測試理論

以某種膜材料為例，將膜用可與其浸潤的液體充分潤濕，由于表面張力的存在，浸潤液將被 束縛在膜的孔隙內(nèi)；給膜的一側(cè)加以逐漸增大的氣體壓強，當氣體壓強達到大于某孔徑內(nèi)浸潤液的表面張力產(chǎn)生的壓強時，該孔徑中的浸潤液將被氣體推出；由于孔徑越小，表面張力產(chǎn)生的壓強越高，所以要推出其中的浸潤液所需施加的氣體壓強也越高；同樣，可知，孔徑zui大的孔內(nèi)的浸潤液將首先會被推出，使氣體透過，然后隨著壓力的升高，孔徑由大到小，孔中的浸潤液依次被推出，使氣體透過，直至全部的孔被打開，達到與干膜相同的透過率；

    首先被打開的孔所對應(yīng)的壓力，為泡點壓力，該壓力所對應(yīng)的孔徑為zui大孔徑； 在此過程中，實時記錄壓力和流量，得到壓力-流量曲線；壓力反應(yīng)孔徑大小的信息，流量反應(yīng)某種孔徑的孔的多少的信息；然后再測試出干膜的壓力-流量曲線，可根據(jù)相應(yīng)的公式計算得到該膜樣品的zui大孔徑、平均孔徑、zui小孔徑以及孔徑分布、透過率。

Test theory
In a film material as an example, its liquid infiltration with sufficient wetting of the membrane, due to the existence of surface tension, liquid infiltration will be trapped in the pores of the membrane; to one side of the membrane to gas pressure increases, when the gas pressure reaches the pressure is greater than the surface tension of a liquid infiltration aperture produced inside, the liquid infiltration aperture in gas will be launched; due to the aperture is smaller, the pressure caused by surface tension is high, so to launch liquid infiltration required for gas pressure imposed by the higher; also, the infiltration of liquid within the bore of the maximum aperture will be first introduced, then through the gas. With the increase of pressure, pore size from big to small, the infiltration of liquid hole in order to be launched, the gas through, until all the holes are opened, and achieve the same transmittance of dry film;
The first open hole pressure for bubble pressure, pore size corresponding to the pressure for maximum pore size; in this process, real-time recording of pressure and flow, pressure flow curve; pressure reaction pore size of the information flow, a reaction pore number information; and then a dry test the film pressure flow curve, maximum pore size, according to the corresponding formula of the membrane samples the average pore size, pore size and pore size distribution, the minimum transmission rate.
