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 3 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 22638.3-2008 "aluminum foil test method Part 3. determination of adhesion", and GB/T 22638.3- 2008, the main technical changes are as follows. --- will be removed before the detection of aluminum foil roll layer thickness is modified to 3mm; --- increase the "local test method" for the thickness of not more than 0.05mm, the width of more than 800mm annealing state aluminum foil edge or Bureau Detection of adhesion between layers and layers; - the "average value of the test result of the three volumes of the sample as the detection value of the adhesion" was deleted.

1 Scope

This part of GB/T 22638 specifies the principle, test conditions, sampling, and inspection methods of the inspection method for the adhesion of aluminum foil. Part of the detection method, the results that the test report. The overall inspection method specified in this section shall apply to the arbitration inspection of the adhesion of aluminum foil with annealing thickness of not more than 0.05mm. The local inspection method specified in this section shall apply to the edge of aluminum foil with an thickness of not more than 0.05mm and a width of more than 800mm. Local layer and interlayer adhesion test.

2 principle of the method

The aluminum foil is peeled off manually to measure the minimum shedding length L required for the natural peeling of the dropping weight of the aluminum foil by the peeled portion (as shown in Fig. 1 ), And the degree of adhesion between the aluminum foil layer and the layer was evaluated with this length. Description. OA, O1A1 --- through the axis of the horizontal line; L --- aluminum foil peel off part of the shedding length. Figure 1 Schematic diagram of the overall detection method

3 test conditions

The test shall be carried out at room temperature and the temperature of the foil shall not be 5 ° C or higher above 5 ° C above room temperature. ......
