Over 6 Meters' Length Ultra Long Aluminium Honeycomb Panel with
Surface PVDF Powder Coated and Opened Edge
Product Descroption
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.

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.
Application:
(1) building external curtain wall panel
(2) interior decoration works
(3) billboards
(4) ship building
(5) aviation manufacturing industry
(6) indoor partition and commodity display stand
(7) Commercial vehicle and container truck body
(8) bus, train and subway use
(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.
