Skliar, Dariia Selected physical and mechanical properties of plywood faced with wood slices / Dariia Skliar, Mária Šmidriaková, Ján Sedliačik. -- obr., tab. -- Lit. - The forest based sector, even at the stage of logging, loses approximately 15 % of wood raw material in the form of branches, bark, tree tips, etc. The general utilisation of waste branches is combustion, production of biofuel or building skidding roads. The paper describes a method of using of one type of cutting waste – tree branches – as a decorative material for facing of wood-based panels. Three-layer and five-layer birch plywood was faced on both sides by walnut (Juglans regia), birch (Betula pendula), or linden (Tilia europaea) wood slices. The environmentally safe PVAC adhesive was used to impregnate the slices and join the veneers. The panels were tested for modulus of elasticity in bending and bending strength in accordance with the standards EN 310 and EN 325 and calculated according to EN 326-1. The facing was tested for surface soundness using the pull-off test according to the standard EN 311. The best results were obtained for the plywood faced with birch slices. The birch faced three-layer birch plywood can be classified as F 30 E 30. The birch faced five-layer plywood can be classified higher – F 40 E 40. Based on the results of surface soundness has also been found out that wood slices, impregnated with glue before pressing, resist stress better than non-impregnated slices.
