Aluminum Foil for Air Conditioner from aluminium foil manufacturer

  Aluminum boasts so many advantages that it is more and more widely applied. It’s of small density, good heat conductivity, excellent workability, environmental properties and low cost. As a result, aluminium foil manufacturers are trying to replace traditional raw materials with aluminum. Take air conditioners for example. Manufacturers use aluminum as conductor sheets of heat exchangers. As a result, a new term has come into being in the industry: aluminum foil for air conditioner.

  Aluminium foil roll for air conditioners has been developed for over 20 years in China and got fast development in the past 10 years when air conditioners were winning more and more popularity. Nowadays air conditioners are becoming smaller and more efficient. Correspondingly the heat conductor sheets becomes thinner and stronger. In 1980s the thickness was about 0.15mm but now it reaches as small as 0.09mm. In addition, coated conductor sheets of various functions have been developed to extend air conditioners’ service life, reduce power consumption, improve ventilation effect and strengthen refrigeration effect. There are now conductor sheets of anti-rust type, surface water-loving function, water-repellent function, mildewproof type and self-lubricating type. This makes aluminium foil uses wider and wider.

  Anti-rust conductor sheets of aluminum foil for air conditioners are coated with a protective layer on the surface. Air conditioners with such sheets can be used in regions of severe conditions and have obviously longer life than ones. In addition, anti-rust ability of the sheets prevents production of corrosive dust on the surface, which helps to improve ventilation and eventually air quality of the service area. Water-loving aluminium foil rolls are usually applied to evaporators. Their main function is to lead clotted water down the sheets so that water will not accumulate on the sheets, which will greatly reduce ventilation effect as well as heat exchanging effect. Generally speaking, water-loving sheets also have anti-rust ability. Self-lubricating sheets have no lubricant oil but a thin layer of lubricating film, which avoids harmful influence on human body.

Aluminum foil is the perfect packaging material

Because of its excellent characteristics, aluminum foil is widely used in food, beverage, cigarettes, pharmaceuticals, photographic substrates, household articles, etc. It is usually used as packaging materials; electrolytic capacitor materials; insulation materials for buildings, vehicles, ships, houses, etc. It can also be used as decorative gold and silver wire, wallpaper and decorative trademarks of various stationery, printing products and light industrial products. In all the above applications, the most effective way to develop the performance of aluminium foil is as packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, shading, wear-resistant, fragrance-preserving, non-toxic and tasteless, but also because of its elegant silver-white luster, easy to process beautiful patterns and patterns of various colors, so it is more likely to be favored by people’s aluminum foil tape.

With the improvement of people’s living standards and the development of tourism, the demand for beer, soda and other beverages and canned food is increasing day by day, which requires modern packaging and decoration to facilitate competition in the international market. In order to meet the market requirements, people have developed good shielding plastic film and spray foil packaging materials, but their comprehensive properties are not as good as coating and lamination processing can be made up and improved.

After aluminum foil deflector beanie is compounded with plastics and paper, the shielding property of aluminium foil is integrated with the strength of paper and the thermal sealing property of plastics, which further improves the shielding properties of water vapor, air, ultraviolet ray and bacteria, which are necessary for packaging materials, and greatly expands the application market of aluminium foil. Aluminum foil manufacturer is well protected because of its full isolation from light, humidity and air outside. Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that food does not deteriorate for at least one year. Moreover, heating and unpacking are very convenient and popular with consumers.

Therefore, it can be said that aluminium foil is a kind of perfect packaging material with many excellent properties, which fully shows its broad application prospects in many fields. In order to improve rolling efficiency and quality of heavy duty aluminum foil products, modern aluminium foil rolling mills are developing in four directions: large coil, wide width, high speed and automation. The roll width of contemporary aluminium foil mill has reached more than 2200 mm, the rolling speed has reached more than 2000 m/min, and the coil weight has reached more than 20 t. The automation level of the rolling mill is also greatly improved. AGC is generally installed, and AFC is mostly installed. Aluminum foil industry is facing a period of rapid development.

How to use aluminum foil sheet better

Aluminum foil sheet is a common spare in home cabinets. It has the advantages of low price, easy to use, disposable, no cleaning, high temperature resistance and heat preservation.

(1) Oil-proof and cleaning aids. First of all, we can fold the aluminum foil at a more beautiful angle and spread it on the plate. Then we can put on greasy dishes. After eating, as long as the aluminum foil is removed, the cleaning can be done more easily. Similarly, it can also be laid on the dipping board to cut greasy food materials, so as to prevent the dipping board from being difficult to clean. Or before cooking, the aluminum foil can be pasted on the wall in front of the gas stove, so as to avoid the oil stains sprayed difficult to remove.

(2) Carbon baking and flavor enhancement of wrapped food materials, of course, can also be wrapped in aluminum foil for barbecue, such as corn, it can lock the fresh and sweet flavor of food materials! Aluminum foil generally has a light and fog surface. One side of aluminum foil is bright, the other side is not bright, how to use it? aluminum foil shiny side up or down.Aluminum foil is divided into smooth surface and fog surface, so which side should be directed towards the photothermal place? Fog surface is easier to absorb heat, so the fog should be directed towards the photothermal place, in order to play its role. Therefore, when baking food, wrap the food in the bright surface of aluminum foil and face the charcoal fire in the fog, the food is easy to bake.

Some people say that barbecuing with aluminium foil can cause cancer, but the Health Bureau points out that there are no reports about the toxic substances produced by barbecuing food covered with aluminium and tin foil. However, based on safety considerations, the Department of Health advises consumers not to drop acid substances such as lemon juice into aluminium foil when baking food wrapped in aluminium foil, because aluminium foil is a metal. When metals are mixed with acid substances, chemical changes will occur, which is prone to produce harmful substances to human body.

(3) It can help freeze quickly. Meat or seafood bought from the market can be wrapped in fresh film, then wrapped in a layer of aluminum foil art into the freezer, so that food can be frozen faster and keep food fresh!.

And don’t throw away used aluminum foil like this! Let’s reuse them again! 1. We can crush used aluminum foil into a small ball and throw it into the drain hole of the dishwasher. The aluminium foil ball will collide with the drainage hole after being washed by water, which will produce metal ions. The drainage hole is not easy to stick to the greasy residue of kitchen and has the function of deodorizing.

(4) There are many edges and corners in the rolled aluminium foil, which can scrape like sandpaper. At this time, it can be used to scrape the peel of potatoes, burdock, ginger and other fruits without worrying about too much peeling, and the details are easy to peel, becoming a safe peeler.

(5) It can also be used to remove the burning part of the bottom of the pot. However, if the family is using stainless steel pot, avoid using this method, easy to scratch.

(6) The blunt scissors in the home can easily be restored by cutting them on two or three layers of aluminum foil on grill. Similarly, you can also fold several overlapping sheets of aluminum foil, and then cut them slowly with a kitchen knife, as a ready-made grindstone!

(7) It may not be necessary in the tropics. In countries like Japan, Europe and the United States where winter snows, when the weather is cold, drainage pipes are liable to freeze and water cannot come out. At this time, the water pipe can be wrapped with non stick aluminum foil, which is said to insulate the frozen air.

Classification of aluminum foil in details

Aluminum foil is a kind of very thin aluminium coil, strip or sheet obtained by rolling aluminium and aluminium alloy strip coil. Aluminum and aluminium alloy sheets and strips with thickness less than 0.2mm are generally referred to as aluminium foils.

Classification of aluminium foil:

According to the shape, it can be divided into rolled and flaky aluminum foil. Aluminum foil products are mostly supplied in rolls, and only a few handicraft packaging users use aluminum foil sheet.

According to the thickness, it can be divided into three kinds: thick aluminum foil, single zero aluminum foil and double zero aluminum foil. Thick foil is 0.1-0.2mm thick foil, single zero foil is 0.01mm thick foil and less than 0.1mm thick foil, double zero foil is thickness of the decimal point after two zero foil.

(3) According to the state, the main foils are hard aluminum foil, soft aluminum foil, semi-hard aluminum foil, one quarter of hard foil and three quarters of hard foil.

(4) According to the surface state, it can be divided into single-sided aluminum foil and double-sided aluminum foil.

(5) According to the use, it can be divided into packaging aluminum foil, commodity aluminum foil, electrical equipment aluminum foil and construction aluminum foil.

Properties of aluminium foil:

Aluminum foil has thin and light material, high specific strength, good gloss, high thermal conductivity and conductivity, high moisture-proof, non-toxic, tasteless, good optical rotation, thermal insulation and good corrosion resistance.

Aluminum foil for electromagnetic shielding

The shielding effectiveness of aluminium foil depends upon the type of incident field (electric, magnetic, or plane wave), the thickness of the foil, and the frequency (which determines the skin depth). Shielding effectiveness is usually broken down into a reflection loss (the energy bounces off the shield rather than penetrates it) and an absorption loss (the energy is dissipated within the shield).

Aluminum foil for electromagnetic shielding:

Excellent High Frequency RF Shielding characteristics

Effective barrier against Low Frequency AC Electric Fields when grounded.

Electrically Conductive

Weather Resistant

Can be used as a Vapor Barrier – not breathable

Heavy Duty / Tear Proof

Flexible and light weight which allows for an easy installation

Safe to handle and non-toxic

Although aluminium is non-magnetic, it is a good conductor, so even a thin sheet reflects almost all of an incident electric wave. At frequencies more than 100 MHz, the transmitted electric field is attenuated by more than 80 decibels (dB) — however actual energy absorption is minimal: the remaining high-frequency rf energy is almost perfectly reflected from uniform flat aluminium surface, and thus, reflected signal may continue to propagate internally, and if holes or passages of suitable geometry exist in the shield, signal propagation may continue out through those, the aluminium being good material for implementation of a microwave-frequency waveguide.

Thin sheets of aluminium are not very effective at attenuating low-frequency magnetic fields. The shielding effectiveness is dependent upon the skin depth. A field travelling through one skin depth will lose about 63 per cent of its energy (it is attenuated to 1/e = 1/2.718… of its original energy). Thin shields also have internal reflections that reduce the shielding effectiveness.For effective shielding from a magnetic field, the shield should be several skin depths thick. Aluminium foil is about 1 mil (25 μm); a thickness of 10 mils (250 μm) offers less than 1 dB of shielding at 1 kHz, about 8 dB at 10 kHz, and about 25 dB at 100 kHz. At these frequencies a ferromagnetic material such as mild steel is much more effective, due to different and complementary electromagnetic permeability properties, and common practical shielding implementations utilise both an inner high-frequency reflective material such as aluminium, preferably bonded (via annealing or electroplating, done to avoid capacitance between separated layers), to a more substantial structural ferromagnetic shell, usually mild steel (in specialized applications, more expensive, less structurally useful and less workable materials may be preferred.) Despite the relative low mass density of aluminium, this design is usually both lighter and more effective than an equivalently absorptive design utilizing aluminium alone.

What is the properties of aluminum foil

What is aluminium foil

Aluminium foil is a very thin sheet of rolled aluminium supplied in its pure form (‘commercial purity’) or in a variety of alloys and tempers which give a wide choice of tensile properties.

The thickness of aluminum foil sheets ranges from the thinnest currently produced commercially at about 0.0065 mm (or 6.5 µm) to the defined upper limit of 0.2 mm (or 200 µm). Material thicker than 0.2 mm is defined as sheet or strip.

Aluminium foils thicker than 25 μm are impermeable to oxygen and water. Foils thinner than this become slightly permeable due to minute pinholes caused by the production process.

Aluminium foil has a shiny side and a matte side. The shiny side is produced when the aluminium is rolled during the final pass. It is difficult to produce rollers with a gap fine enough to cope with the foil gauge, therefore, for the final pass, two sheets are rolled at the same time, doubling the thickness of the gauge at entry to the rollers. When the sheets are later separated, the inside surface is dull, and the outside surface is shiny. This difference in the finish has led to the perception that favouring a side has an effect when cooking. While many believe (wrongly) that the different properties keep heat out when wrapped with the shiny finish facing out, and keep heat in with the shiny finish facing inwards, the actual difference is imperceptible without instrumentation. Increased reflectivity decreases both absorption and emission of radiation. Foil may have a non-stick coating on only one side. The reflectivity of bright aluminium foil is 88% while dull embossed foil is about 80%.

Surface finish

Corrosion Resistance

The naturally-occurring surface oxide on all aluminium in the presence of oxygen in the atmosphere acts as a shield and renders foil substantially corrosion resistant. Aluminium is also chemically resistant in contact with substances in the pH range 4 to 9.

Compatibility with food and chemicals

Non-reactive except to substances of high acidity or alkalinity (see Corrosion Resistance). Resistant to most common compounds in solution.

Formability

Dead fold

Non-absorbency

Non-absorbent and proof against grease, oil, water and other liquids.

Hygiene

Foil is sterile following annealing, and does not harbour or support the growth of bacteria.

Toxicity

Aluminium is present in many fresh vegetables and is non-toxic in amounts and compounds normally encountered. The metal does not accumulate in the body and is non-reactive with virtually all foods, drugs and cosmetics.

Taste, odour

Tasteless and odour-free, alu foil imparts no detectable taste or odour to foodstuffs.

Opacity

Foil is a solid metal. It transmits no light and is a total barrier to light including the UV spectrum.

Reflectivity

Reflects approximately 98% of radiant heat and light.

Non-magnetic

Aluminium is insignificantly magnetic and therefore provides excellent electrical shielding.

Recyclability

Aluminium is easily recycled. Plain aluminium foil can be compacted and re-melted. Laminated aluminium is processed to separate the supporting layers and the aluminium residue is reused in other applications. In addition, the energy contained in the thin foil component of a laminate can be recovered in the form of heat.

What is extra heavy duty aluminum foil

Sometimes you need something a little stronger than standard aluminum foil. That’s where heavy duty aluminum foil comes in. Our heavy duty foil offering is ideal for tough jobs like:

lining pans for use in the oven

freezing meals ahead or storing leftovers

making foil packets to lock in moisture and flavor when you grill

Where this really matters is when you’re using aluminum foil for cooking. Since regular aluminum foil is thinner than the heavy-duty version, it doesn’t stand up to high heat and weighty items as well.

Heavy duty aluminum foil offers perfect protection against both high heat and freezing cold. Heavy Duty Foil is also available in a wider 18 inch roll, making it perfect for covering or lining larger roasting pans or making or folding larger foil packets.

Aluminum foil rolls and sheets come in a variety of thicknesses, widths, and lengths. Manufacturers often make the width and length of the foil roll easy to find, but the thickness of the foil is often not advertised. Most manufacturers use terms like standard duty, heavy duty, and extra heavy duty to describe foil thickness. Finding the actual thickness from a foil box or manufacturers website is not likely.

This type of heavy duty foil is thicker and sturdier than regular aluminum foil. It’s tough enough to stand up to high heat, heavy food items, and long-term storage in the freezer. Because of the extra thickness, it’s also a better choice for campfire packets.

Regular /Standard Duty and extra heavy duty aluminum foil are made of the same material, but there’s a key difference: the thickness of the foil.

Standard Duty Aluminum Foil – Most standard duty aluminum foil rolls are economical aluminum foil rolls for commercial and home aluminum foil sheets use. Home use standard duty foil rolls are often between 75 ft. and 250 ft. long, offered in a variety of widths. The majority of foil rolls labeled as “Standard Duty” are between .0004 thick and .0007 thick. Which at best is slightly over or one half of a mil in thickness.

Thickness of Aluminum Foil

Heavy Duty Aluminum Foil – By far the most common aluminum foil used for home and commercial use. Most home users buy 75 ft. rolls of Reynolds aluminum foil or a comparable brand for home use. Heavy duty foil provides extra strength and tear resistance. Many cooks use it for baking, grilling, and storage. Most Aluminum foil rolls labeled “Heavy Duty” are between .0008 thick and .001 thick. The extra three thousandths of an inch makes a big difference for a variety of applications.

In a word,This extra-heavy duty aluminum foil comes in a box with a standard cutting edge. It is good for use in cooking, serving and freezing food. Lining pans with roll before cooking makes cleanup easy. Use for grilling to lock in flavor and for freezing to prevent freezer burn. Material(s): Aluminum; Length: 500 ft; Width: 18 in; Packing Type: Box.

What are the processes of aluminium foil for air conditioning

There are two processes for aluminium foil for air conditioning:

(1) Cast rolling -cold rolling trimming -cold rolling -box rolling slitting- finished product annealing -packaging.

(2) Ingot -homogenization annealing -hot rolling -cold rolling- trimming cold rolling -box rolling slitting -finished product annealing -packaging.

Aluminum foil can be divided into industrial aluminum foil and packaging aluminum foil. The chemical composition of industrial aluminium foil is relatively pure, and its thickness is 0.005-0.2 mm. It is mainly used as capacitors, insulation materials and moisture-proof materials in electrical and electronic industries. The thickness of packing aluminium foil is generally 0.007-0.1 mm. There are many kinds of products, such as flat foil, printing foil, colored printing foil and laminated foil. They are mainly used as packaging materials for food, tea, cigarettes, etc.

The smaller thickness and width of aluminium foil produced by belt production method can reach 0.0025 mm and 1800 mm respectively.

Aluminum foil rolling is seamless rolling, and the rolls are always in the state of elastic flattening. During rolling, the thickness of alu foil can be controlled by adjusting rolling force, rolling speed and tension. In rough rolling, the thickness ofalu foil is controlled by rolling force; in finishing rolling, the alu foil thickness decreases with the increase of rolling speed; the greater the tension, the smaller the thickness; in order to prevent fragmentation, the tension is usually chosen as 0.2-0.4 of standard yield strength_0.2 of foil.

In low-speed rolling, the “thick oil-a00 aluminium plate rdquo” is often added to lubricating oil, or “thin oil” is used to adjust the rolling thickness of aluminium foil. Lubricant and roll condition have a very important influence on aluminium sheet foil quality.

Aluminum foil billet comes from cold rolled aluminium coil. It is generally pre-annealed at 340-480 C, and its thickness is 0.4-0.7mm. The pass deformation rate is about 50% and the total deformation rate is over 95%. The foil whose finished thickness is less than 0.01-0.02 mm should be rolled and rolled in double sheets.

What thickness is used for packaging aluminium foil

What thickness is used for packaging aluminium foil?

Generally, the thickness of packaging aluminium foil is between 0.03mm and 0.1mm.

Due to the full insolation of the packaged goods from the outside light, humidity and gas, the packaged goods are well protected. Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that food does not deteriorate for at least one year. Moreover, heating and unpacking are very convenient and popular with consumers.

Aluminum foil has a clean, hygienic and shiny appearance. It can be integrated with many other packaging materials, and the printing effect of the surface of aluminum foil is better than that of other materials. In addition, aluminum foil has the following characteristics:

(1) The surface of aluminium foil is extremely clean, sanitary, and no bacteria or microorganisms can grow on it.

(2) Aluminum foil is a non-toxic packaging material, which can be directly contacted with food without any health hazards.

(3) Aluminum foil is a odorless and odorless packaging material, which will not make the packaged food have any odor.

(4) If the aluminum foil pans itself is not volatile, the packaged food will never dry or shrink.

(5) Whether at high temperature or low temperature, there is no oil infiltration in aluminum foil.

(6) Aluminum foil is an opaque packaging material, so it is a good packaging material for sunshine products, such as margarine.

(7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. It can also create containers of various shapes at will.

(8) Aluminum foil has high hardness and tension strength, but its tearing strength is small, so it is easy to tear.

(9) Aluminum foil itself can not be heated and sealed, so it must be coated with heat-resistant materials, such as PE, in order to be heat-sealed.

(10) Aluminum foil may have adverse reactions when it comes into contact with other heavy metals or heavy metals.
