The main indicators of air-conditioner foil

Coil Coating Aluminium was performed around the basis of your Air-Conditioner Foil after surface therapy, and in addition to the have to the needs around the Higher Grade Aluminum, for example chemical composition, mechanical properties and geometry size functionality indicators, coating aluminum foil also need to has good plate type 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 also small, then in further processing and use with the coating aluminum foil the surface film of it is going to fall off effortlessly, and thus seriously affects the weight on the coating aluminum foil, so thus it demands coating adhesion to be much better. Typically only qualitatively the coating adhesion test, the primary test method of friction resistance test, the test and cup drawing method, and so on.

(2) The hydrophilic house of Coated Aluminum Coil: right after a time frame hydrophilic aluminum foil becoming in use, due to different environmental aspects and also the effect with the surface hydrophilicity, it can be affected. As a result, hydrophilic property might be commonly divided into early hydrophilic home and hydrophilic home just after environmental test. The common from the hydrophilic home mainly is measured by the size of a horn. Measurement of contact angle can choose unique contact angle measurement instrument; However it may also be calculated by a certain volume of water droplets in the area of the surface on the aluminum foil size.

(3) Corrosion resistance:

Corrosion resistance of Aluminum Foil China is mostly manifested in three elements: a single may be the alkali resistance. Resulting from the surface on the lubricating oil ought to use alkaline cleaner to get rid of, so it demands function coating on the surface of your aluminum foil ought to have specific alkali resistance, general expected to not play bubbles just after becoming socked in 20% NaOH solution; Second, salt fog, usually implies that in the test situations of 3% salt spray environment of 35 oC, it demands its corrosion resistance cannot have corrosion spots for 500 hours. The excellent of salt fog corrosion resistance is straight related to the length of service life. In coastal places, resulting from the higher salt content material inside the air, you can find higher requirements for the salt fog corrosion resistance of heat-exchange piece; Third, it can be wet and heat resistance, that namely within a specific temperature, the corrosion resistance of certain humidity which has been stored to get a extended period. The efficiency can also be measured in hot climate resistant capacity of an important indicator.
