Air-conditioning is indispensable to escape the heat in summer. Mientras el aire acondicionado llega a miles de hogares, también está en constante desarrollo. Actualmente, Los acondicionadores de aire se están desarrollando gradualmente hacia la miniaturización., alta eficiencia, y larga 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 y 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. Al mismo tiempo, it needs high strength, buena ductilidad, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. Sin embargo, 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. En mi país 10 hace años que, and about 15 hace años que, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. Incluso en la actualidad, acerca de 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, mientras en mi pais, esta proporción es aproximadamente 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 años. En mi país, el uso de papel de aluminio recubierto no excede 10 años.
La superficie del producto de papel de aluminio resistente a la corrosión tiene una cierta capa protectora anticorrosión.. 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. Al mismo tiempo, debido a la mejora de la resistencia a la corrosión de la lámina de intercambio de calor, la generación de polvo de corrosión superficial se reduce considerablemente, mejorando así la calidad de la ventilación y purificando el aire en la habitación con aire acondicionado.
El papel de aluminio hidrofóbico también se llama papel de aluminio repelente al agua., y sus propiedades superficiales son justo lo contrario del papel de aluminio hidrofílico. Eso es, cuando el agua condensada se condensa en la superficie del papel de aluminio, the contact angle with the aluminum foil is relatively large, generalmente 75. the above. Cuanto mayor sea el ángulo, mejor será la repelencia al agua. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, eso es, para evitar que quede agua condensada entre las aletas de intercambio 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, luego perforar y rebordear, and finally trichloroethylene is used to wash off the lubricating oil. Dado que el tricloroetileno es perjudicial para el cuerpo humano., para reducir este proceso, a self-lubricating aluminum foil is produced accordingly. Como su nombre indica, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, Y la lubricación durante el punzonado corre a cargo de la película pretratada en la superficie del papel de aluminio.. Dado que no es necesario agregar aceite lubricante, 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.
