Aluminum foil represents thin plate of aluminum which thickness is 0.2 mm. It is used for various purposes, for example, for wrapping of products, at construction jobs.
Aluminum foil, thanks to the unique properties, finds very broad application in various industries: food, pharmaceutical, electrotechnical, space, construction. It is also often used in life, for example, when warming bath, sauna as she creates effect of thermos, releasing warmly outside. And apply self-adhesive foil to reliable covering of joints and various flexible designs.
Properties of aluminum foil
This material became exclusively popular thanks to a number of valuable properties. First, aluminum foil easily takes the necessary form, even very difficult, it very thin, it is easy to deform it. It is possible to cover with it densely practically any surface. It develops easily, bent, keeping at the same time the durability. Secondly, aluminum is corrosion resistant metal, thanks to availability on surface of protective oxide film. For this reason the foil is used for packing of products. Thirdly, aluminum foil, even the thinnest, absolutely opaque. And it is very important as at influence of UV-radiation the quality of food or chemical product can worsen. Fourthly, aluminum foil – absolutely eco-friendly material, it is possible to process it with 100% completeness.
Besides, thin aluminum foil quickly and completely decays in the earth, and thus, does not pollute the environment.
On the surface of aluminum foil there is no electrostatic tension, dust is not attracted (and it is very important by production of especially exact equipment in a number of industries). Aluminum foil is resistant both to high, and to low temperatures therefore it with success is used also when freezing products, and at their heat treatment. It is non-toxic, does not change organoleptic qualities of foodstuff to which contacts, well protects them from external harmful influences. It is possible to list many useful properties of aluminum foil, but also told enough to make sure of its numerous advantages.
Types of aluminum foil
It is necessary to buy foil proceeding from range of application. For example, if you want to buy foil for packing of products, better select technical. Aluminum foil, depending on assignment, is subdivided into three main groups: technical, food and tape. The technical foil finds the broadest application in the electrotechnical, aircraft manufacturing and motor-car industry. Also it is applied at construction of buildings and separate designs, as thermal insulation material. Such foil at thermal insulation of vent systems, water and sewage pipes, floor and roof is especially irreplaceable. At the same time, thanks to "effect of thermos", the thick layer of material is not necessary. In life as it has been already told, technical aluminum foil is often applied at the equipment of baths of different designs. It provides fast heating of the room and long keeps heat. Thus, aluminum foil allows to cut down significantly costs on heating of bath, sauna. Especially effectively the foil works if to attach it directly on walls and ceiling the pair, mirror party in the room (under facing boards). Besides, it should be noted that the foil at the same time plays paroizolyator role. At the same time, unlike materials of type of roofing material, bitumen, etc., when heating to temperatures over 100 wasps, aluminum foil does not emit hazardous substances. Therefore its use in baths and saunas brings double benefit.
Such foil in areas with hot climate can be used for sun protection. In the simplest option it just needs to be pasted on windows.
The food foil is used for packing of food, tobacco products, cosmetics, drugs. It completely keeps their useful properties, tastes and aromas. It can be seen in thermoses. Tape aluminum foil finds application in construction, for example, at production of wall panels. Also aluminum foil on condition of surface is reinforced, corrugated, laminated. The reinforced foil is used for external isolation of water pipes, corrugated – mainly, for isolation of oil pipelines and gas pipelines. The laminated aluminum foil, thanks to availability of additional layer, provides the best protection of pipes. On production of foil the most part of the aluminum melted in the world leaves. To data, 75% of metal are the share of production of foil for packing of food, 25% - for production needs. Aluminum foil is resistant to high temperatures for this reason it is used for soldering, in the space industry.
