Air-conditioning is indispensable to escape the heat in summer. À medida que o ar condicionado entra em milhares de lares, também está em constante desenvolvimento. Atualmente, os condicionadores de ar estão se desenvolvendo gradualmente na direção da miniaturização, alta eficiência, e longa vida. 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 e 0.15 milímetros. 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. Ao mesmo tempo, it needs high strength, boa ductilidade, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. No entanto, 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, alto, 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. No meu país 10 anos atrás, and about 15 anos atrás, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. Mesmo atualmente, sobre 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, enquanto estiver no meu país, essa proporção é sobre 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 anos. No meu país, o uso de folha de alumínio revestida não excede 10 anos.
A superfície do produto de folha de alumínio resistente à corrosão possui uma certa camada protetora anticorrosiva. 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. Ao mesmo tempo, devido à melhoria da resistência à corrosão da folha de troca de calor, a geração de pó de corrosão superficial é bastante reduzida, melhorando assim a qualidade da ventilação e purificando o ar na sala com ar condicionado.
A folha de alumínio hidrofóbica também é chamada de folha de alumínio repelente à água, e suas propriedades de superfície são exatamente o oposto das folhas de alumínio hidrofílicas. Aquilo é, quando a água condensada condensa na superfície da folha de alumínio, the contact angle with the aluminum foil is relatively large, geralmente 75. the above. Quanto maior o ângulo, melhor será a repelência à água. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, aquilo é, para evitar que água condensada permaneça entre as aletas de troca de calor. 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, então perfurando e flangeando, and finally trichloroethylene is used to wash off the lubricating oil. Como o tricloroetileno é prejudicial ao corpo humano, para reduzir esse processo, a self-lubricating aluminum foil is produced accordingly. Como o nome implica, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, e a lubrificação durante a perfuração é suportada pelo filme pré-tratado na superfície da folha de alumínio. Como não há necessidade de adicionar óleo lubrificante, 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.
