摘要
The paper describes the development and operation of an instrument that can measure the flow rate of penetrants through the capillary structure of wood. The instrument was tested with aspen wood (sapwood and heartwood) and several surfactants, either individually or in blends. The results of the penetration measurements, precise and repeatable, showed that only the slower penetration of aspen heartwood could be improved with selected blends of surfactants, as surfactants could not improve the already fast penetration of the black spruce wood and aspen sapwood. Experiments in a pulping pilot-plant strongly supported the results obtained by the penetration instrument.
