with a special repair paste; penetrating damage requires replacement of the entire panel. Do not hammer to correct dents on the panel surface.
How to maintain the long-lasting orange color in high-UV regions?
PVDF-coated models must be selected. Apply a UV blocker after installing the orange aluminum composite panel. Avoid large, continuous south-facing areas and design sunshades to reduce the duration of direct sunlight.
