Effects of different ammonium lignosulfonate contents on the crystallization, rheological behaviors, and thermal and mechanical properties of ethylene propylene diene monomer/polypropylene/ammonium lignosulfonate composites, TAPPI Journal January 2020

ABSTRACT: Thermoplastic elastomer (TPE), made from ethylene propylene diene monomer (EPDM) and polypropylene (PP) based on reactive blending, has an excellent processing performance and characteristics and a wide range of applications. However, there are currently no reports in the literature regarding the usage of TPE in making composite boards. In this paper, EPDM, PP, and ammonium lignosulfonate (AL) were used as the raw materials, polyethylene wax was used as the plasticizer, and a dicumyl peroxide vulcanization system with dynamic vulcanization was used to make a new kind of composite material. This research studied the influences of the AL contents on the crystallization behaviors, rheological properties, thermal properties, and mechanical properties of the composites. The results showed that the AL content had a noticeable impact on the performance of the composite board. Accordingly, this kind of composite material can be used as an elastomer material for the core layer of laminated flooring.

Effects of variability of wood chip composition on recovery cycle operation, TAPPI Journal January 2026

ABSTRACT: Fluctuations in wood chip properties in kraft pulp mills, which often follow seasonal patterns, can lead to changes or disruptions in the operation of the recovery cycle whereby the root causes are not immediately obvious. In some cases, these changes are attributed to operational adjustments in the digester or brownstock washing areas resulting from the variability in wood characteristics. Varying wood chip characteristics that have the most significant impact on the recovery cycle operation include the content of non-process elements (NPEs), extractives, and properties influenced by chip storage conditions. Elevated levels of NPEs, often associated with a higher influx of wood bark into the digester, can negatively affect the entire recovery cycle. Increased levels of chlorine and potassium can lead to severe fouling and corrosion in the recovery boiler. Higher concentrations of silicon, aluminum, phosphorus, magnesium and calcium in the chips may accelerate scaling in the evaporation plant, impair dregs and lime mud settling and filtering, reduce lime mud solids content and lime availability, and increase the amounts of dregs, grits, and purged lime mud. This technical review provides an overview of the most significant effects that changes in wood chip quality can potentially exert on various processes within the kraft recovery cycle.

Estimating dose and interaction of X-rays with cellulose-based fibrous materials using micro-computed tomography, TAPPI Journal March 2026

ABSTRACT: Micro-computed tomography (ìCT) has a reputation as a nondestructive analysis method. Unfortunately, this leads to the common misconception that radiation damage of the sample does not play a role. With the increased use of ìCT in laboratory-based machines, more and more cellulose-based materials are studied. In this paper, we show with three examples that radiation damage is important in dry and wet paper and in viscose fibers. In an attempt to quantify radiation damage, we came up with a workflow that enables researchers to predict the X-ray dose within a laboratory-based ìCT machine. This gives researchers the possibility to quantitatively judge the influence of radiation damage on each measured sample. While one cannot extend the measured doses from one machine to another, one can still apply the work flow presented in this study to any ìCT setup. In this way, it is possible to minimize radiation damage by choosing the best parameters in a ìCT for obtaining perfect data with no or little radiation damage.
