摘要:ABSTRACT(#br)A technique to determine the permeability from X-ray microtomographic images was developed and applied to paper structures. The images are thresholded and a skeleton of the pore space is obtained from the images. The skeleton is represented by means of a network of r...

摘要:Filtration of submicrometer aerosols in fibrous beds was considered as a mass transfer process. Earlier experimental data on the single-fiber collection efficiency of aerosols collected in fibrous filters were used to calculate j-factors for mass transfer. A correlation for j-fac...

摘要:The drag force acting on particle dendrites attached to spherical collectors was calculated by considering the dendrites as slender bodies. The results were compared with calculations based on a previously developed empirical method and were found to agree with their predictions ...

摘要:Abstract(#br)Some current models for moisture diffusion in paper in the hygroscopic range are analyzed. In general, two types of diffusion models can be recognized. Models of the first type treat paper as a homogeneous medium with moisture flux that is proportional to the gradien...

摘要:The settling of suspensions of slender rod-like particles with large aspect ratios was studied. The novel technique of enhancement of sedimentation rates by the addition of buoyant particle promoters was applied to such suspensions. The settling rates could be increased by many t...

摘要:In the pulp and paper industry, it is often necessary to characterize the drainage capability or a pulp on the paper machines. The industry uses a standard measure called the freeness to represent this and other properties for papermaking pulps.The freeness is the total volume of...

摘要:Abstract(#br)Among the biorefinery processes based on wood resources that are under current development, hemicellulose extraction using aqueous media is one of the prominent ones. The hemicelluloses in wood extracts need to be separated from inhibitory compounds. We examined...

摘要:Abstract(#br)There are convincing results in the literature indicating that the fiber yield for fully bleached hardwood kraft pulps can be increased by approximately 2% (measured on chip weight as basis) by pulping at milder conditions and bleaching under more aggressive con...
