多孔材料孔率的测定方法

Determining Methods for Porosity of Porous Materials

摘要:

孔率是多孔材料的关键指标，是多孔材料若干性能最主要的决定性因素。简单介绍了测定多孔材料孔率的几种常用方法，包括显微分析法、质量．体积直接计算法、浸泡介质法、漂浮法和压汞法等。

Abstract:

Porosity, a key index of porous materials, is the most primary factor for many properties of porous materials. Some common methods are introduced for determining the porosity of porous materials, including the microscopic analysis, the mass-volume direct calculation, the medium soak, the flotage method, the mercury method and so on.
