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 foil | Technical parameter |
Film thickness | 1.0-20 µm |
Hydrophilicity | Initial hydrophilic angle ≤10°, continuous hydrophilic angle ≤20° |
Adhesion | Erichsen test(5 mm deep):no flaking, no delamination |
Corrosion resistance | RN≥9.5(72 hours) |
Alkali resistance | The coating is completely no bubble after being immersed in 20% NaOH at 20℃ for 3 minutes |
Solvent resistance | Sample weight loss ≤1% |
Heat resistance | At 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 resistance | The coating is without bubble after a 24-hour immersion in volatile oil. |
Odor | Odorless |
Wear on the mold | There is less wear on the mold. |
