Test methods for aluminium and aluminium alloy foils—Part 5: Determination of wettability
1 Scope
This part of GB/T 22638 specifies the determination method for wettability of aluminium and aluminium alloy foils.
This part is applicable to the determination of wetted parts on the foil surface after annealing.
The wiping method specified in this part is the arbitration method for the wettability determination of aluminium and aluminium alloy foils.
2 Principle
This method uses the principle that different liquids have different wettability on the surface of a fixed material, and uses test solutions with different ratios to detect the foil surface to determine its wettability.
3 Reagents and materials
3.1 Anhydrous ethanol: analytically pure.
3.2 Distilled water.
3.3 Degreasing cotton.
3.4 Forceps.
3.5 Spray bottle.
3.6 Dropper.
3.7 Test solution: take anhydrous ethanol (3.1) and distilled water (3.2) and prepare corresponding test solution according to Table 1.
