POROSITY AND SKELETAL DENSITY OF FIBER MATERIALS DETERMINED BY MERCURY INTRUSION TECHNIQUE
In pulp and paper technology, measurements of wood porosity and skeletal density are important, for instance to anticipate the liquor impregnation ability in the pulping stage and to build mathematical model. Pore volume, pore size distribution, and skeletal density were studied using mercury-intrusion technique for different fiber materials at present work. Results showed that mercury intrusion is a useful technique for evaluating porous materials. The skeletal density of wood is practically independent of the type of wood species, at least for wood in dry state, and can be approximated as a constant within the range of 1.35-1.40 g/cm3.
