Hydrophilic aluminum foil is one of the main materials for manufacturing air conditioners, and is a product which is further surface-treated on the surface of ordinary aluminum foil used for air conditioner production to have a special hydrophilic property. It overcomes the surface of the air conditioner heat sink when the light foil is not corrosion resistant, easy to produce white powder and odor, water bridge between the sheet and the sheet, water droplets stay in the machine for a long time, affecting the heat exchange effect and other shortcomings, so that the air conditioner Low noise and low energy consumption promote energy saving, environmental protection and miniaturization of air conditioners. Compared with the plain foil, its refrigeration efficiency is improved by about 5%, which is a more ideal air-conditioning heat dissipation material. The hydrophilic foil accounts for more than 80% of the total amount of aluminum foil for air conditioning, and the inverter air conditioner uses a hydrophilic foil for exporting air conditioners.
The raw materials used to produce the hydrophilic foil are mainly aluminum foil and paint. There are two types of coatings, one is an organic resin coating for corrosion-resistant treatment of aluminum foil, and is mainly composed of an alkali resin coating, an epoxy resin coating, and a urethane coating. The other is a coating for hydrophilic treatment of aluminum foil, and mainly includes a water glass system, a silica resin system, an organic resin system, and an organic-inorganic composite system.
