Sprememba upogibne trdnosti in modula elastičnosti iverne in OSB plošče zaradi izpostavitve vodi : diplomsko delo = Change in bending strength and modulus of elasticity of particleboard and OSB due exposure to water : B. Sc. thesis

Černe, Luka

V nalogi smo ugotavljali vpliv vode na debelinski nabrek, upogibno trdnost in modul elastičnosti iverne in OSB plošče. Plošče smo za 24 oz. 240 ur potopili v vodo. Eno serijo preskušancev smo po 240 ... urnem namakanju v sušilniku pri 103 °C posušili do absolutno suhega stanja. Ugotovili smo, da se z daljšanjem časa izpostavitve debelinski nabrek plošč veča. Večji nabrek smo opazili pri OSB plošči. Pri sušenju sta se obe plošči procentualno približno enako skrčili. Modul elastičnosti je bil v začetnem suhem stanju pri obeh ploščah približno enak, upogibna trdnost pa je bila višja pri OSB plošči. Po 24 urah namakanja v vodi smo pri obeh ploščah ugotovili približno enak padec trdnosti in modula elastičnosti. Posledica 240 urnega namakanja je bilo dodatno poslabšanje mehanskih lastnosti, ki je bilo bistveno večje pri OSB plošči. Mehanske lastnosti predhodno namočenih plošč so se s sušenjem izboljšale, višje vrednosti smo izmerili pri iverni plošči.
