PVDF Powder Coated Aluminium Honeycomb Panel with Edge RHS Sealed for Facade Building
Product Description
The PVDF material used for the aluminum honeycomb panel is to make the panel with a luxurious but rigid and anti-corrosion surface. The Powder Coating process will be versatile on outdoor building decoration products. The powder coating process will make the aluminum surface more artistic and nice looking. The PVDF powder coated aluminum honeycomb panel has been widely used as wall panel, partition panel and so on. The weight is comparatively lighter than the same thickness FRP solid panel but with a similar strength with the FRP material. The RHS (Rectangular Hollow Section) is also in aluminum alloy which possesses the same properties to the aluminum honeycomb surface plates and cores. So the expanding and contraction are the same which makes the whole panel as a complete one.
General Description
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.
Features
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.

(9)With strict environmental requirements of the modern furniture industry, aluminum honeycomb panel is an ideal material to produce furniture. Depending on Its completely non-toxic green quality, it is not necessary for the furniture manufacturers to process environmental procedures. In addition, the surface veneer for aluminum honeycomb panels can be diversified such as solid wood, aluminum, gypsum board, natural marble etc
(10) aluminum honeycomb panel partition: the emergence of aluminum honeycomb panel partition breaks the traditional partition mode, with a noble and fresh style.
