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 9 of GB/T 22638.
This part is drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 22638.9-2008 "Aluminum foil test method Part 9. Determination of hydrophilicity". This part with
GB/T 22638.9-2008 compared to the main technical changes are as follows.
--- Change the standard name to "Aluminum foil test method Part 9. Hydrophilic detection";
--- increase the normative reference documents;
--- increase the requirements of distilled water;
--- clear the contact angle of the accuracy requirements of the instrument, modify the temperature range of the drying box, clear the accuracy of the vernier caliper
Claim;
--- to remove the original sample content, unified the sample size, an increase of the initial hydrophilic angle, process hydrophilic angle, continuous impregnation hydrophilic angle, dry - wet
Circulating hydrophilic angle sample preparation content;
--- modified contact angle measuring method in the hydrophilic angle of the description, and increase the contact angle diagram;
--- micro-injector method to increase the "tip and hydrophilic foil surface distance of about 10mm" requirement;
--- the micro-injector method of water droplets in the sample on the standing time modified to "40s ~ 60s";
The micro-injector method clarifies the accuracy of the maximum and minimum droplet diameters and increases the average diameter of the droplets.
And then to a decimal point ";
The determination of the initial hydrophilic angle, the determination of the hydrophilic angle of the process, the determination of the continuous immersion hydrophilic angle, the measurement of the hydrophilic angle of the dry-wet cycle
Set content.

Aluminum foil test method
Part 9. Detection of hydrophilicity
1 Scope
This part of GB/T 22638 specifies the method for the detection of the hydrophilicity of coated aluminum foils.
This part applies to the detection of the hydrophilicity of the coated aluminum foil.
The contact angle measuring method specified in this part is the arbitration method for the hydrophilicity of aluminum foil.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
GB/T 6682 Analytical laboratory water specifications and test methods
Representation and Judgment of Numerical Correction Rule and Limit Value of GB/T 8170
3 Principle of the method
The distilled water drops on the surface of the coating, and the water droplets will spread under the action of the surface tension. This method is formed by measuring the formation of water droplets with the coating surface
(I.e., hydrophilic angle) to detect the hydrophilicity of the coating.
4 reagent
4.1 distilled water, should meet the GB/T 6682 laboratory three water requirements.
4.2 No-clean volatile oil.
5 instruments
5.1 contact angle tester, measuring accuracy of 0.1 °.
5.2 blast oven, the temperature can be controlled at 150 ℃ ± 1 ℃.
5.3 beaker, 500mL.
5.4 sink, sink cross-sectional area of 280mm ×.200mm.
5.5 micro-injector, 10 μL.
5.6 vernier caliper, 0mm ~ 100mm, resolution of 0.02mm.
6 Sample preparation
6.1 Initial hydrophilic angle sample
Take three clean and flat samples, the sample size is 100mm × 50mm.
