The key indicators of Air-Conditioner Foil

Coil Coating Aluminium was conducted around the basis on the Air-Conditioner Foil after surface treatment, and in addition to the ought to the requirements on the high grade aluminum, such as chemical composition, mechanical properties and geometry size performance indicators, coating aluminum foil also must has great plate kind and coating properties.

(one), coating adhesion: coating adhesion is indicator of Aluminium Foil Roll and its surface coating adhesive fastness. In the event the coating adhesion is as well modest, then in additional processing and use of the coating aluminum foil the surface film of it is going to fall off easily, and hence seriously impacts the weight on the coating aluminum foil, so as a result it calls for coating adhesion to become better. Normally only qualitatively the coating adhesion test, the key test approach of friction resistance test, the test and cup drawing technique, and so forth.

(two), the hydrophilic house of Coated Aluminum Coil: right after a time frame hydrophilic aluminum foil becoming in use, due to numerous environmental elements along with the impact on the surface hydrophilicity, it may be affected. Consequently, hydrophilic property might be usually divided into early hydrophilic property and hydrophilic property after environmental test. The common of the hydrophilic home mostly is measured by the size of a horn. It can be calculated by a particular volume of water droplets within the location on the surface from the aluminum foil size.

(three), corrosion resistance:Corrosion resistance of Aluminum Foil China is mainly manifested in 3 aspects: one particular will be the alkali resistance. Due to the surface from the lubricating oil must use alkaline cleaner to remove, so it demands function coating around the surface of the aluminum foil must have certain alkali resistance, general essential not to play bubbles following being socked in 20% NaOH resolution; Second, salt fog, typically implies that inside the test situations of 3% salt spray environment of 35 oC, it needs its corrosion resistance cannot have corrosion spots for 500 hours. The good quality of salt fog corrosion resistance is straight related to the length of service life. In coastal places, because of the higher salt content in the air, you will find larger needs for the salt fog corrosion resistance of heat-exchange piece; Third, it truly is wet and heat resistance, that namely within a specific temperature, the corrosion resistance of certain humidity that has been stored to get a lengthy period. The efficiency is also measured in hot weather resistant capacity of a vital indicator.
