The main indicators of Air-Conditioner Foil

Coil Coating Aluminium was carried out on the basis on the Air-Conditioner Foil right after surface therapy, and in addition to the have to the requirements around the higher grade aluminum, like chemical composition, mechanical properties and geometry size performance indicators, coating aluminum foil also must has excellent plate sort and coating properties. 
(1), coating adhesion: coating adhesion is indicator of Aluminium Foil Roll and its surface coating adhesive fastness. If the coating adhesion is too modest, then in further processing and use from the coating aluminum foil the surface film of it's going to fall off easily, and therefore seriously impacts the weight of the coating aluminum foil, so as a result it requires coating adhesion to be better. Generally only qualitatively the coating adhesion test, the key test strategy of friction resistance test, the test and cup drawing approach, etc. 
(2), the hydrophilic house of Coated Aluminum Coil: soon after a time period hydrophilic aluminum foil being in use, as a result of numerous environmental aspects and also the impact in the surface hydrophilicity, it can be affected. Consequently, hydrophilic home may be generally divided into early hydrophilic property and hydrophilic home after environmental test. The common from the hydrophilic house mainly is measured by the size of a horn. It may be calculated by a specific volume of water droplets inside the location on the surface on the aluminum foil size. 
(3), corrosion resistance:Corrosion resistance of Aluminum Foil China is mostly manifested in 3 aspects: 1 is the alkali resistance. Due to the surface on the lubricating oil need to use alkaline cleaner to remove, so it demands function coating around the surface on the aluminum foil need to have particular alkali resistance, basic needed to not play bubbles right after getting socked in 20% NaOH resolution; Second, salt fog, usually means that in the test circumstances of 3% salt spray environment of 35 oC, it calls for its corrosion resistance can not have corrosion spots for 500 hours. The quality of salt fog corrosion resistance is straight related to the length of service life. In coastal locations, as a result of the high salt content in the air, you can find higher specifications for the salt fog corrosion resistance of heat-exchange piece; Third, it really is wet and heat resistance, that namely within a certain temperature, the corrosion resistance of specific humidity that has been stored for a extended period. The performance can also be measured in hot weather resistant capacity of a vital indicator.
