(1) Air-conditioning foil
Air conditioner foil is a special material for manufacturing heat exchanger fins for air conditioners. The air conditioner foil used in the early days is plain foil. In order to improve the surface performance of the plain foil, an anticorrosive inorganic coating and a hydrophilic organic coating are applied before forming to form a hydrophilic foil. Hydrophilic foil accounts for 50% of the total air-conditioning foil, and its use ratio will be further increased. In addition, there is a kind of water-repellent foil, which makes the surface of the fins have a water-repellent function to prevent the adhesion of condensed water. As the technology of hydrophobic foil to improve the surface defrosting property needs further research, the actual production is very few.
The air-conditioning foil has a thickness of 0.1mm to 0.15mm. With the development of technology, there is a trend of further thinning of air-conditioning foils. Japan's leading product has a thickness of 0.09mm. In an extremely thin state, aluminum foil must have good formability, its structure and properties must be uniform, metallurgical defects are small, anisotropy is small, and it requires high strength, good ductility, uniform thickness, and good flatness. The specifications and alloys of air-conditioning foils are relatively simple and suitable for mass production. However, the market is highly seasonal. For professional manufacturers of air-conditioning foils, it is difficult to solve the contradiction between demand in peak season and almost no demand in off-season.
Due to the strong market demand, the production capacity and technical level of China's air-conditioning foils have been continuously improved. Now a group of large, medium, small, high-, middle- and low-level production of air-conditioning foils has been formed. The product quality of some large enterprises such as North China Aluminum and Bohai Aluminum has basically reached the international level. Advanced level. Due to excess domestic production capacity, market competition is extremely fierce.
(2) Cigarette packaging foil
China is the largest cigarette production and consumer country in the world. There are 146 large cigarette factories in China, with an annual output of 34 million boxes of cigarettes. They basically use cigarette foil packaging, 30% of which are sprayed foil and 70% are rolled aluminum foil. , The consumption of rolled aluminum foil is 35,000 tons. With the increase of people's health awareness and the impact of imported cigarettes from abroad, the growth of demand for tobacco foil has slowed down significantly and is expected to increase slightly. Cigarette packaging foil in China accounts for 70% of the total amount of double zero foil. There are two or three domestic companies that can produce high-quality tobacco foil. The technical level is equivalent to the international level, but the overall quality of domestic tobacco foil is far behind the international level.
(3) Decorative foil
Decorative foil is a decorative material applied in the form of aluminum-plastic composite, which makes use of aluminum foil's good colorability and high light and heat reflectivity. It is mainly used for decoration of buildings and furniture and part of gift box packaging. The application of decorative foil in China’s construction industry began in the 1990s. It spread rapidly from central cities such as Shanghai, Beijing, and Guangzhou to all parts of the country. It is also widely used in the facade and interior decoration of institutions.
Decorative foil has the advantages of heat insulation, moisture resistance, sound insulation, fire prevention and easy cleaning, etc., and it has luxurious appearance, convenient processing and fast construction and installation speed. China's construction and home improvement industries have formed an upsurge in the application of decorative foils. With the rapid development of China's construction industry and the continuous popularization of decorative foil applications, the demand for decorative foil will increase substantially. In addition, the use of decorative foil packaging gifts is very popular abroad, and the development speed in China is very fast, and it is expected to have a better prospect.
