摘要：
A method of determination has been developed for comparative characterization of the particle penetration and dust storage capacity of surface-treated needle felts. This method is based on transmitted light and reflected light microscopy used in combination with specially developed image analysis software with which it is possible to determine the two-dimensional surface porosity and the pore depth distribution at the surface of the filter medium. Two straight calibration lines are obtained when the surface porosity measurements are combined with filter test results that conform to the VDI (Confederation of German Industry) guidelines, such as average clean gas dust concentration and mass of residual dust. These two straight calibration lines can be used to estimate the particle penetration and the dust storage capacity of different surface-treated needle felts.
