Four uses of aluminum foil

at present, China has become the second largest consumer of aluminum foil after the United States, but the annual consumption per capita is only 0.22kg, equivalent to one tenth to one twentieth of that of developed countries. China's aluminum foil market contains huge business opportunities. The four uses of aluminum foil are:

first, air conditioning foil

air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners, and the early air conditioning foil is plain foil. In order to improve the surface properties of plain foil, anti-corrosion inorganic coating and hydrophilic organic coating are coated before forming to form hydrophilic foil. At present, hydrophilic foil accounts for% 1 of the total amount of air conditioning foil, and its use proportion will be further improved. In addition, there is a kind of hydrophobic foil, which makes the surface of the fin hydrophobic and prevents condensate from adhering. Because the technology of improving the surface defrostability of hydrophobic foil needs further research, there is little actual production at present

the thickness of air-conditioning foil is 0.1mm ~ 0. Focus on the development of organic chemical raw materials and new chemical materials 15mm。 With the development of technology, air conditioning foil has a trend of further thinning. The thickness of Japan's leading product is 0.09mm. In the extremely thin state, aluminum foil must have good formability. Its structure and properties must be uniform, with less metallurgical defects and anisotropy. At the same time, it is required to have high strength, good ductility, uniform thickness and good flatness. The specification and alloy of air conditioning foil are relatively single, which is suitable for large-scale production, but its market is highly seasonal. For professional manufacturers of air conditioning foil, it is difficult to solve the contradiction between short supply in peak season and almost no demand in off-season

due to the market demand, this innovative technology is based on the strong driving force of the utilization of a heat latent curing agent material. In recent years, the production capacity and technical level of air-conditioning foil in China have been continuously improved, and an enterprise group of large, medium, small, medium, high and low production of air-conditioning foil has been formed. The product quality of some large enterprises such as North China Aluminum and Bohai aluminum has basically reached the international advanced level. As domestic production can not be ignored, overcapacity, market competition is extremely fierce

Second, cigarette packaging foil

China is the largest cigarette production and consumption country in the world. At present, there are 146 large cigarette factories in China, with an annual output of 34million cases of cigarettes. Basically, cigarette foil packaging is used, of which 30% are sprayed foil and 70% are rolled aluminum foil. The consumption of rolled aluminum foil is 35000 tons. With the enhancement of people's health awareness and the impact of imported cigarettes from abroad, the growth of cigarette foil demand has slowed significantly, It is expected to increase slightly in recent years. China's cigarette packaging foil accounts for 70% of the total double zero foil. At present, there are twoorthree domestic enterprises that can produce high-quality cigarette foil, and the technical level is equivalent to the international level, but the overall quality of domestic cigarette foil lags behind the international level

III. decorative foil

decorative foil is a decorative material applied in the form of aluminum plastic composite, which makes use of the characteristics of aluminum foil, such as good coloring and high light and heat reflectivity. It is mainly used for decoration of buildings and furniture and packaging of some gift boxes. The application of decorative foil in China's construction industry began in the 1990s. It has spread rapidly from central cities such as Shanghai, Beijing and Guangzhou to all parts of the country. In recent years, the demand has increased sharply. Generally, as a decorative material for the inner walls of buildings and indoor furniture, decorative foil is also widely used in the doors and interior decoration of commercial institutions

decorative foil has the advantages of heat insulation, moisture-proof, sound insulation, fire prevention and easy cleaning, and has luxurious appearance, convenient processing and fast construction and installation speed. At present, China's construction and home decoration industries have formed a boom in the application of decorative foil. With the rapid development of China's construction industry and the continuous popularization of decorative foil application, the demand for decorative foil will increase significantly. In addition, the use of decorative foil packaging gifts is very popular abroad. In recent years, some experts predict that it will develop rapidly in China, and it is expected to have a better prospect

IV. cable foil

cable foil is an aluminum # plastic composite foil formed by using the airtightness and shielding of aluminum foil and coating plastic film on one or both sides, which is used as the shield of cable. The cable foil requires less oil on the surface, no holes, high mechanical properties, low overall quality requirements, but extremely strict length requirements

at present, domestic advanced cold rolling mills, universal mills and aluminum foil roughing mills can produce, but the market growth is poor, and the domestic annual demand is 25000 tons
