Polyester Powder Coated Aluminium Honeycomb Roof Panel with Edge Exposed Building Top
Polyester Powder Coated Aluminium Honeycomb Roof Panel with Edge Exposed Building Top is an aluminum honeycomb panel with its top surface powder coated with a polyester (PE) coating but the edges are left open without any sealing to them. The product is widely used on the modern building top roof as it can achieve various shapes of the panel as well as the roof shapes diversity. The PE powder material is comparatively lower in price against its competitor PVDF powder. Without the edge sealing, the panel can be much lower in price too. For large scale building envelope including the roof, the PE coating and edge open can both save lots of money.
1. Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate (PET).
2. Polyesters include naturally occurring chemicals, such as in the cutin of plant cuticles, as well as synthetics through step-growth polymerization such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not.
3. Depending on the chemical structure, polyester can be a thermoplastic or thermoset, there are also polyester resins cured by hardeners; however, the most common polyesters are thermoplastics.
Aluminum honeycomb panel is a bonded sandwich structure system of two surface aluminium plates and one honeycomb cores with a special purpose adhesive. Industrial used aluminium honeycomb panel will add some more processes such as surface treatment, edging, embedding, carving and so on to make the panel suitable for special conditions. It has been widely used by the industries of civil construction, transportation, exhibition, signage, elevator, clean room etc. The honeycomb technology is from aerospace technology. The whole production process is finished in the modern factory, using hot pressing or vacuum pressing technology. Due to the high thermal conductivity between the aluminum plates and honeycomb, it is synchronized the thermal expansion and contraction of the inside and outside aluminium material. There are small holes on the honeycomb core foil wall so that the air is free of flowing inside the panel box. Furthermore, sliding mounting buckle system does not cause structural deformation during thermal expansion and contraction.
The center material is aluminum hexagonal honeycomb with a small density (about 3 to 7 kg per square meter), about 1/5 of the weight of wood with the same area and thickness, 1/6 of the glass, 1/7 of solid aluminium, which greatly reduced the building load and construction cost. Thanks to the air contained in the core, the panel can be sound and thermal insulated. Because of no combustible material contained, the fire rating can be at least B1 level. The panel performs well also on waterproof, moisture-proof, no harmful gas release, with a high unit mass of the specific strength and stiffness, not easy to deformation, completely overcoming the collapse and deformation in the center area if with large panel. The panel edge can be cut depending on real conditions. The PVDF coating can guarantee the product life more than 30 years.
After surface treated with corrosion resistant fluorocarbon resin, it can be widely used on curtain wall, roof, large façade, signs and interior decoration. The front plate of the aluminum honeycomb panel is painted with E. C. C. A. quality standards PVDF fluorocarbon paint with ordinary color or metallic color, so the surface has excellent weather resistance.
In case of heavy rain, there is particularly large noise when the raindrops hit the aluminum veneer or aluminum-plastic panel, while honeycomb panel can avoid this situation. Aluminum honeycomb panels are generally made of fluorocarbon coated aluminum plates. The continuous roller coating with PVDF material is the most important point to avoid color difference and flat coating film. Based on this, it can keep the exterior building with bright color for long time.
