What Is Aluminum Foil Fiberglass Cloth？

Air conditioning foil is a special material for manufacturing heat exchanger fins for air conditioners. The early air conditioning foil was 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. Hydrophilic foil accounts for 50% of the total amount of air conditioning foil, and its use proportion will be further improved. In addition, there is a hydrophobic foil, which makes the fin surface hydrophobic and prevents condensate from adhering. Because the technology of improving surface defrostability of hydrophobic foil needs to be further studied, there is little practical production.

The thickness of air conditioning foil is 0.1mm ~ 0.15mm. 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 microstructure and properties must be uniform, less metallurgical defects and small 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.

Driven by the strong market demand, the production capacity and technical level of air-conditioning foil in China have been continuously improved in recent years. Now there are enterprise groups producing air-conditioning foil in large, medium, small, medium, high and low levels. The product quality of some large enterprises such as Huabei aluminum and Bohai aluminum has basically reached the international advanced level. Due to the excess domestic production capacity, the market competition is extremely fierce.

China is the world's largest producer and consumer of cigarettes. At present, there are 146 large cigarette factories in China, with an annual output of 34 million cases of cigarettes, which are basically packaged with cigarette foil, 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, the growth of cigarette foil demand has slowed down 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, two or three domestic enterprises can produce high-quality cigarette foil, and the technical level is equivalent to the international level, but there is a certain gap between the overall quality of domestic cigarette foil and the international level.

Decorative foil is a decorative material applied in the form of aluminum plastic composite, which makes use of the characteristics of good coloring and high photothermal reflectivity of aluminum foil. 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. The demand has increased sharply in recent years. Generally, as a decorative material for the inner wall of buildings and indoor furniture, it is also widely used in the door and indoor 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 an upsurge 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. It has developed rapidly in China in recent years and is expected to have a good prospect.

Cable foil is a kind of aluminum # plastic composite foil, which is formed by using the tightness and shielding of aluminum foil and coating plastic film on one or both sides, and 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.

Domestic advanced cold rolling mills, rolling mills and aluminum foil roughing mills can produce, but the market growth is poor, and the domestic annual demand is about 25000 tons.
