Properties of one-layer experimental particleboards from willow (Salix viminalis) and industrial wood particles

Abstract

The objective of this study was to investigate some mechanical and physical properties of one-layer particleboards made from various willow (Salix viminalis) and industrial pine wood particle mixtures bonded with urea formaldehyde resin. Modulus of elasticity and modulus of rupture decreased, whereas internal bond and screw holding strengths increased with increasing willow particle content. The decrease in bending properties was rather small; these properties of particleboards containing 50 % willow particles were on average smaller by about 10 % than particleboards containing only industrial wood particles. Increasing the willow particle content resulted in improved water absorption and thickness swelling. The willow Salix viminalis can be considered as a substitute for pine wood for manufacturing of particleboards. Eigenschaften einschichtiger Versuchsspanplatten aus Weidenspänen (Salix viminalis) und industriellen Holzspänen Zusammenfassung Ziel dieser Studie war es, einige mechanische und physikalische Eigenschaften einschichtiger Spanplatten zu untersuchen, die aus verschiedenen Mischungen von Weidenspänen (Salix viminalis) und industriellen Kiefernholzspänen hergestellt und mit Harnstoffharz verklebt wurden. Der Elastizitätsmodul und die Biegefestigkeit nahmen mit zunehmendem Anteil an Weidenspänen ab, wohingegen die Querzugfestigkeit und der Schraubenausziehwiderstand zunahmen. Die Abnahme der Biegeeigenschaften war relativ gering; bei Spanplatten mit 50 % Weidenspäneanteil waren diese Eigenschaften um durchschnittlich 10 % geringer als bei Spanplatten aus ausschließlich industriellen Holzspänen. Eine Erhöhung des Weidenspäneanteils führte zu einer geringeren Wasseraufnahme und Dickenquellung. Salix viminalis kann als Ersatz für Kiefernholz zur Herstellung von Spanplatten in Betracht gezogen werden.

Utilization of Kattha (Acacia catechu) extracted wood chips in combination with PF (Phenol-Formaldehyde) resin as a binder to produce a medium-density particle board

“…The level of dispersion around the mean was 3.98 per cent, as indicated by the value of the coefficient of variation. The current findings were consistent with those of Warmbier et al (2013) [22] , who investigated the impact of density and resin content on the mechanical characteristics of particleboards with a willow (Salix viminalis) core layer. Particle boards' internal bond (IB), modulus of elasticity (MOE), and modulus of rupture (MOR) were studied.…”

Resin Content and Board Density Dependent Mechanical Properties of One-Layer Particleboard Made from Willow (Salix viminalis)

“…They are cultivated in Poland for energy purposes, and their suitability for particleboard industry was confi rmed by a number of studies (Frąckowiak, 2007;Frąckowiak et al, 2008;Warmbier et al, 2013Warmbier et al, , 2014aWarmbier et al, , 2014b). Sean and Labrecque (2006) found the usefulness of Quebec clones of this willow.…”

Effect of Ash from Salix viminalis on the Biomass and Heating Value of Zea mays and on the Biochemical and Physicochemical Properties of Soils

“…These stress conditions may be induced by excessive soil fertilization with wood ash obtained from, e.g., osier (Salix viminalis). S. viminalis is a fast-growing species with few soil requirements [7]. It may be cultivated in areas of low agricultural productivity and wastelands [5].…”
