Air-conditioning is indispensable to escape the heat in summer. Þar sem loftkæling fer inn í þúsundir heimila, það er líka í stöðugri þróun. Sem stendur, loftræstingar eru smám saman að þróast í átt að smækningu, mikil afköst, og langt líf. 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 og 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. Í dag, 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. Á sama tíma, it needs high strength, góð sveigjanleiki, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. Hins vegar, 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, hátt, 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. Í mínu landi 10 fyrir mörgum árum, og um 15 fyrir mörgum árum, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. Jafnvel í augnablikinu, um 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, meðan ég er í mínu landi, þetta hlutfall er um 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 ár. Í mínu landi, notkun húðaðrar álpappírs fer ekki yfir 10 ár.
Yfirborð tæringarþolinnar álpappírsvöru hefur ákveðið tæringarvarnarlag. 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. Á sama tíma, vegna endurbóta á tæringarþol hitaskiptaplötunnar, myndun yfirborðs tæringardufts minnkar verulega, þar með bæta loftræstingargæði og hreinsa loftið í loftkælda herberginu.
Vatnsfælin álpappír er einnig kallaður vatnsfráhrindandi álpappír, og yfirborðseiginleikar þess eru einmitt andstæðar vatnssækinni álpappír. Það er, þegar þétta vatnið þéttist á yfirborði álpappírsins, the contact angle with the aluminum foil is relatively large, almennt 75. the above. Því stærra hornið, því betra er vatnsfráhrindingin. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, það er, til að koma í veg fyrir að þétt vatn verði eftir á milli hitaskiptaugganna. 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, síðan kýla og flengja, and finally trichloroethylene is used to wash off the lubricating oil. Þar sem tríklóretýlen er skaðlegt mannslíkamanum, til að draga úr þessu ferli, a self-lubricating aluminum foil is produced accordingly. Eins og nafnið gefur til kynna, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, og smurningin við gata er borin af formeðhöndluðu filmunni á yfirborði álpappírsins. Þar sem engin þörf er á að bæta við smurolíu, 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.
