Journal of Pulp and Paper Science (J PULP PAP SCI)

Publisher: Canadian Pulp and Paper Association. Technical Section

Journal description

The Journal of Pulp and Paper Science (JPPS) is a quarterly publication devoted to the science of pulp and paper. Its aim is to publish articles that illuminate the underlying scientific principles of the technology of pulp and paper rather than those that are of a purely technological or engineering nature. JPPS is published by the Pulp and Paper Technical Association of Canada (PAPTAC).

    ABSTRACT: Methods combining micro scale resolution x-ray shadowgraphs, computerised x-ray micro-tomography and advanced image analysis were developed to study connections between the structure of void space and raw edge imbibition in liquid packaging board. Imbibition roughening was analyzed from 2D shadowgraphs by a dynamic interface recognition algorithm. An idea of investigating flow paths in cardboard samples using potassium iodine in water solution as contrast enhancement substance was introduced. For demonstrating the potential of the tomographic methods, numerical lattice Boltzmann permeability simulations were performed. Experimental measurements were conducted to compare and support the results extracted from tomographic data. A 3D void space segmentation algorithm was utilized to analyze structure of void space in tomographic reconstructions. Tentative results indicate that the new methods can be used to find correlation between pore size heterogeneity and imbibition roughening. Finally, water absorption coefficients of the test samples were calculated utilizing results extracted from the void space segmentation analysis.

    ABSTRACT: Energy is the most common parameter in use to characterize refining action for chemical pulp enhancement and mechanical pulp production. The extent of refining is commonly quantified by specific energy and the severity of the process is quantified by an energy-based intensity. However, energy is not the agent of refining. Forces produce the refining result by imposing strains in fibrous material to break molecular bonds. Energy is a merely a consequence of how forces are applied. This paper discusses the nature of forces in refining, how they can be used to quantify refining action, and how they shed light on the theoretical energy required for the processes.

    ABSTRACT: A new analytical method is introduced that separates the spectral content of paper formation into the contributions of high mass (floc) and lightweight zones. The method enhances the ability to distinguish differences in in-plane distribution of fibrous mass which results from different forming processes, process additives or raw materials. The method is based on a discrete implementation of the one-dimensional continuous wavelet transform applied to data arrays obtained from radiographic or optical transmission images through fibrous webs such as paper. Simulated paper formations were generated to demonstrate the sensitivity of the method to floc size and density. The separate mean energy spectra obtained for flocced and light weight zones of the images were compared. The differences correlated well with the relative skewness observed in the grammage probability distributions for the same samples.

    ABSTRACT: Talc is used traditionally for pitch control in the papermaking industry. The effectiveness of talcs as control agent of dissolved and colloidal pitch is related to their structural and surface characteristics determined by the application of minerals and thermal and surface treatments to obtain different properties, e.g., specific surface, surface energy, surface charge and ratio lipophilic/hydrophilic surface. Five commercial talcs, corresponding to two groups of different mineralogical compositions, have been tested to determine their capacity to adsorb lipophilic contaminants by experiments of adsorption isotherms. The adsorption isotherms of pitch dispersions from Eucalyptus globulus wood on the different talcs were carried out at 50°C. The adsorption took place through a mechanism of colloidal adsorption and the results obtained were fitted to the Langmuir equation. Results show that talc addition to bleached waters or process waters can produce high reductions of colloidal pitch concentrations, at comparatively low doses.

    ABSTRACT: Four mechanical pulps, namely, Spruce TMP, Aspen CTMP, Maple CTMP and Eucalyptus CTMP, were subjected to alkaline peroxide bleaching at various conditions, and their oxalate formation were compared in terms of bleaching conditions, pulp brightness, brightness gain and peroxide consumption. Results show that under similar bleaching conditions, the softwood TMP always produced less oxalate than the three hardwood CTMP pulps. However, the oxalate formation at a given brightness gain depends on the unbleached pulp brightness, and pulps with higher original brightness produced less oxalate for a given brightness target. The difference in the amount of oxalate formed per unit of brightness gain was small between the spruce TMP, maple CTMP and eucalyptus CTMP. For the same pulp the Mg(OH) 2 -based peroxide process produced similar or slightly more oxalate than the NaOH-based process for a given brightness target. Kinetic models were also developed to compare the oxalate formation process and the brightening process.
