Over 6 Meters' Length Ultra Long Aluminium Honeycomb Panel with Surface PVDF Powder Coated and Opened Edge
The powder coating process for the aluminium honeycomb panel includes three steps: pretreatment of the metal structure, powder coating and curing.Removal of oil, dirt, lubrication greases, metal oxides, welding scale etc. is essential prior to the powder coating process. It can be done by a variety of chemical and mechanical methods. The selection of the method depends on the size and the material of the part to be powder coated, the type of impurities to be removed and the performance requirement of the finished product.
Chemical pre-treatments involve the use of phosphates or chromates in submersion or spray application. These often occur in multiple stages and consist of degreasing, etching, de-smutting, various rinses and the final phosphating or chromating of the substrate. The pre-treatment process both cleans and improves bonding of the powder to the metal. Recent additional processes have been developed that avoid the use of chromates, as these can be toxic to the environment. Titanium zirconium and silanes offer similar performance against corrosion and adhesion of the powder.
In many high end applications, the part is electrocoated following the pretreatment process, and subsequent to the powder coating application. This has been particularly useful in automotive and other applications requiring high end performance characteristics.
Another method of preparing the surface prior to coating is known as abrasive blasting or sandblasting and shot blasting. Blast media and blasting abrasives are used to provide surface texturing and preparation, etching, finishing, and degreasing for products made of wood, plastic, or glass. The most important properties to consider are chemical composition and density; particle shape and size; and impact resistance.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
For the edge open solution, as the aluminium honeycomb panel will be used in the downstream production process for change the size such as cutting and carving, it is not necessary to make the edge closed so that the cost and time can saved. Also, for the installation method, there will be supporting frames applied to the aluminium honeycomb panel and after installation, the edge will be covered by the installation frame, it is not necessary to make the edge sealed.
Nowadays, the decoration and renovation industries requires longer panel as the building scale is becoming larger and larger while the lifting machines are capable to do so. The length of the aluminium honeycomb panel have been expected to be more than 6 meters to be suitable for more real application. Pasia is able to produce the length up to customers's requirement.
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.

(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
