Air-conditioning is indispensable to escape the heat in summer. ໃນຂະນະທີ່ເຄື່ອງປັບອາກາດເຂົ້າໄປໃນເຮືອນຫຼາຍພັນຄົນ, ມັນຍັງພັດທະນາຢ່າງຕໍ່ເນື່ອງ. ປັດຈຸບັນ, ເຄື່ອງປັບອາກາດແມ່ນຄ່ອຍໆພັດທະນາໃນທິດທາງຂອງ miniaturization, ປະສິດທິພາບສູງ, ແລະຊີວິດຍາວ. 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 ແລະ 0.15 ມມ. 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. ໃນເວລາດຽວກັນ, it needs high strength, ductility ດີ, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. ແນວໃດກໍ່ຕາມ, 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, ສູງ, 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. ໃນປະເທດຂອງຂ້ອຍ 10 ປີກ່ອນ, ແລະກ່ຽວກັບ 15 ປີກ່ອນ, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. ເຖິງແມ່ນວ່າໃນປັດຈຸບັນ, ກ່ຽວກັບ 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, ໃນຂະນະທີ່ຢູ່ໃນປະເທດຂອງຂ້ອຍ, ອັດຕາສ່ວນນີ້ແມ່ນກ່ຽວກັບ 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 ປີ. ໃນປະເທດຂອງຂ້ອຍ, ການນໍາໃຊ້ແຜ່ນອາລູມິນຽມເຄືອບບໍ່ເກີນ 10 ປີ.
ດ້ານຂອງຜະລິດຕະພັນແຜ່ນອາລູມິນຽມທີ່ທົນທານຕໍ່ການກັດກ່ອນມີຊັ້ນປ້ອງກັນການກັດກ່ອນທີ່ແນ່ນອນ. 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. ໃນເວລາດຽວກັນ, ເນື່ອງຈາກການປັບປຸງການຕໍ່ຕ້ານ corrosion ຂອງແຜ່ນແລກປ່ຽນຄວາມຮ້ອນ, ການຜະລິດຝຸ່ນ corrosion ດ້ານແມ່ນຫຼຸດລົງຢ່າງຫຼວງຫຼາຍ, ດັ່ງນັ້ນ, ປັບປຸງຄຸນນະພາບການລະບາຍອາກາດແລະເຮັດຄວາມສະອາດອາກາດໃນຫ້ອງເຄື່ອງປັບອາກາດ.
ແຜ່ນອາລູມິນຽມ hydrophobic ຍັງເອີ້ນວ່າ foil ອາລູມິນຽມນ້ໍາ, ແລະຄຸນສົມບັດດ້ານຂອງມັນແມ່ນກົງກັນຂ້າມກັບແຜ່ນອາລູມິນຽມ hydrophilic. ນັ້ນແມ່ນ, ໃນເວລາທີ່ນ້ໍາຂົ້ນ condenses ເທິງຫນ້າດິນຂອງແຜ່ນອາລູມິນຽມ, the contact angle with the aluminum foil is relatively large, ໂດຍທົ່ວໄປ 75. the above. ມຸມທີ່ໃຫຍ່ກວ່າ, ການກັນນ້ໍາທີ່ດີກວ່າ. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, ນັ້ນແມ່ນ, ເພື່ອປ້ອງກັນບໍ່ໃຫ້ນ້ໍາຂົ້ນທີ່ເຫລືອຢູ່ລະຫວ່າງ fins ແລກປ່ຽນຄວາມຮ້ອນ. 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, ຫຼັງຈາກນັ້ນ, punching ແລະ flanging, and finally trichloroethylene is used to wash off the lubricating oil. ເນື່ອງຈາກວ່າ trichlorethylene ເປັນອັນຕະລາຍຕໍ່ຮ່າງກາຍຂອງມະນຸດ, ເພື່ອຫຼຸດຜ່ອນຂະບວນການນີ້, a self-lubricating aluminum foil is produced accordingly. ດັ່ງທີ່ຊື່ຫມາຍເຖິງ, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, ແລະ lubrication ໃນລະຫວ່າງການ punching ແມ່ນ borne ໂດຍຮູບເງົາທາງສ່ວນຫນ້າຂອງການປິ່ນປົວຢູ່ດ້ານຂອງ foil ອາລູມິນຽມ. ເນື່ອງຈາກວ່າບໍ່ຈໍາເປັນຕ້ອງເພີ່ມນ້ໍາມັນຫລໍ່ລື່ນ, 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.
