The primary indicators of air-conditioner foil




Coil Coating Aluminium was carried out around the basis of your Air-Conditioner Foil after surface remedy, and as well as the should the needs on the High Grade Aluminum, such as chemical composition, mechanical properties and geometry size overall performance indicators, coating aluminum foil also must has very good plate variety and coating properties.
(1) Coating adhesion: coating adhesion is indicator of Aluminium Foil Roll and its surface coating adhesive fastness. In the event the coating adhesion is also little, then in further processing and use with the coating aluminum foil the surface film of it will fall off easily, and therefore seriously affects the weight in the coating aluminum foil, so hence it needs coating adhesion to become superior. Normally only qualitatively the coating adhesion test, the primary test strategy of friction resistance test, the test and cup drawing system, and so on.
(two) The hydrophilic property of Coated Aluminum Coil: following a time period hydrophilic aluminum foil becoming in use, as a result of different environmental things and the effect of the surface hydrophilicity, it may be affected. Consequently, hydrophilic home can be commonly divided into early hydrophilic house and hydrophilic house soon after environmental test. The normal of your hydrophilic home primarily is measured by the size of a horn. Measurement of contact angle can choose special contact angle measurement instrument; However it may also be calculated by a particular volume of water droplets within the location with the surface in the aluminum foil size.
(three) Corrosion resistance:
Corrosion resistance of Aluminum Foil China is primarily manifested in 3 elements: one will be the alkali resistance. Because of the surface of your lubricating oil must use alkaline cleaner to take away, so it demands function coating around the surface on the aluminum foil will have to have particular alkali resistance, basic essential to not play bubbles immediately after becoming socked in 20% NaOH resolution; Second, salt fog, typically implies that in the test conditions of 3% salt spray atmosphere of 35 oC, it requires its corrosion resistance can not 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, on account of the high salt content inside the air, you will discover higher needs for the salt fog corrosion resistance of heat-exchange piece; Third, it is actually wet and heat resistance, that namely within a particular temperature, the corrosion resistance of particular humidity which has been stored for any extended period. The overall performance can also be measured in hot climate resistant capacity of an essential indicator.
