Hydrophilic aluminum foil is one of the main materials for the manufacture of air conditioners. It is a product that is further surface-treated on the surface of ordinary aluminum foil used in air conditioners to make it have special hydrophilic properties. It overcomes the shortcomings of air conditioner heat sinks that are not resistant to corrosion, white powder and peculiar smell are easily produced, water bridges are easy to build between plates, water droplets stay in the machine for a long time, and the heat exchange effect is affected. The air conditioner has low noise and low energy consumption, which promotes the energy saving, environmental protection and miniaturization of the air conditioner.
The production methods of hydrophilic aluminum foil mainly include chemical soaking method and mechanical roller coating method. The mechanical roller coating method is divided into single-layer coating film, double-layer coating film and multi-layer coating film. The chemical soaking method is relatively simple, and the roller coating is more complicated, but the product performance of the roller coating is better than chemical immersion.
