Aluminum corrosion resistance is mainly reflected in what areas?
Third heat-resistant properties, that at a certain temperature, a certain humidity place a long time corrosion sex. The performance is also an important indicator to measure the heat transfer sheet weathering capabilities.
The second is resistant to salt spray corrosion test conditions generally in the 35 oC, 3% salt spray environment requires 500 hours can not have spots of corrosion. Salt spray corrosion resistance is directly related to the heat transfer sheet length of life. In coastal areas, due to the high salt content in the air, so the heat transfer sheet of salt spray corrosion resistance have high requirements;
Corrosion resistance is mainly reflected in three aspects: First, alkali resistance, since the surface of lubricating oil required alkaline cleaner to remove the punched sheet after the heat exchanger, the functional requirements of the aluminum foil surface coating must have a certain alkali resistance generally requires soaking in a 20% NaOH solution for 3 minutes without blistering;
