Aluminum Foil Has Been Widely Used
Jul 19, 2017

The four uses of aluminum foil are:

Air conditioner Foil

Air conditioner foil is the special data of heat exchanger fin for air conditioner, and the early use of air conditioner foil is the foil. In order to improve the appearance of the foil performance, before the formation of anti-corrosion inorganic coating and hydrophilic organic coating, forming hydrophilic foil. The current hydrophilic foil account for the total amount of air conditioner in the%1, its utilization ratio will further progress. Aluminum Foil There is also a kind of hydrophobic foil, so that fin surface has a hydrophobic function, to avoid condensation water adhesion. Because the hydrophobic foil to improve the appearance of defrosting skills to be further discussed, the current practice produces little.

The air conditioner foil thickness is 0.1mm~0.15mm. With the development of skills, air conditioning foil to further reduce the trend, Japan today's leading product thickness of 0.09mm. Aluminum Foil In the extremely thin state, the aluminum foil must have the good formability, its arrangement and the performance is necessary even, the metallurgical flaw is few, each anisotropy is small, together needs the intensity high, the ductility is good, the thickness is homogeneous, the flatness is good. Air conditioning foil standard and alloy relatively single, suitable for large-scale production, but its seasonal strong, about air conditioning foil professional manufacturers, Aluminum Foil it is difficult to deal with the peak season demand and cold season almost no need contradiction.

Because of the weak stock market needs, in recent years, China's air conditioning foil production capacity and technical level of continuous progress, has been formed in large and medium-sized, high school low production air-conditioning foil company groups, Aluminum Foil some large companies such as North China aluminum, Bohai Aluminum product quality has reached the world leading level. Because the domestic production capacity is excessive, the market competition is unusually fierce.

II. Cigarette packaging foil

China is the world's largest cigarette production and spending power, currently China has 146 large-scale cigarette factories, annual output of 34 million large cartons of cigarettes, the basic choice of cigarette foil packaging, in which 30% selected spray foil, Aluminum Foil 70% of the use of calendering aluminum foil, calendering of aluminum foil consumption of 35,000 tons, followed by the increase in citizen health awareness and foreign import cigarette impact, smoke foil need to add a significant slowdown, Aluminum Foil estimated in recent years will be slightly added. Chinese cigarette packaging foil accounted for 0 foil total of 70%, the current domestic two or three companies can produce high-quality tobacco foil, skill level and world-level appropriate, but the overall quality of domestic tobacco foil and the world standard has a certain distance.

III. Decoration Foil

Decoration foil is an aluminum-plastic composite of the use of the decoration materials, the use of aluminum foil color good, light and thermal reflectance characteristics. First used for construction, furniture decoration and a part of gift box packaging. Decoration foil in China's construction industry in the use of the beginning of the the 1990s, from Shanghai, Beijing, Guangzhou and other central cities to the rapid extension of the country, in recent years need to increase the volume, usually as a building interior wall and interior furniture decoration information, in the commercial organization of the façade and interior decoration is also widely used

Decoration foil with heat insulation, moisture, noise, fire and easy to clean and other advantages, and the appearance of luxury, processing facilities, construction equipment speed. Currently China's construction, decoration industry has formed the use of decorative foil craze. Aluminum Foil Following the rapid development of China's construction industry and the continuous popularization of decoration foil, the need for decoration foil will be significantly added. Other, the selection of decoration foil packaging gifts in foreign countries very popular, in recent years in China's rapid development, it is expected to have a better vision.

IV. Cable FOIL

Cable foil is the use of aluminum foil airtight and shielding, single-sided or double-sided coating on the plastic film, composed of aluminum # plastic composite foil, used as a cable shield. The cable foil needs the outward appearance to carry the oil quantity little, has no hole, has the high mechanical performance, the overall quality need is not high, but to the length need extremely stern.

At present, the domestic leading cold rolling mills, universal mill and aluminum foil roughing mill can be produced, but the growth of the mall is poor, the domestic needs of 25,000 tons per year.

Aluminum foil has a variety of classifications, different aluminum foil also has a different role. The following simple classification of aluminum foil, for reference only!

According to the thickness of aluminum foil, shape, state or material can be classified.

Aluminum foil According to thickness difference can be divided into thick foil, single 0 foil and double 0 foil. ① thick foil: thickness of 0. 1~0. 2mm foil. ② Single 0 Foil: thickness of 0. OLMM and less than 0. 1mm/foil. ③ Double 0 Foil: The so-called double 0 foil is in its thickness of MM as the unit of measurement when the decimal point has two zero foil, usually the thickness of less than 0.0075mm. Aluminum Foil When expressed in English, the thick foil is called "heavy Gaugefoil", the single 0 foil is called "Medium Gaugefoil", and the double 0 foil is called "lightgaugefoil". Foreign sometimes the thickness of ≤40ltm aluminum foil called light gauge foil, and the thickness of the aluminum foil >40BTM collectively known as heavy Gaugefoil.

Aluminum foil by shape can be divided into rolled aluminum foil and flaky foil. Aluminum foil deep processing of wool most of the roll-like supply, Aluminum Foil only a few handicraft packaging occasions only with flaky foil.

Aluminum foil According to the state can be divided into hard foil, semi-rigid foil and soft foil. ① hard foil: After rolling without softening treatment (annealing) of aluminum foil, without degreasing treatment, the surface of the residual shantou. Therefore, the hard foil in the printing, laminating, coating must be done before degreasing treatment, if used for forming processing can be directly used. ② semi-hard foil: aluminum foil hardness (or strength) between the hard foil and the soft foil, usually used for forming processing. ③ Soft foil: After the rolling after full annealing and softened aluminum foil, the material is soft, the surface is not residual oil. At present, most areas of application, such as packaging, laminating, electrical materials, are used in soft foil.

Aluminum foil According to the surface state can be divided into one light aluminum foil and two light aluminum foil. ① one side of the light aluminum foil: Double rolled aluminum foil, after the volume of light,-surface hair, such as aluminum foil is called a light aluminum foil. The thickness of a light foil usually does not exceed O. 025mm. ② Two-sided light aluminum foil: Single sheet rolling aluminum foil, both painting and roll contact, aluminum foil on both sides of the surface roughness of the rollers are divided into mirror two surface light aluminum foil and ordinary two-sided light aluminum foil. Two surface light aluminum foil thickness is generally not less than 0. 01mm.

Aluminum foil According to the state can be divided into the element foil, embossed foil, composite foil, coated foil, color aluminum foil and printed aluminum foil. ① foil: After rolling, Aluminum Foil no other processing of aluminum foil, also known as light foil. ② Embossed Foil: The surface is embossed with various patterns of aluminum foil. ③ Composite Foil: The aluminum foil and paper, plastic film, cardboard laminating in-formed composite aluminum foil. ④ coated Foil: The surface is coated with various types of resin or lacquer foil. ⑤ Colored aluminum Foil: the surface is coated with a single color of aluminum foil. ⑥ Printing aluminum Foil: by printing on the surface to form a variety of patterns, patterns, text or picture of the aluminum foil, can be a color, up to 12 kinds of color.

Aluminum foil with light weight, airtight and cladding of good and so on-series of advantages, therefore, in many sectors of the national economy and People's daily life to obtain a wide range of applications, but at present it is mainly used in packaging, electromechanical and construction of the three major areas.
