Effects of manufacturing parameters on mechanical properties of particleboards with the core layer made from willow Salix viminalis. Three-layer experimental particleboards were prepared using the willow Salix viminalis particles for the core layer and industrial pine particles for the face layers. The press temperature (180 and 200°C), press time (4 and 6 min) and shelling ratio (0.3 and 0.4) were variable parameters. The modulus of elasticity (МОЕ), modulus of rupture (MOR), internal bond (IB) and screw holding strength (SHS) of particleboards were investigated. In general, the considered factors significantly affected the mechanical properties of particleboards.

Wpływ wybranych parametrów wytwarzania na właściwości mechaniczne płyt wiórowych z warstwą wewnętrzną z wierzby Salix viminalis. Wykonano trzywarstwowe płyty wiórowe stosując wióry wierzby Salix viminalis na warstwę wewnętrzną i przemysłowe wióry sosnowe na warstwy zewnętrzne. Parametrami zmiennymi były: temperatura prasowania (180 i 200°C), czas prasowania (4 i 6 min) i stosunek grubości warstw zewnętrznych do grubości płyty (0.3 i 0.4). Badano moduł sprężystości (MOE), wytrzymałość na zginanie (MOR), wytrzymałość na rozciąganie poprzeczne (IB) i zdolność utrzymania wkręta (SHS). Uwzględnione parametry na ogół oddziaływały istotnie na badane właściwości mechaniczne.
