Mehanske in biološke lastnosti iverne plošče narejene iz odsluženega zaščitenega lesa : diplomsko delo : univerzitetni študij = Mechanical and biological properties of particleboards made of impregnated wood removed from the service : graduation thesis : university studiesKrpan, AnjaKoličina odsluženega zaščitenega lesa je vsak dan večja, v prihodnosti pa bo se naraščala. Takšnega lesa ne smemo kar prosto odlagati ali sežigati. Tudi shranjevanje odsluženega lesa na posebnih ... deponijah je samo začasna rešitev. Ta material bo treba na nek način odstraniti ali pa vsaj zmanjšati njegovo toksičnost. Zato se raziskave osredotočajo na ponovno uporabo odsluženega zaščitenega lesa. Želeli smo ugotoviti, kakšne lastnosti bo imela iverna plošča, narejena iz odsluženega lesa. Uporabili smo iveri iz odpadnega električnega droga, ki je bil pred 50 leti zaščiten s CCA pripravkom. Del teh iveri smo očistili, tako da smo jih izprali z vodovodno vodo. Lastnosti izpranih iveri smo primerjali z neizpranimi, iverjem čiste jelke, industrijskim iverjem in bioremediiranim iverjem. Iz vseh tipov iveri smo izdelali vzorčne enoslojne iverne plošče. Naredili smo preizkus zlepljenosti iveri, sejalno analizo, kemijsko analizo z infrardečo spektroskopijo ter izračunali izgubo mase vzorcev po izpostavitvi glivam. Ugotovili smo, da bi bile mehanske lastnosti te plošče slabše, biološke pa zadovoljive. Neizprane iveri bi lahko uporabili za izdelavo srednjega sloja pri troslojni iverni plošči. Vendar le v manjši količini, od 10 % do 20 % deležu, katerega bi dodajali k industrijskemu iverju. Te iveri še vedno vsebujejo določeno vrednost biocidov, zato bi bile te iverne plošče primerne le za zunanjo uporabo.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [A.
