(a) Air-conditioning Foil. Air-conditioning foil is a special material for making heat exchanger fins for air conditioners, the early use of air-conditioning foil is a foil. In order to improve the surface properties of the foil, a hydrophilic foil is formed by applying an antiseptic inorganic coating and hydrophilic organic coating before forming. hydrophilic foil accounted for 50% of the total amount of air-conditioning foil, the use of the proportion will be further improved. There is also a water-repellent foil, so that the fin surface with water-repellent function, to prevent condensation water adhesion.
Due to the water-repellent foil to improve the surface defrosting technology needs to be further studied, the actual production is very few. The thickness of the air-conditioner foil is 0.1mm~0.15mm. With the development of technology, air-conditioning foil has a further thinning trend, Japan's leading product thickness of 0.09mm. In a very thin state, aluminum foil to have a good formability, the organization and performance must be uniform, less metallurgical defects, small anisotropy, at the same time requires a higher strength, ductility, thickness uniformity, straightness is good.
Air-conditioning foil specifications and alloys are relatively single, suitable for large-scale production, but its market is strong seasonal, for the professional manufacturer of air-conditioning foil, it is difficult to solve the high season demand and the low season almost no Contradiction. As a result of the strong market demand, China's air-conditioning foil production capacity and technical level has been increasing, has formed a large middle and small, high school low-cost air-conditioning foil enterprise groups, Some large enterprises such as North China aluminum, Bohai Aluminum product quality has reached the international advanced Level.
Because of the overcapacity of domestic production, the market competition is extremely fierce.
(ii) Cigarette Packaging Foil. China is the World's largest producer and consumer of cigarettes, China has 146 large cigarette factories, The annual output of 34 million large boxes of cigarettes, the basic use of cigarette foil packaging, of which 30% using sputter foil, 70% using calendering aluminum foil, Aluminum foil consumption of 35,000 tons, along with the People's Health awareness and the impact of foreign imports of cigarettes, the demand for tobacco foil growth significantly slowed, is expected to increase slightly.
China's cigarette packaging foil accounted for 0 of the total amount of 70%, two or three domestic enterprises can produce high-quality smoke foil, technical level and international level is comparable, but the overall quality of domestic smoke foil and international standards have a certain gap.
(iii) Decorative Foil. Decorative foil is a decorative material used in the form of Aluminum-plastic composite, which utilizes the characteristics of good coloring property of aluminum foil and high reflectivity of light and Heat. Mainly used in construction, furniture decoration and part of the gift box packaging.
Decorative foil in China's construction industry since the beginning of the the 1990s, from shanghai, beijing, Guangzhou and other central cities to spread rapidly throughout the country, the demand has increased sharply, generally as the interior wall and indoor furniture decoration materials, commercial institutions in the façade and interior decoration also has a wide range of Applications. Decorative foil with heat insulation, moisture, noise, fire and easy to clean the advantages, and the appearance of luxury, easy processing, construction and installation Speed. China's construction, Home Improvement Industry has formed the application of decorative foil Craze. With the rapid development of China's construction industry and the continuous popularization of decorative foil applications, the demand for decorative foil will also be significantly increased. In addition, the use of decorative foil packaging gifts Abroad is very popular, in China's rapid development, it is expected to have a better future
