At present, air conditioner aluminum foil can be divided into several types: plain aluminum foil, coated aluminum foil, corrosion-resistant aluminum foil, hydrophilic aluminum foil, hydrophobic aluminum foil, self-lubricating aluminum foil, and mildew-proof aluminum foil.
The amount of aluminum foil used in air conditioners varies greatly depending on the model and power. To be thinner is a main trend of manufacturing air conditioner aluminum foil. It helps to save the cost of air conditioner radiators with the same heat exchange area.
The coated aluminum foils used in the market are mainly hydrophilic aluminum foils. It is coated with anti-corrosion coating and hydrophilic coating on plain aluminum foil. The surface of the hydrophilic aluminum foil has strong hydrophilicity. When used in air conditioners, it can optimize the ventilation effect of the heat exchanger, thereby increasing the heat exchange rate by 5%. In addition, the hydrophilic aluminum foil also has other advantages such as anti-corrosion, anti-mold, no peculiar smell, etc. It is mainly used for medium and high-end air conditioners.
The thickness of the air conditioner foil is 0.1mm to 0.15mm. With the development of technology, the air-conditioning foil has a trend of further thinning, and the thickness of Japan's current leading product is 0.09mm. To meet the air conditioner requirements, the aircon aluminum foil should satisfy the following requirements:
It is not strictly specified, but because the price of coatings is generally more expensive, the coating is better to be thinner under the premise of meeting the performance requirements. The coating thickness directly affects the performance indicators of the coating, so the coating thickness on the surface of the aluminum foil is required to be uniform.
Coating adhesion is an indicator of the adhesion fastness of aluminum foil to its surface coating. If the coating adhesion is too small, the surface coating of the coated aluminum foil will easily fall off during further processing and use, which will seriously affect the weight of the coated aluminum foil.
After the hydrophilic aluminum foil is used for a period of time, the hydrophilic properties of the surface will be affected by various environmental factors. Therefore, the hydrophilic performance is generally divided into the initial hydrophilicity and the hydrophilicity after the environmental resistance test. The quality of hydrophilic performance is mainly measured by the size of the angle a.
The initial hydrophilicity requirements of general products are a<100, and the hydrophilicity requirements after the environmental resistance test are a<250.
Corrosion resistance is mainly reflected in three aspects: alkali resistance, the resistance to salt spray corrosion and the resistance to heat and humidity.
