Gas Transmission Rate Test System for Films
| Description: |
Gas Transmission Rate Test System, based on the test principle of differential pressure method, is professionally suitable for the determination of gas transmission rate, solubility coefficient, diffusion coefficient and permeability coefficient at varied temperatures of plastic film, containers, composite film, high barrier materials, sheet, metal foil, etc. The test system conforms to GB, ISO, ASTM and other national and international standards. |
| Product Characteristics: |
1. Precise Data
2. Dual-Testing for Film & Container
3. Smart Control
4. Multi-System Connectable
5. Extensive Functions
Low-Carbon & Energy-Saving
|
| Principle: | adopts the test principle of differential pressure method. The prepared sample is placed between the upper and lower test chambers and clamped. Vacuum the low-pressure chamber (lower chamber) and then vacuum the whole system. When achieving specified vacuum degree, close the lower chamber and fill the upper chamber (high-pressure chamber) with test gas at a certain pressure. Ensure a constant pressure difference (adjustable) is formed on both sides of the sample. The gas will permeate from the high-pressure side to the low-pressure side under the differential pressure gradient. Thus, by analyzing the internal pressure on the low-pressure side, the barrier parameters of the sample can be obtained. |
