Foreword
GB/T 22638 "aluminum foil test method" is divided into 10 parts.
- Part 1. Determination of thickness;
- Part 2. Detection of pinholes;
- Part 3. Detection of adhesion;
- Part 4. Determination of surface wetting tension;
- Part 5. Detection of wettability;
- Part 6. Determination of DC resistance;
- Part 7. Determination of heat seal strength;
- Part 8. Determination of texture content;
- Part 9. Hydrophilic testing;
Part 10. Determination of the surface density of the coating.
This part is part 5 of GB/T 22638.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This part of the replacement GB/T 22638.5-2008 "aluminum foil test method Part 5. brush water test method", and GB/T 22638.5-
2008, the main technical changes are as follows.
- Change the standard name to "Aluminum foil test method Part 5. Detection of wetting";
--- increase the "spray method" and "drip method" two kinds of wetting detection method;
--- should be checked before removing the outer layer of foil thickness modified to 3mm;
--- increase the "if the foil directly on the wetting test, should prevent the test solution pollution foil face" requirements;
--- increase the "do not allow the same area in the foil area for repeated testing" requirements.

Aluminum foil test method
Part 5. Detection of wettability
1 Scope
This part of GB/T 22638 specifies the method of testing the wettability of aluminum foil.
This part is suitable for the detection of wettability of aluminum foil after annealing.
The wiping method specified in this section is the arbitration method for aluminum foil wettability testing.
2 principle of the method
The method uses different liquid in a fixed material surface wetting different principle, with different ratio of the test solution to detect the surface of aluminum foil to determine
The wettability of the surface of the aluminum foil.
3 reagents and materials
3.1 anhydrous ethanol, analytical grade.
3.2 Distilled water.
3.3 absorbent cotton.
3.4 Tweezers.
3.5 spray bottle.
3.6 dropper.
3.7 test solution. take ethanol (3.1) and distilled water (3.2), according to Table 1 preparation of the corresponding test solution.
Table 1 test solution ratio
Test solution No. test solution
1 distilled water (3.2)
2 ethanol solution (1 9)
3 Ethanol solution (2 8)
4 ethanol solution (3 7)
5 Ethanol solution (4 6)
6 ethanol solution (5 5)
7 ethanol solution (6 4)
8 Ethanol solution (7 3)
4 test conditions
The test shall be carried out at room temperature and the foil temperature shall not be 5 ° C or higher above 5 ° C above room temperature.
