Classification of air-conditioning aluminum foil


1, non-coated aluminum foil

Uncoated aluminum foil refers to an aluminum foil that has been subjected to rolling annealing without any surface treatment. In China 10 years ago, the aluminum foil used for air conditioning heat exchange sheets about 15 years ago was uncoated aluminum foil. About 50% of the heat transfer sheets used in developed countries are still uncoated aluminum foil, while in China, this ratio is around 60%.

2, coated aluminum foil

The so-called coated aluminum foil is a surface re-treatment of the uncoated aluminum foil to give it a special function. In countries with rapid technological development such as Japan and Germany, coated aluminum foil has been used for more than 15 years. In China, the time to use coated aluminum foil is no more than 10 years. According to the characteristics of the surface of the coated aluminum foil, it can be classified as follows:

3, corrosion-resistant aluminum foil

The surface of the corrosion-resistant aluminum foil product has a certain corrosion-resistant protective layer. The air-conditioning heat exchange sheet made of the product can be applied to a relatively harsh area, and the service life of the air conditioner can be significantly improved. At the same time, due to the improvement of the corrosion resistance of the heat exchange sheet, the generation of surface corrosion powder is greatly reduced, thereby improving the ventilation quality and purifying the air in the air conditioning room.

4, hydrophilic aluminum foil

The surface of the hydrophilic aluminum foil has strong hydrophilicity. The hydrophilic properties are determined by the angle formed by the water sticking to the surface of the aluminum foil, as shown in Figure 1. The smaller the a angle, the better the hydrophilic property, and vice versa, the poorer the hydrophilic property. In general, the a angle is less than 35. It is a hydrophilic property. Hydrophilic aluminum foil is generally used on the condenser of an air conditioner. Its main function is to make the moisture in the hot air easy to spread out when it condenses into water droplets on the heat exchange sheet and flow down the sheet. In this way, the ventilation effect of the heat exchanger can be avoided due to the “bridge” of the water droplets between the heat exchange sheets, thereby improving the heat exchange rate of the air conditioner, and saving energy under the same cooling capacity condition. Before, the general hydrophilic aluminum foil on the market has better hydrophilicity in addition to the surface, and also has high corrosion resistance, thereby optimizing the performance of the air conditioner.

5, hydrophobic aluminum foil

Hydrophobic aluminum foil, also known as water repellent aluminum foil, has the same surface properties as hydrophilic aluminum foil. That is, when the condensed water condenses on the surface of the aluminum foil, the contact angle with the aluminum foil is large, generally at 75. the above. The larger the angle, the better the water repellency. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, that is, condensed water is not allowed to remain between the heat exchange sheets. The difference is that the hydrophobic aluminum foil is formed by increasing the contact angle between the condensed water and the heat exchange sheet, so that the condensed water forms a water droplet which is easy to slide, thereby achieving the purpose of removing the condensed water between the heat exchange sheets.

6, self-lubricating aluminum foil

In the process of manufacturing air-conditioning heat-exchange sheets, it is generally necessary to first add lubricating oil to the surface, then punch the edges, and finally wash the lubricating oil with trichloroethylene. Since trichloroethylene is harmful to the human body, in order to reduce this process, a self-lubricating aluminum foil is produced accordingly. Self-lubricating aluminum foil, as its name suggests, does not require a separate addition of lubricating oil during its processing, and the lubrication during the stamping process is carried out by a pre-treated film on the surface of the aluminum foil. Since no special lubrication is required, the subsequent trichloroethylene cleaning and drying process is eliminated.

7, mildew-proof aluminum foil

The mildew-proof aluminum foil is mainly used for the indoor unit of the empty, and its main function is to prevent the surface of the heat exchange sheet from being moldy due to the long time of use or standing, thereby obviously improving the ventilation quality of the air and preventing the abnormal smell, effectively Improve the environment in the air-conditioned room.
