The hydrophilic
aluminum foil has strong hydrophiicity. It can be used in air conditioning to optimize the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%.In addition, the aluminum fin stock also has other advantages such as anti-corrosion, bacteria resistance and no odor. It is mainly used in high-end air conditioner, refrigerators, automobile air conditioners and automobile water tanks. Welcome to know its properties through the following table.Item of converter foilTechnical parameterFilm thickness1.0-20 µmHydrophilicity Initial hydrophilic angle ≤10°, continuous hydrophilic angle ≤20°AdhesionErichsen test(5 mm deep):no flaking, no delaminationCorrosion resistanceRN≥9.5(72 hours)Alkali resistanceThe coating is completely no bubble after being immersed in 20% NaOH at 20℃ for 3 minutesSolvent resistanceSample weight loss ≤1%Heat resistanceAt a temperature of 200℃ for 5 minutes, its performance and color are unchanged. At a temperature of 300℃ for 5 minutes, the coating film is a little yellowish.Oil resistanceThe coating is without bubble after a 24-hour immersion in volatile oil.Odor OdorlessWear on the moldThere is less wear on the mold.
