20.500.12556/RUL-548 Lastnosti lesa bršljana diplomsko delo - univerzitetni študij Raziskali smo tiste izbrane lastnosti lesa navadnega bršljana (Hedera helix L.), ki bi utegnile predvideti njegovo uporabo. Raziskali smo anatomsko zgradbo in makroskopske posebnosti, vlažnost v svežem stanju, gostoto, anizotropijo krčenja in nabrekanja, kazalnike dimenzijske stabilnosti ter tlačno in upogibno trdnost bršljanovega lesa. Raziskava je pokazala, da bršljanov les spada med polvenčasto porozne drevesne vrste. Gostota absolutno suhega lesa je 522 kg/m3. Vlažnost svežega lesa, ki jo zasledimo, znaša povprečno 92 %. Anizotropija krčenja in nabrekanja je zelo variirala, vendar lahko povzamemo, da so skrčki in nabreki primerljivi z lesovi z nižjo gostoto. Kazalniki dimenzijske stabilnosti so ugodni ali normalni, razen sorpcijskega kvocienta in vrednosti anizotropije, ki sta neugodna. Mehanske lastnosti lahko primerjamo z lipo, topolom in smreko. Bršljanov les je primeren za galanterijske izdelke. We investigated those selected properties of plain wood ivy (Hedera helix L.),which could anticipate for its use. We studied the anatomical structure and macroscopic specialities, humidity in fresh state, density, shrinkage and swelling anisotropy, indicators of dimensional stability and compressive and flexural strength of ivy wood. The research showed that ivy wood is semi-ring-porous tree species. Absolutely dry wood density is 522 kg/m3. Average humidity of fresh wood is 92 %. Anisotropy of shrinkage and swelling is very varied, but the constrictions and swelling can be compared to woods with lower density. Dimensional stability indicators are favourable or normal, with the exception of sorption quotient and anisotropy, which are unfavourable. Mechanical properties can be compared with linden, poplar and spruce woods. Ivy wood is suitable for haberdashery products. navadni bršljan Hedera helix L. mehanske lastnosti vlažnost sorpcija gostota ivy Hedera helix L. mechanical properties humidity sorption density true false false [K.
