  • The Influence of the Expansion Process on Pore Size
    PolyGridTM precision-expanded plastics from Dexmet are used in filtration applications requiring membrane support, purification and separation. Designing a precision expanded plastic material with unique characteristics such as pore size, resin type and thickness are critical factors in selecting
  • Measuring Pore Sizes in Walls of Hollow Fiber Membranes by Porometry
    /min sensors, and both ranges were. used. Up to 256 data points were measured over the selected pressure / pore. size range. Results. Measured data of flow versus pressure for wet and dry runs for all four. samples are shown in fig. 3. The mean flow pore sizes were calculated in the. usual manner
  • Estimation of Curvature from micro-CT Liquid-Liquid Displacement Studies with Pore Scale Resolution
    curvature-based and transducer-based capillary pressure measurements, which gives promise for the usage of image-based estimates of Pc in more realistic pore morphologies. However, further investigations are needed to evaluate the currently available curvature measurement methods, in terms of image resolution
  • Choosing the Appropriate Membrane
    . Consider Pore Size: * The pore size of a filter, normally stated in micrometers (um), is determined by the diameter of a particle that is retained by the filter or by a bubble point test. * Pore sizes can be nominal or absolute. * In filtration processes where pore size is too small to determine
  • Using Mercury Intrusion Porosimetry to Characterize Specialty Papers
    Mercury intrusion porosimetry is a useful technique for. the characterization of coated and uncoated papers. Mercury porosimetry can provide structural information. such as pore size distribution, pore volume, percent. porosity, bulk density, and surface area on a wide variety. of porous paper
  • Medical Device Link .
    A line of customizable expanded polytetrafluoroethylene materials is available for medical and laboratory uses. The Poro-Tex materials support a wide variety of applications, from venting media and microfiltration to analytical equipment. Poro-Tex membranes are available in pore sizes from 5
  • Isotropic Forming of Porous Structures via Metal Injection Molding
    , 9]. Pore sizes in the 0.5-200 µm range are used in the filter. industry, while a pore radius in the 100-500 µm range is important for proper bone ingrowths in. joint replacement applications. In heat transfer systems, porous metals have a broad range of. pore size, starting at less than 2 µm
  • An Introduction To The Physical Characterization of Materials by Mercury (.pdf)
    . The Distribution of Pore Cavity Sizes Associated With a Pore Throat Size. Material Permeability and the Conductivity Formation Factor. Pore Fractal Dimensions. 2. INTRODUCTION. Mercury intrusion porosimetry is one of only a few analytical techniques that permits an analyst to. acquire data over
