How many kinds of foil are used?
Four. Cable foilCable foil is sealed with aluminum foil and shielding, single or double coated plastic film, an aluminum foil plastic composite #, used as a shield cable. The cable foil needs less oil on the surface and has no holes. It has high mechanical properties, but the overall quality is not high, but the length of the cable needs to be extremely severe.At present, the leading domestic cold rolling mill, universal mill and aluminum foil roughing mill can be produced, but the growth of shopping malls is poor, the domestic demand is 25 thousand tons per year.
Three, decoration foilDecoration foil is a kind of decoration material which is used by aluminum plastic composite way. The aluminum foil is characterized by good color and high reflectivity of light and heat. Mainly used for construction, furniture decoration and some gift box packaging. The use of decoration construction in Chinese foil is from the beginning of 1990s, Shanghai, Beijing, Guangzhou, extending from the center of the city to the country rapidly in recent years, need volume increased dramatically, usually as a building wall and indoor furniture decoration materials, door surface and interior decoration in business organizations is also widely used.The decorative foil has the advantages of heat insulation, moisture proof, sound insulation, fire prevention and easy cleaning, and the appearance is luxurious, the processing is convenient, and the construction device is fast. At present, China's construction and home improvement industry has formed an upsurge in the use of decoration foil. With the rapid development of China's construction industry and the continuous popularization of decoration foil, the amount of decoration foil will be greatly increased. In addition, the choice of decoration foil gift packaging is very popular in foreign countries, in recent years in China to carry out very fast, it is estimated that there will be a better vision.
Two 、 cigarette packing foilChinese is the world's largest cigarette production and consumption country, China currently has 146 large cigarette factory, with an annual output of 34 million of the total cigarette Daxiang, all use cigarette foil packing, the selection of 30% spray plating foil, 70% selection of rolling aluminum foil, rolling aluminum foil consumption of 35 thousand tons, followed by enhancing citizens' health awareness and imported cigarette impact add the required amount of smoke, foil significantly slowed down, estimated in recent years will increase slightly. China cigarette packaging foil accounted for 70% of the total amount of double zero foil, currently there are two or three companies can produce high quality tobacco foil, skill level and the world level is appropriate, but the overall quality of domestic smoke foil with the world level must distance.
The four main uses of aluminium foil are:I. air conditioning foilThe air conditioner foil is a specialized material for making fins for heat exchangers in an air conditioner. In order to improve the surface properties of the plain foil, an anticorrosive inorganic coating and a hydrophilic organic coating are applied before forming to form hydrophilic foil. At present, hydrophilic foil accounts for%1 of the total amount of air conditioning foil, and its utilization ratio will be further improved. In addition, there is a hydrophobic foil, so that the fin surface has hydrophobic function, avoid condensation water adhesion. Because of the hydrophobic foil to improve the appearance of defrost skills to be further studied, the current practice produced little.The thickness of the air conditioner foil is 0.1mm to 0.15mm. With the development of skills, air-conditioning foil further thinning trend, Japan's leading product thickness of 0.09mm. In much of the state, to the aluminum foil with good formability, the arrangement and performance necessary uniform metallurgical defects less small anisotropy, together with the need of high strength, good ductility, uniform thickness, good flatness. Air foil standard and the alloy is relatively simple, suitable for large-scale production, but the market is seasonal, on air foil professional manufacturer, it is difficult to deal with the season and the cold season is no need to demand outstrips supply contradiction.Because of weak stock market needs to move, in recent years China air foil production capacity and skill level of continuous improvement, has formed a large and small, high and low production of aluminum foil for air conditioner company groups, some large companies such as China aluminum, Bohai aluminum products quality has reached the leading level of the world. Because the domestic production capacity is surplus, the market competition is extremely fierce.
