The primary indicators of Air-Conditioner Foil

Coil Coating Aluminium was conducted around the basis of the Air-Conditioner Foil right after surface remedy, and as well as the ought to the needs on the higher grade aluminum, for example chemical composition, mechanical properties and geometry size overall performance indicators, coating aluminum foil also should has very good plate kind and coating properties.

(one), coating adhesion: coating adhesion is indicator of Aluminium Foil Roll and its surface coating adhesive fastness. When the coating adhesion is also tiny, then in additional processing and use on the coating aluminum foil the surface film of it's going to fall off simply, and as a result seriously impacts the weight on the coating aluminum foil, so for that reason it demands coating adhesion to be better. Typically only qualitatively the coating adhesion test, the principle test strategy of friction resistance test, the test and cup drawing approach, etc.

(two), the hydrophilic home of Coated Aluminum Coil: after a period of time hydrophilic aluminum foil being in use, because of numerous environmental aspects as well as the impact on the surface hydrophilicity, it can be affected. For that reason, hydrophilic house might be normally divided into early hydrophilic property and hydrophilic house right after environmental test. The regular of the hydrophilic property mainly is measured by the size of a horn. It can be calculated by a specific volume of water droplets within the region from the surface in the aluminum foil size.

(three), corrosion resistance:Corrosion resistance of Aluminum Foil China is mostly manifested in 3 elements: one particular will be the alkali resistance. On account of the surface of the lubricating oil should use alkaline cleaner to take away, so it demands function coating around the surface in the aluminum foil have to have particular alkali resistance, general essential not to play bubbles following becoming socked in 20% NaOH remedy; Second, salt fog, normally implies that in the test conditions of 3% salt spray atmosphere of 35 oC, it calls for its corrosion resistance cannot have corrosion spots for 500 hours. The top quality of salt fog corrosion resistance is straight associated with the length of service life. In coastal areas, because of the higher salt content material within the air, you will find larger specifications for the salt fog corrosion resistance of heat-exchange piece; Third, it really is wet and heat resistance, that namely inside a particular temperature, the corrosion resistance of particular humidity which has been stored to get a lengthy period. The overall performance can also be measured in hot climate resistant capacity of a vital indicator.
