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. Determination of hydrophilicity; Part 10. Determination of the surface density of the coating. This part is part 4 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 22638.4-2008 "Aluminum foil test method Part 4. Determination of surface wetting tension", and GB/T 22638.4-2008 compared to the main technical changes are as follows. --- modified the test solution ratio of Table 1; The surface wetting tension value corresponding to the test solution No. 30 in Table 2 was changed from 66 to 65; --- will be removed before the detection of aluminum foil roll layer thickness is modified to 3mm; --- increase the "up to pen" surface wetting tension measurement method; --- increase the "if the foil directly on the surface wetting tension determination, should prevent the test solution pollution aluminum foil surface" requirements; --- increased the "not in the same area on the aluminum foil for repeated testing" requirements.

1 Scope

This part of GB/T 22638 specifies the principle, reagents and materials for the determination of the wettability of aluminum foil surfaces, test conditions, sampling, wiping Wipes, dynasty pen and test report. This part is applicable to the determination of wetting tension on aluminum foil surface. The wiping method specified in this part is the arbitration method for the determination of wetting tension on aluminum foil.

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 measure The wetting tension of the aluminum foil surface.
