Air-conditioning is indispensable to escape the heat in summer. Habang pumapasok ang aircon sa libu libong kabahayan, patuloy din itong umuunlad. Sa kasalukuyan, Ang mga air conditioner ay unti unting umuunlad sa direksyon ng miniaturization, mataas na kahusayan, at mahabang buhay. 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 at 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. Ngayon, 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. Kasabay nito, it needs high strength, magandang ductility, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. Gayunpaman, 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. Sa bayan ko 10 ilang taon na ang nakalipas, and about 15 ilang taon na ang nakalipas, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. Kahit sa kasalukuyan, tungkol sa 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, habang nasa bansa ko, ang ratio na ito ay tungkol sa 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 mga taon. Sa bayan ko, ang paggamit ng pinahiran aluminyo foil ay hindi lalampas 10 mga taon.
Ang ibabaw ng produkto ng aluminyo foil na lumalaban sa kaagnasan ay may isang tiyak na anti kaagnasan proteksiyon layer. 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. Kasabay nito, dahil sa pagpapabuti ng kaagnasan paglaban ng init exchange sheet, ang henerasyon ng ibabaw kaagnasan pulbos ay lubhang nabawasan, sa gayon ay mapabuti ang kalidad ng bentilasyon at pagdalisay ng hangin sa naka air condition na kuwarto.
Ang hydrophobic aluminum foil ay tinatawag ding water repellent aluminum foil, at ang mga katangian ng ibabaw nito ay kabaligtaran lamang ng hydrophilic aluminum foil. Iyan ay, kapag ang condensed water condenses sa ibabaw ng aluminum foil, the contact angle with the aluminum foil is relatively large, sa pangkalahatan 75. the above. Mas malaki ang anggulo, mas maganda ang water repellency. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, na ang ibig sabihin ay, upang maiwasan ang tubig na kondensada mula sa natitirang sa pagitan ng mga palikpik ng palitan ng init. 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, tapos pagsuntok at pagkikiskisan, and finally trichloroethylene is used to wash off the lubricating oil. Dahil ang trichloroethylene ay nakakapinsala sa katawan ng tao, upang mabawasan ang prosesong ito, a self-lubricating aluminum foil is produced accordingly. Tulad ng ipinahihiwatig ng pangalan, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, at ang pagpapadulas sa panahon ng pagsuntok ay dinadala ng pre ginagamot film sa ibabaw ng aluminyo foil. Dahil hindi na kailangang magdagdag ng lubricating oil, 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.
