Vpliv ekstraktivov lesa in skorje robinije (Robinia pseudoacacia L.) na hidrofobnost in mehanske lastnosti ivernih plošč : diplomsko delo = Effect of wood and bark extracts of black locust (Robinia pseudoacacia L.) on the hydrophobicity and mechanical properties of particle boards : B. Sc. thesisKovič, Bor JanezCilj eksperimenta je ugotoviti optimalni postopek ekstrakcije hidrofobnih ekstraktivov iz lesa robinije (Robinia pseudoacacia) ter vpliv impregnacije iveri z ekstraktom robinije na relevantne ... lastnosti enoslojne iverne plošče. Ekstrakcijo smo izvedli z destilirano vodo, 50 % vodno raztopino acetona in 50 % vodno raztopino etanola. Največ ekstraktivov, fenolov in flavonoidov smo iz lesa robinije pridobili z 50 % acetonom (aq). Z dobljenim ekstraktom smo impregnirali iveri smreke, katere smo nato uporabili za izdelavo 8 mm debele enoslojne iverne plošče. Najmanjši debelinski nabrek smo ugotovili pri ploščah impregniranih z acetonskim ekstraktom. Ekstrakcijo acetona smo ponovili z uporabo različno velikih gradnikov robinije in sicer velikostni razred 1, 2 in 4. Raziskava je pokazala, da impregnacija iveri z ekstraktom robinije zmanjša debelinski nabrek in emisijo formaldehidaType of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [B.
