Air-conditioning is indispensable to escape the heat in summer. 수천 가구에 에어컨이 설치되면서, 또한 지속적으로 발전하고 있습니다.. 현재, 에어컨은 점차 소형화 방향으로 발전하고 있습니다., 고효율, 그리고 장수. 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 그리고 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. 동시에, it needs high strength, 좋은 연성, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. 하지만, 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, 높은, 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. 내 나라에서는 10 여러 해 전에, 그리고 약 15 여러 해 전에, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. 현재에도, ~에 대한 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, 내 나라에 있는 동안, 이 비율은 대략 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 연령. 내 나라에서는, 코팅된 알루미늄 호일의 사용은 다음을 초과하지 않습니다. 10 연령.
부식 방지 알루미늄 호일 제품의 표면에는 특정 부식 방지 보호 층이 있습니다.. 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. 동시에, 열교환시트의 내식성 향상으로 인해, 표면 부식분의 발생이 대폭 감소됩니다., 이를 통해 환기 품질을 향상시키고 에어컨이 설치된 실내의 공기를 정화합니다..
소수성 알루미늄박은 발수성 알루미늄박이라고도 불립니다., 표면 특성은 친수성 알루미늄 호일과 정반대입니다.. 그건, 알루미늄 호일 표면에 응축수가 응결할 때, the contact angle with the aluminum foil is relatively large, 일반적으로 75. the above. 각도가 클수록, 발수성이 좋을수록. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, 그건, 열교환 핀 사이에 응축수가 남지 않도록. 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, 그런 다음 펀칭 및 플랜징, and finally trichloroethylene is used to wash off the lubricating oil. 트리클로로에틸렌은 인체에 유해하기 때문에, 이 과정을 줄이기 위해, a self-lubricating aluminum foil is produced accordingly. 이름에서 알 수 있듯이, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, 펀칭 중 윤활은 알루미늄 호일 표면의 전처리 필름에 의해 수행됩니다.. 윤활유를 첨가할 필요가 없기 때문에, 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.
