Air Conditioner Aluminum Foil for Fin Stock

Air conditioner aluminum foil is a special material for the manufacture of heat exchanger fins for air conditioners. The aircon aluminum foil used in the early days was plain foil. It refers to aluminum foil that has been rolled and annealed without any form of surface treatment.

In order to improve the surface properties of plain foil, coated aluminum foil is to reprocess the surface of non-coated aluminum foil to make it have some special function. Different types of air conditioner foil are generated like corrosion-resistant aluminum foil, hydrophilic aluminum foil, hydrophobic aluminum foil,etc.

The surface of the corrosion-resistant aluminum foil has a certain anti-corrosion protective layer. The air-conditioning heat exchange fins made of this foil paper can be used in relatively harsh areas and can significantly improve the service life of the air conditioner.

At the same time, due to the improvement of the corrosion resistance of the heat exchange sheet, the generation of surface corrosion powder is greatly reduced, thereby improving the ventilation quality and purifying the air in the air-conditioned room.

At present, hydrophilic foil accounts for 50% of the total amount of air-conditioning foil, and the proportion of its use will be further increased. Fins with good hydrophilicity can improve the heat exchange efficiency of the air conditioner heat exchanger, significantly save power consumption, and effectively reduce the distance between the fins of the heat exchanger, thereby reducing the volume of the air conditioner.

Hydrophobic aluminum foil is also called water-repellent aluminum foil, and its surface properties are just the opposite of hydrophilic aluminum foil. That is, when the condensed water condenses on the surface of the aluminum foil, the contact angle formed with the aluminum foil is relatively large, generally above 75 degrees. The larger the angle, the better the water repellency.

In the process of manufacturing the air-conditioning heat exchange fin, lubricating oil should be added to its surface first, then punching and flanging, and finally washing off the lubricating oil with trichloroethylene. Since trichloroethylene is harmful to the human body, in order to reduce this process, self-lubricating aluminum foil is produced accordingly.

The manufacturing of jumbo aluminum foil for air conditioner includes unwinding, pretreatment, surface roll coating( first roll coating → first drying → second roll coating → second drying) and coiling.

The function of pretreatment is mainly to enhance the bonding force between the coating and the aluminum foil. The function of the coating plays the role of increasing the hydrophilicity and corrosion resistance of the product. Welcome to leave message below to inquire aluminum foil jumbo roll price.
