Hydrophilic aluminum foil is mainly coated with a hydrophilic coating on a common aluminum foil and then coated with an anti-corrosion coating. Of course, there is also no anti-corrosion coating, the price will be cheaper than the anti-corrosion coating, a price is a good thing. Hydrophilic coating materials are not found. Anti-corrosion coatings are mainly chemical methods: chromate method, phosphoric acid-chromate method, non-chromate method, etc.: solution spray method can be used for processing. Coating method: The organic resin coating is mostly an alkali resin, an epoxy resin or a urethane.

The so-called hydrophilic aluminum foil is an aluminum foil which is coated with an anticorrosive coating and a hydrophilic coating on an aluminum foil for air conditioning having a thickness of about 0.1 mm and dried in a drying oven. According to reports, the hydrophilic aluminum foil surface has strong hydrophilicity. When used on air conditioners, the water droplets in the hot air can be easily spread out on the heat exchange sheet and flow down the sheet.

Avoid the ventilation effect of the heat exchanger due to the “bridge” of the water droplets between the heat exchange sheets, thereby increasing the heat exchange rate by 5%. In addition, the hydrophilic aluminum foil has other advantages: anti-corrosion, anti-mold, no odor; due to the water-free beads, the air-conditioning noise caused by the vibration can be correspondingly reduced; the air-conditioning oxidized powder can be prevented from being blown into the room and adversely affect the human body, and is environmentally friendly. Requirements; can improve the corrosion resistance and weather resistance of the heat exchanger, and extend the service life of the heat exchanger.
