Air-conditioning is indispensable to escape the heat in summer. एअर कंडिशनिंग हजारो घरांमध्ये प्रवेश करते म्हणून, ते देखील सतत विकसित होत आहे. सध्या, एअर कंडिशनर हळूहळू सूक्ष्मीकरणाच्या दिशेने विकसित होत आहेत, उच्च कार्यक्षमता, आणि दीर्घ आयुष्य. 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 आणि 0.15 मिमी. 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. त्याच वेळी, it needs high strength, चांगली लवचिकता, uniform thickness, and good flatness. The standards and alloys of air-conditioning foils are relatively simple and suitable for large-scale production. तथापि, 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. माझ्या देशात 10 वर्षांपूर्वी, and about 15 वर्षांपूर्वी, the aluminum foils used for heat exchangers in air conditioners were all non-coated aluminum foils. सध्या तरी, बद्दल 50% of the heat exchange fins used in developed countries are still uncoated aluminum foil, माझ्या देशात असताना, हे प्रमाण सुमारे आहे 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 वर्षे. माझ्या देशात, लेपित ॲल्युमिनियम फॉइलचा वापर पेक्षा जास्त नाही 10 वर्षे.
गंज-प्रतिरोधक ॲल्युमिनियम फॉइल उत्पादनाच्या पृष्ठभागावर विशिष्ट गंजरोधक संरक्षणात्मक स्तर असतो. 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. त्याच वेळी, हीट एक्सचेंज शीटच्या गंज प्रतिरोधकतेच्या सुधारणेमुळे, पृष्ठभागावरील गंज पावडरची निर्मिती मोठ्या प्रमाणात कमी झाली आहे, त्यामुळे वायुवीजन गुणवत्ता सुधारते आणि वातानुकूलित खोलीतील हवा शुद्ध होते.
हायड्रोफोबिक ॲल्युमिनियम फॉइलला वॉटर-रेपेलेंट ॲल्युमिनियम फॉइल देखील म्हणतात, आणि त्याचे पृष्ठभाग गुणधर्म हायड्रोफिलिक ॲल्युमिनियम फॉइलच्या अगदी उलट आहेत. ते आहे, जेव्हा ॲल्युमिनियम फॉइलच्या पृष्ठभागावर घनरूप पाणी घनीभूत होते, the contact angle with the aluminum foil is relatively large, साधारणपणे 75. the above. कोन जितका मोठा, पाणी तिरस्करणीय चांगले. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, ते आहे, उष्णता विनिमय पंखांमध्ये घनरूप पाणी शिल्लक राहण्यापासून रोखण्यासाठी. 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, नंतर ठोसा आणि flanging, and finally trichloroethylene is used to wash off the lubricating oil. ट्रायक्लोरेथिलीन मानवी शरीरासाठी हानिकारक असल्याने, ही प्रक्रिया कमी करण्यासाठी, a self-lubricating aluminum foil is produced accordingly. नावाप्रमाणेच, self-lubricating aluminum foil does not need to be lubricated separately during its punching process, आणि पंचिंग दरम्यान स्नेहन ॲल्युमिनियम फॉइलच्या पृष्ठभागावर प्री-ट्रीट केलेल्या फिल्मद्वारे केले जाते. स्नेहन तेल घालण्याची गरज नाही म्हणून, 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.
