测试理论

以某种膜材料为例，将膜用可与其浸润的液体充分润湿，由于表面张力的存在，浸润液将被 束缚在膜的孔隙内；给膜的一侧加以逐渐增大的气体压强，当气体压强达到大于某孔径内浸润液的表面张力产生的压强时，该孔径中的浸润液将被气体推出；由于孔径越小，表面张力产生的压强越高，所以要推出其中的浸润液所需施加的气体压强也越高；同样，可知，孔径zui大的孔内的浸润液将首先会被推出，使气体透过，然后随着压力的升高，孔径由大到小，孔中的浸润液依次被推出，使气体透过，直至全部的孔被打开，达到与干膜相同的透过率；

    首先被打开的孔所对应的压力，为泡点压力，该压力所对应的孔径为zui大孔径； 在此过程中，实时记录压力和流量，得到压力-流量曲线；压力反应孔径大小的信息，流量反应某种孔径的孔的多少的信息；然后再测试出干膜的压力-流量曲线，可根据相应的公式计算得到该膜样品的zui大孔径、平均孔径、zui小孔径以及孔径分布、透过率。

Scientific low energy consumption and shape design
Sealed external heat sink
No fan cooling
No risk of producing particles
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.
