随着科学事业的发展,探求材料内部结构的要求越来越迫切,这也就促进了测试手段的发展。以压汞法来测定多孔材料的孔结构,由于其复现性较好,已成为目前常用方法之一。压汞法的简单原理是:汞不能润湿固体表面,而只有在压力作用下,汞才能波压入材料的孔隙中,孔径越小所需的压力也就越 With the development of scientific undertakings, the search for the internal structure of materials has become more and more urgent, which has also promoted the development of test methods. The determination of the pore structure of porous materials by mercury porosimetry has been one of the commonly used methods because of its good reproducibility. The simple principle of mercury porosimetry is that mercury does not wet the solid surface, but only under pressure, mercury can wave into the pores of the material, and the smaller the pore size, the greater the pressure required.
