Aluminum Aluminio Gofrado Aluminum for Pre-Insulated Insulated Panel Ductwork

1.Structure of Aluminum Aluminio Gofrado Aluminum for Pre-Insulated Insulated Panel Ductwork

Air ductwork supply is pre-insulated aluminum panels constructed of both aluminum and Poly-isocyanurate. The sandwich panels are comprised of expanded Poly-isocyanurate rigid foam board, faced on both sides by aluminum foil.Ducting is the key part of any central air-conditioning system. It is similar in function to the arteries and veins in the human body as it helps in regulating the temperature in a building. The material used for making ducts for air-conditioning is constantly evolving in order to satisfy the demand for higher thermal efficiency, eco-friendliness, and increased energy savings. Many different materials and systems such as magnetite composite, PVC and so on have been developed as alternatives to the galvanized sheet metal used traditionally. But pre-insulated ducting materials is by far the most popular ducting system in use today. It is essentially a panel made with an insulating material such as PIR (Polyisocyanurate), PUR (Polyurethane) or Phenolic foam material sandwiched in between two layers of aluminium foil. Such a foam panel is easier than traditional galvanized sheet metal to manipulate for complex designs and lighter than its predecessors for installation. These qualities in addition to the fact that it has a much higher thermal efficiency than galvanized sheet metal make it an ideal material for fabricating Airconditioning ducts in harsh climates like the Gulf. Its application has been gradually extended to every type of air distribution system: industrial and commercial. 

For construction of air ducting in HVAC systems, the Polyisocyanurate (PIR), PUR (Polyurethane) and/or Phenolic foam panel with 45kg/m3 density, coated with 80/80µm thick embossed aluminum foil have two panel types:

The air ducts fabricated using ALU 80/80 panels can be installed in plants:

with air speed up to 15m/s

with pressure up to 1000Pa

indoor

The air ducts fabricated by using ALU 80/200 panels can be installed in plants:

with air speed up to 35m/s

with pressure 1750Pa

outdoor

Q:What is the use of aluminum foil?
In European and American countries, foil products for packaging 70% of total demand. In the Chinese market, aluminum foil is mainly used as industrial raw materials, manufacturing, packaging, aluminum foil only 30% of total domestic demand. Although aluminum foil packaging development late, but the market is growing rapidly, the prospects attention.
Q:Does the aluminium tin foil poisionous?
the aluminium paper are more poisionous when heating. The tin paper is poisonousless.
Q:Aluminum corrosion resistance is mainly reflected in what areas?
The second is resistant to salt spray corrosion test conditions generally in the 35 oC, 3% salt spray environment requires 500 hours can not have spots of corrosion. Salt spray corrosion resistance is directly related to the heat transfer sheet length of life. In coastal areas, due to the high salt content in the air, so the heat transfer sheet of salt spray corrosion resistance have high requirements;
Q:The thickness of aluminum foil bag is 30 silks. Is it thick or thin?
It's very thick. What's more, 30 silks should be the thickness of two sides with each side shares 15 silks.
Q:What are the functions of vacuum bag and aluminum foil bag?
Aluminum foil bag usually refers to aluminum-plastic composite vacuum bag, suitable for moisture-proof and light-proof vacuum packaging of large-scale precise machinery and equipment, chemical raw materials and pharmaceutical intermediates. With four-layer structure, it is characterized by good water-proofness and oxygen isolation. Aluminum foil bag can be made into flat pocket style, three-dimensional bags, organ bags, etc, according to the requirements of customers. The test results of GB and ASTM show that the product complies with environmental requirements (a third party testing report available if required) and the environmental standard of EU and North America in which packing material is most strictly required.
Q:Is aluminum tape toxic?
As for aluminum tape, it is nontoxic and the aluminum foil can resist high temperature of 300℃ and most tapes can resist temperature of 180℃. Since aluminum is a good conductor of heat, wrapping the tape with aluminum foil does quicken the heat loss instead of heat preservation.
Q:How does the aluminum foil's moisture resistivity and corrosion resistance?
It has good moisture resistivity and corrosion resistance, and it has thermal conductivity.it has good heat dissipation and UV resistance. The aluminum foil has good acid-resistance and electric conduction
Q:How to prevent aluminum foil from wrinkling?
Due to the strip shape is serious bad, folding formed in the process of aluminum foil coiling or expanding. Its essence is that its tension is not enough to make the box surface flattening. For a device with the tension of 20 mpa, the box surface flatness shall not be greater than 301. When it is more than 301, it will wrinkle inevitably. Due to the rolling aluminum box often bear the bigger tension than follow-up processing, some aluminum foil that just show the bad strip shape when rolling turn to wrinkle when cutting or used after annealing. Main reasons of wrinkling are due to poor flatness controlling, including incorrect roll grinding ,unreasonable roll shape controlling, unreasonable parameter controlling of rolling and cutting process, bad incoming material strip shape and incorrect strip shape adjusting and imperfect precision of sleeve or tube core. Main reasons of wrinkles: The large amount of pressure make the rolling uneven or coiling lack tension. Improper controlling of roll shape or rolling pressure is too low; Uneven thickness of billet, bad flatness or shear wave. Winding shaft precision is not good and the sleeve is not round. Improper control of pressing roller pressure.
Q:How to ues aluminum foil container?
High-grade quality disposable foil container aluminum foil, mainly used in business package, air catering, bread or cake takeout tray and the like. Disposable aluminum foil food box, aluminum foil containers, aluminum foil meal boxes look crisp, easy to use, safe, sanitary, no smell, no leakage. Heating directly in the original packaging and aluminum case with good thermal conductivity and uniform heating effect, it can be widely used ovens, steam boxes, etc.
Q:Is the environmental friendly aluminium foil box poisonous
The product heavy is light, and the product is qualified for the National food hygiene standards.it is convenient for recycle and no harmful substance is produced when processing and no pollution.the aluminium food box is widely used in the flight food and cake with the charateristic of quick upgrade and large consumption.it is suitable for large sale.
