Development prospect of aluminium foil
Introduction of several key aluminium foil products(I) air conditioning foilThe air conditioner foil is a special material for the heat exchanger fin of an air conditioner, and an early air conditioner foil is a plain foil. In order to improve the surface properties of the plain foil, an anticorrosive inorganic coating and a hydrophilic organic coating are applied before forming to form hydrophilic foil. Hydrophilic foil accounts for 50% of the total amount of air conditioning foil, and its use ratio will be further improved. There is also a hydrophobic foil, so that the fin surface has hydrophobic function, prevent condensation water adhesion. Because of the hydrophobic foil, the technology of improving surface defrosting needs to be studied further, and the actual production is very little.The thickness of the air conditioner foil is 0.1mm to 0.15mm. With the development of technology, air-conditioning foil has further thinning trend, Japan's leading product thickness of 0.09mm. In the thin state, aluminium foil to have excellent formability, microstructure and mechanical properties of metallurgical defects must be uniform, less small anisotropy, and high strength, good ductility, uniform thickness, good flatness. Air conditioning foil specifications and alloy is relatively single, suitable for mass production, but its market season is strong, for air-conditioning foil professional manufacturers, it is difficult to solve the peak season demand and off-season demand almost no contradiction.Due to strong market demand, in recent years, China's air-conditioning foil production capacity and technology level unceasing enhancement, has formed a large and small, high and low production of air foil enterprise group, some large enterprises such as China aluminum, Bohai aluminum products quality has reached the international advanced level. Because of the excessive domestic production capacity, the market competition is extremely fierce.
(four) cable foilCable foil is the use of aluminum foil sealing and shielding, single or double coated plastic film, an aluminum foil plastic composite #, used as a shield cable. The cable foil requires less oil on the surface and has no holes. It has high mechanical properties, but the overall quality requirements are not high, but the requirements of the length are very strict.Domestic advanced cold rolling mill, universal mill and aluminum foil roughing mill can be produced, but the market growth is poor, the domestic demand is about 25 thousand tons per year.
