Product Description:

Plain Foil  for Pre-Insulated Insulated Panel

1.Structure of Plain Foil  for Pre-Insulated Insulated Panel

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

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 are the advantages and disadvantages of aluminum foil packaging?
Aluminum foil disadvantages: Low intensity, easily torn, not be used for packaging products. Easy to break when folded, to produce perforations, not acid.
Q:Aluminum foil tape or copper foil tape, which is better at shielding?
I should say they have equal shielding abilities. But as aluminum is more likely to oxidize than copper and not easy to be soldered, copper foil tape is preferred in most of the cases. Electromagnetic shield means using elements made of conductive or ferromagnetic materials to screen at the end of stator core of a large turbo-generator, reducing additional loss and local heating in parts caused by flux leakage at the end of stator winding. In terms of communication, screening is to segregate two spaces to prevent electric field, magnetic field, and electromagnetic wave of one area from reacting to or radiating the other one. To be detailed, screening will encompass interference source that influences components, circuit, assembling, cable or the overall system.
Q:Why aluminum foil should be used in capacitor material of distributors?
The normal metal capacitor, especially CBB21/,DV/, impulse current of its turn-off voltage is very high. The capacitor material of distributors, if the distributors of ignitor can't bear such high impulse current. Using CBB28 or CBB8,in which the capacitor can bear a higher impulse current.The ratio of DT is higher.
Q:Does the aluminum has good thermal insulation
The theory of aluminium foil thermal insulation is reflecting the light. I suggest that you can use the professional thermal insulation and temperature preservation material(phenolic foam board,rock wool,EPSXPS.ect.) and choose the right material according to the requirements.
Q:Why the printing ink dropped when etching the aluminum foil.
3.We can watching from these aspects: there are dust,silk screen,producing ink and other material.The reason for thin ink
Q:As for the aluminum foil reflecting coating of floor heating, which is better?
Kraft paper aluminum foil reflecting coating of floor heating is better. It uses quality PET aluminum laminated film and non-woven fabric thermal insulated material. Featured by high brightness, good fastness, aging resistance, non-dealumination and no thermo printing, PET aluminum laminated film has been preferred in choosing reflecting coating. Kraft paper aluminum foil reflecting coating is a composite material characterized by water resistance, moisture resistance, smoothness, clear printing, thermal insulation and high reflectivity. By combines the characteristics of traditional polystyrene board with reflecting coating, Kraft paper aluminum foil reflecting coating has the features of both EPE and aluminum laminated film and thus becomes very popular in the market.
Q:What's the difference between the cold stamping molding aluminum foil and common aluminum foil package
3.Hot-melt adhesive,resistant to acid and alkali,flexible 4.it has the metallic lustre, strong in light reflection and the luminosity factor reaches to 95%. 5.corrosives,barrier property, waterproof and wetproof,air impermeability and frgrance-hoilding. 6.the stable temperature is [1] -73~371°.
Q:Is the aluminum-foil paper flame retardant?
The aluminum-foil paper is a bond paper made by aluminum foil backing paper and aluminum foil.The main material is aluminum.The pure oxygen of aluminum is 550 degree. When burning aluminum, an oxidation film will form in the air,making the burning become difficult.
Q:The advantages and disadvantages of waterproof aluminum film and aluminum foil
me for use shorten to five years. it is influenced by the environment and quality.5.if the same roll takes this method of coverage, the combination property is nearly the same.
Q:Can aluminum foil be put in microwave oven?
No. The microwave produced by the microwave oven belongs to radio wave frequency band and is about 2500MHz. The features of this frequency band are as follows: 1) It can be absorbed by food and water to make the molecular react violently so as to produce heat. 2) It cannot be absorbed by plastic, ceramic and glass. 3) Metal can be conductive to electricity under the influence of the electric field of microwave. Since thick metal can resist the electric field of microwave and reflect microwave, the inner wall of microwave oven is made by thick metal. Similarly, putting a thick metal container in the microwave oven will make the metal container reflect microwave and thus make the food unheated. However, the electric conduction of thin aluminum foil may cause disastrous reaction. In the course of electric conduction, the temperature of thin metal will rise to cause a fire. At the same time, when met with heat, aluminum foil will shrink and its point will produce sparks which may ignite the combustibles in the oven.
