dc.description.abstractThe aim of this study was to investigate the use of birch wood, one of the most important wood spe-cies used in the plywood industry, especially in Europe, the Nordic countries, Poland, Belarus and Russia as an al-ternative to beech wood. For this purpose, comparison was made of their economic and technological properties. In fi ve-ply plywood manufacturing, beech (Fagus orientalis Lipsky) and birch (Betula pendula) veneer sheets were used with melamine urea formaldehyde (MUF) and urea formaldehiyde (UF) resins. Some mechanical properties such as shear strength, bending strength and modulus of elasticity of plywood panels were conducted according to EN 314-1 and EN 310, respectively. Mean mechanical strength obtained for birch plywood panels was quite above the limit values specifi ed in the related standards. When taking into consideration the annual increment of beech and birch trees in 1 ha and the time they need to reach suitable diameters for the manufacturing of rotary cut veneers, it was calculated that birch trees provide 2.46 times more physical harvesting than beech trees.
dc.description.abstractU radu je istra?ivana uporaba brezovine kao jedne od najva?nijih vrsta drva koja se upotrebljava kao alternativa bukovini za proizvodnju furnirskih plo?a, posebice u Europi, u nordijskim zemljama, Poljskoj, Bjelo-rusiji i Rusiji. Za potrebe rada uspore?ivana su njihova ekonomska i tehnološka svojstva. U proizvodnji furnirske plo?e od pet slojeva upotrijebljeni su listovi furnira od bukovine (Fagus orientalis Lipsky) i brezovine (Betula pendula), koji su slijepljeni ljepilom na bazi melamin-urea-formaldehidnih (MUF) i urea-formaldehidnih (UF) smola. Ispitana su mehani?ka svojstva furnirskih plo?a prema normi EN 314-1 i EN 310, i to ?vrsto?a na smicanje, ?vrsto?a na savijanje i modul elasti?nosti. Dobivene srednje vrijednosti ?vrsto?e brezovih i bukovih furnirskih plo?a bile su znatno iznad grani?nih vrijednosti navedenih u normama. Kada se u obzir uzme godišnji prirast bukve i breze na 1 ha šume i vrijeme potrebno za postizanje odgovaraju?ih promjera za proizvodnju ljuštenih furnira, izra?unano je da breza osigurava 2,46 puta više raspolo?ive koli?ine za sje?u od bukve.
