The thickness of air conditioning foil is 0.1 mm to 0.15 mm. With the development of technology, aluminum foil for air conditioning has good formability. Its structure and performance must be uniform, with few metallurgical defects and small anisotropy. At the same time, it requires high strength, good ductility, uniform thickness, and good straightness. Aluminum foil for air conditioners has a single specification and alloy and is suitable for mass production.
Aluminum foil for air conditioning is a special material for heat exchanger fins, and plain foil is the earlier aluminum foil for air conditioning. In order to improve the surface properties of plain foil, anti-corrosion inorganic and hydrophilic organic coatings are applied before forming to improve its surface properties. Form a hydrophilic foil. Hydrophilic foil currently accounts for 50% of the total aluminum foil used in air conditioners, and the usage proportion will further increase. There is also a hydrophobic foil that makes the surface of the fins hydrophobic and prevents condensation water from adhering.
