20.500.12556/RUL-158775 Identifikacija lesa izbranih tropskih vrst za talne obloge diplomsko delo - univerzitetni študij Identification of selected tropical wood species for flooring graduation thesis - university studies Na trgu za talne obloge ponujajo različne tropske lesne vrste, njihova komercialna imena pa niso vedno pravilna. Pri trgovcih talnih oblog smo pridobili devetindvajset vzorcev talnih oblog iz tropskih lesnih vrst. Iz vzorcev smo izdelali preparate za mikroskopsko identifikacijo. Identifikacija je razkrila, da se pet vrst od devetindvajsetih prodaja pod napačnim imenom. Raziskanim vrstam smo poiskali podatke o fizikalnih, mehanskih in obdelovalnih lastnostih lesa in jih na podlagi zbranih podatkov razvrstili v štiri skupine po primernosti za talne obloge. Najprimernejše vrste za izdelavo talnih oblog so: Dipteryx odorata, Manilkara bidentata, Bowdichia spp. in Guibouritia spp. To so vrste, ki imajo visoko gostoto in trdoto lesa, ugodno anizotropijo krčenja, so odporne proti biološkim škodljivcem in so uvrščene razred ogroženosti 3 ali 4. Od raziskanih vrst je za talne obloge neprimerna Acacia mangium, ki ima nizko gostoto ter trdoto in neugodno anizotropijo krčenja. Poleg omenjenih lastnosti pa je pri izbiri lesa za talne obloge pomemben tudi estetski videz in cena lesa. There are various tropical timber species on the market of wood for flooring, however their commercial names are not always correct. We got twenty-nine samples of tropical timber species from the floor traders. Out of those samples we have made slides for microscopic wood identification. The identification showed, that out of twenty-nine species, five are sold under the incorrect name. All the examined species were given data about physical and mechanical and machinability properties and were later classified into four groups, based on the suitability for floor coverings. The most appropriate ones are: Dipteryx odorata, Manilkara bidentata, Bowdichia spp. in Guibouritia spp. Those are also the species that contain wood with a high density and hardness, a favorable shrinkage anisotropy, have durable woodand use class 3 or 4. The least appropriate species is Acacia mangium, which has an unfavourable shrinkage anisotropy and low density and hardness. Next to all above mentioned properties, aesthetic appearance and the price, are also important when choosing wood for flooring. les talne obloge tropske vrste identifikacija mikroskopija Intsia Astronium Bowdichia Acacia Manilkara Milicia Eucalyptus Afzelia wood flooring tropical species identification microscopy Intsia Astronium Bowdichia Acacia Manilkara Milicia Eucalyptus Afzelia true false false Ž.
