1、 Testing principle:

BeijingThin film permeameter Using the principle of differential pressure testing, the pre processed sample is placed between the upper and lower testing chambers and clamped. Firstly, perform vacuum treatment on the low-pressure chamber (lower chamber), and then evacuate the entire system; After reaching the specified vacuum degree, close the lower chamber of the test, fill the high-pressure chamber (upper chamber) with a certain pressure of test gas, and ensure that a constant pressure difference (adjustable) is formed on both sides of the sample; In this way, the gas will permeate from the high-pressure side to the low-pressure side under the action of the pressure gradient. By monitoring and processing the pressure inside the low-pressure side, various barrier parameters of the tested sample can be obtained
