Air-conditioning is indispensable to escape the heat in summer. Klima binlerce eve girerken, aynı zamanda sürekli gelişiyor. Şu anda, klimalar giderek minyatürleşme yönünde gelişiyor, yüksek verim, ve uzun ömür. The air-conditioning heat exchange fins are also correspondingly developed in the direction of ultra-thin and high strength. In the 1980s, the thickness of the heat exchange fins was 0.15-0.2 ram, but nowadays, the thickness is only between 0.09 Ve 0.15 mm. In order to increase the life of the air conditioner, reduce the power consumption, improve the ventilation quality and increase the refrigeration effect, a variety of functions of heat fins have been produced.
The air-conditioning foil has a thickness of 0.1mm to 0.15mm. With the development of technology, there is a trend of further thinning of air-conditioning foils. Today, the thickness of Japan’s leading product is 0.09mm. In the ultra-thin state, aluminum foil must have good formability, its arrangement and performance must be uniform, less metallurgical defects, and small anisotropy. Aynı zamanda, it needs high strength, iyi süneklik, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. Fakat, the market has strong seasonality. Professional manufacturers of air-conditioning foils can hardly deal with the contradiction between oversupply in peak seasons and no need in cold seasons.
Due to the weak stock market demand, the production capacity and skill level of China’s air-conditioning foil have been continuously improved in recent years, and a group of companies producing air-conditioning foils of large, medium and small, high, middle and low levels has been formed. The product quality of some large companies such as North China Aluminum and Bohai Aluminum It has basically reached the world’s leading level. Because of the overcapacity of domestic production, market competition is extremely fierce.
Air conditioner aluminum foil can be divided into 7 categories according to its processing technology and performance characteristics.
Non-coated aluminum foil refers to aluminum foil that has been rolled and annealed without any form of treatment on the surface. Benim ülkemde 10 Yıllar önce, ve hakkında 15 Yıllar önce, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. Şu anda bile, hakkında 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, benim ülkemdeyken, bu oran yaklaşık 60%.
The so-called coated aluminum foil is to reprocess the surface of non-coated aluminum foil to make it have a certain special function. In countries with fast technological development such as Japan and Germany, coated aluminum foil has been used for more than 15 yıllar. Benim ülkemde, kaplanmış alüminyum folyo kullanımı aşılmamaktadır 10 yıllar.
Korozyona dayanıklı alüminyum folyo ürününün yüzeyi belirli bir korozyon önleyici koruyucu katmana sahiptir.. The air-conditioning heat exchange sheet made of this product can be applied to relatively harsh areas and can significantly increase the service life of the air conditioner. Aynı zamanda, Isı değişim plakasının korozyon direncinin iyileştirilmesi nedeniyle, yüzey korozyon tozu oluşumu büyük ölçüde azalır, böylece havalandırma kalitesini artırır ve klimalı odadaki havayı arındırır.
Hidrofobik alüminyum folyoya su geçirmez alüminyum folyo da denir, ve yüzey özellikleri hidrofilik alüminyum folyonun tam tersidir. Yani, yoğunlaşan su alüminyum folyonun yüzeyinde yoğunlaştığında, the contact angle with the aluminum foil is relatively large, genel olarak 75. the above. Açı ne kadar büyük olursa, su iticiliği ne kadar iyi olursa. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, yani, Isı değişim kanatçıkları arasında yoğuşmuş suyun kalmasını önlemek için. The difference is that the hydrophobic aluminum foil achieves the purpose of removing the condensed water between the heat exchange fins by increasing the contact angle between the condensate water and the heat exchange fins, so that the condensate water forms droplets that are easy to slide down.
In the process of processing and manufacturing air-conditioning heat exchange fins, lubricating oil is generally added to the surface, daha sonra delme ve flanşlama, and finally trichloroethylene is used to wash off the lubricating oil. Trikloroetilen insan vücuduna zararlı olduğundan, bu süreci azaltmak için, a self-lubricating aluminum foil is produced accordingly. Adından da anlaşılacağı gibi, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, ve delme sırasındaki yağlama, alüminyum folyonun yüzeyindeki ön işleme tabi tutulmuş film tarafından karşılanır. Yağlama yağı ilavesine gerek olmadığından, the subsequent cleaning and drying process of trichloroethylene is omitted.
The anti-mold aluminum foil is mainly used for the indoor unit of the air die. Its main function is to prevent the surface of the heat exchange fins from being moldy due to use or storage for a long time, thereby significantly improving the air conditioning quality and preventing abnormal odors. Improve the air-conditioned indoor environment.
