gas permeability tester for Organosilicone film - 1

Test Method for Organosilicon Film Gas Permeability Abstract: Organosilicone film is a new type of polymer material with excellent performance. The gas permeability is an important factor affecting the application of organosilicone film. In this paper, the principle of differential pressure method is used to measure the carbon dioxide transmission of a kind of organosilicone film, and the test principle, equipment parameters, application scope, test process and other contents are introduced, which provides a reference for the test of other gas barrier properties of organosilicone film. Keywords: organosilicone film, carbon dioxide transmission rate, differential pressure gas permeability tester, permeability, differential pressure method Organosilicon film is a type of semi-inorganic and semi-organic polymer material. It has good heat resistance, low-temperature flexibility, high dielectric strength, chemical inertness, permeability and selective permeability. It can be applied in electronic skin, intelligent sensor, functional packaging, protective film, wound dressing, scar paste, gas separation film in electronic, agriculture, manufacturing, pharmaceutical industry and other fields. In the above applications of organosilicone film, gas permeability is an important factor affecting the application effect of the film. For example, wound dressing with good permeability is conducive to wound healing, and good permeability selectivity is conducive to improving the separation effect of the separation membrane. The permeability of the organosilicone film is related to the molecular structure and the morphological structure of the film. Therefore, the test of the permeability of the organosilicone film can provide a data reference for adjusting the production process of the film. Test Sample In this test, a type of organosilicone film is used as the test sample to test the carbon dioxide permeability of the sample. Standard At present, the principle of differential pressure method is mainly used to test the carbon dioxide transmission of flexible plastic packaging materials. The test process is based on ISO 2556 - Plastics -- Determination of the gas transmission rate of films and thin sheets under atmospheric pressure -- Manometric method Test Instrument In this paper, the VAC-V2 Differential Pressure Gas Permeability Tester is used as the test

thickness, test mode, test temperature, humidity and other parameter information on the control software of the instrument, click “test” and switch on the vacuum pump to start the test. The instrument runs the test according to the set parameters, and the test results are displayed after the test. Test Results The results of the three samples were 2.671×105cm3/(m2·24h·0.1MPa), 2.704×105cm3/(m2·24h·0.1MPa) and 2.693×105cm3/(m2·24h·0.1MPa). The arithmetic mean value of the three samples was 2.689×105cm3/(m2·24h·0.1MPa). Conclusion Gas permeability is an important performance index of...
