Product Description

Product Description

Scope of application:
The differential pressure gas permeability tester is based on the test principle of the differential pressure method. It is a gas permeability tester professionally used for film samples. It is suitable for the determination of gas permeability and gas permeability coefficient of plastic films, composite films, high barrier materials, sheets, and metal foils at various temperatures.
Basic applications:
1. Suitable for gas permeability test of various plastic films, plastic composite films, paper-plastic composite films, co-extruded films, aluminized films, aluminum foils, aluminum foil composite films and other film materials.
2. Suitable for gas permeability test of various sheet materials such as engineering plastics, rubber, building materials, such as PP sheets, PVC sheets, PVDC sheets, etc.
Extended applications:
1. Suitable for permeability test of various gases, such as oxygen, carbon dioxide, nitrogen, air, helium, etc.
2. Suitable for barrier performance test of various films to flammable and explosive gases.
3. Suitable for gas permeability test of biodegradable films, such as starch biodegradable bags, etc.
4. Suitable for gas permeability test of aerospace materials, such as helium permeability test of airship airbags.
5. Suitable for gas permeability test of composite materials such as paper and paper-plastic, such as cigarette aluminum foil, Tetra Pak packaging sheets, instant noodle paper bowls, disposable paper cups, etc.
6. Suitable for gas permeability test of paint film coated on substrate.
7. Suitable for air permeability testing of glass fiber cloth, glass fiber paper and other materials, such as varnished cloth, high temperature cloth, fluorine silicone cloth, etc.
8. Suitable for gas permeability testing of various cosmetic hoses, aluminum-plastic tubes, and toothpaste tube sheets.
9. Suitable for air permeability testing of various rubber sheets, such as automobile tire air permeability testing.

Product features:
1. The gas permeation rate, gas permeation coefficient, solubility coefficient and diffusion coefficient of the sample can be measured simultaneously.
2. The three test chambers can be tested completely independently.
3. Wide range and high-precision temperature control can meet the test under various test conditions.
4. Three test process judgment modes are provided: proportional mode, fuzzy mode and time mode.
5. The test range can be expanded as needed to meet the requirements of large permeability test.
6. Support the test of toxic gas and flammable and explosive gas (customization is required).
7. Pneumatic clamping of samples is adopted, which is convenient and fast.
8. The system adopts electronic intelligent control, and the whole test process is completed automatically.
9. Standard membrane is provided for rapid calibration to ensure the accuracy of test data.
10. The product complies with GMP multi-level authority.
11. Micro printer, note to print test statistical results at any time.
12. Special computer communication software can display the test in real time and analyze and process the data, and save the data.
13. Equipped with USB universal data interface for convenient data transmission.

Test principle
The instrument adopts the differential pressure test principle, and the pre-processed sample is placed between the upper and lower test chambers and clamped. First, the low-pressure chamber (lower chamber) is vacuumed, and then the entire system is evacuated; when the specified vacuum degree is reached, the lower test chamber is closed, and a certain pressure of test gas is filled into the high-pressure chamber (upper chamber), and a constant pressure difference (adjustable) is formed on both sides of the sample; in this way, the gas will penetrate from the high-pressure side to the low-pressure side under the action of the pressure gradient, and the various barrier parameters of the tested sample can be obtained by monitoring the pressure inside the low-pressure side.

Test standards:
The instrument complies with many national and international standards: GB/T 1038 , ISO 15105-1 , ISO 2556 , ASTM D1434 , JIS K7126-1 , YBB00082003
