(A) of the air-conditioning foil

Air conditioning foil is the manufacture of air conditioner heat exchanger fins of special materials, early use of air-conditioning foil is plain foil. In order to improve the surface properties of foil, coated with a corrosion-resistant inorganic coating and hydrophilic organic coating to form a hydrophilic foil. Hydrophilic foil accounts for 50% of the total air-conditioning foil, the use of the ratio will be further improved. There is also a hydrophobic foil, so that the surface of the fin has a hydrophobic function, to prevent condensation of water adhesion. As the hydrophobic foil to improve the surface defrosting technology to be further studied, the actual production rarely.

Air foil thickness of 0.1mm ~ 0.15mm. With the development of technology, air-conditioning foil has further thinning trend, Japan's leading product thickness of 0.09mm. In a very thin state, aluminum foil to have good formability, its organization and performance must be uniform, less metallurgical defects, anisotropy is small, while requiring high strength, good ductility, uniform thickness, flatness good. Air-conditioning foil specifications and alloys compared to a single, suitable for mass production, but its seasonal market for air-conditioning foil professional manufacturer, it is difficult to solve the peak demand and off-season demand is almost no contradiction.

As a result of strong market demand, in recent years, China's air-conditioning foil production capacity and technology continues to increase, has been formed Dazhong Xiao, high school low production air-conditioning foil business groups, some large enterprises such as North China Aluminum, Bohai aluminum product quality basic Has reached the international advanced level. As a result of excess domestic production capacity, market competition is fierce.

(B) cigarette packaging foil

China is the world's largest cigarette production and consumption of large countries, there are 146 large-scale cigarette factory in China, with an annual output of 34 million total cigarette boxes, basically using cigarette foil packaging, of which 30% of the use of sprayed foil, 70% Aluminum foil, rolled aluminum consumption of 35,000 tons, with the strengthening of people's health awareness and the impact of imported cigarettes, tobacco demand growth was slowed down, is expected to increase slightly in recent years. China's cigarette packaging foil accounted for 70% of the total amount of double-zero foil, there are two or three domestic enterprises to produce high-quality tobacco, technology and international standards, but the overall quality of domestic tobacco and international standards have a certain gap.

(3) decorative foil

Decorative foil is through the aluminum-plastic composite form of decorative materials, the use of aluminum foil coloring is good, high light and heat reflectivity characteristics. Mainly used for construction, decoration and part of the gift box packaging. Decorative foil in China's construction industry is the application from the 20th century, 90 years from Shanghai, Beijing, Guangzhou and other central cities to the rapid spread throughout the country in recent years, a sharp increase in demand, generally as the interior walls of buildings and indoor furniture, decorative materials , In the commercial sector of the facade and interior decoration is also widely used.

Decorative foil with insulation, moisture, noise, fire and easy to clean, etc., and the appearance of luxury, easy processing, construction and installation speed. At present, China's construction, home improvement industry has become the application of decorative foil boom. With the rapid development of China's construction industry and the continuous popularity of decorative foil applications, decorative foil demand will have a substantial increase. In addition, the use of decorative foil gift packaging is very popular in foreign countries in recent years, the rapid development in China is expected to have better prospects.

(D) cable foil

Cable foil is the use of aluminum foil sealing and shielding, single or double-sided coating on the plastic film, the composition of aluminum # plastic composite foil, as the cable shield. Cable foil surface oil with less oil, no holes, with high mechanical properties, the overall quality requirements are not high, but very strict on the length requirements.

Domestic advanced cold rolling mill, rolling mill and aluminum foil roughing mill can produce, but the market growth is poor, the domestic annual demand of 2.5 million tons.
