Mildew-proof aluminum foil is mainly used in the indoor unit of the air conditioner. Its main function is to prevent the surface mold of the heat exchanger from being used or left for a long time, thereby significantly improving the ventilation quality of the air conditioner and preventing the generation of abnormal odors, effectively Improve the environment in air-conditioned rooms.
The main alloy grades of aluminum foil for heat exchangers include 1100, 1200, 8011, 8006, etc. From a usage perspective, air conditioners do not have strict requirements on the chemical composition of aluminum heat exchange fins. Without surface treatment, 3A21 aluminum alloy has relatively good corrosion resistance, high mechanical properties such as strength and elongation, and high hardness. The choice of which alloy to use mainly depends on the final mechanical properties that the material can achieve and the ease of the ant process. For example, rolling of 1100 aluminum alloy with higher purity is easier, while 8011 alloy is more difficult.
