20.500.12556/RUL-648 Vpliv poteka stiskanja na gostotni profil iverne plošče diplomsko delo - univerzitetni študij Pressing process impact on the vertical density profile of the particle board graduation thesis - university studies Ugotavljali smo v kolikšni meri sam potek stiskanja vpliva na gostotni profil iverne plošče in njene mehanske lastnosti. V laboratorijskih pogojih smo izdelali 6 plošč, kjer smo spreminjali potek tlaka stiskanja. Gostotni profil smo izmerili s pomočjo naprave za merjenje vertikalne porazdelitve prostorninskih mas. Poleg gostotnega profila plošče smo ugotavljali še upogibno in razslojno trdnost. Ugotovili smo, da z nižjim tlakom stiskanja dobimo večjo gostoto iverne plošče pri čemer je potrebno poudariti, da gre za stiskanje z uporabo distančne letve; da obstaja korelacija med gostoto sredice in razslojno trdnostjo, ter da na upogibno trdnost ne vpliva samo gostota zunanjega sloja iverne plošče ampak delno tudi gostota sredice plošče. We assessed the extent to which the pressing process affects the density profile of the particle board, and its mechanical properties. 6 particle boards were produced, quite equal as regard their structure; just the pressing process was variable. Density profile was measured using an apparatus to measure the vertical distribution of volume by mass. In addition to the density profile, the bending properties and internal bond of the panels were tested. We found out that a lower pressure of compression gives a high density particle board; that there exist a correlation between central density and internal bond; and that the bending strength not only affects the surface density but also a central density of the particle board. iverna plošča gostotni profil diagram stiskanja upogibna trdnost razslojna trdnost particle board density profile pressing diagram bending properties internal bond true false false [M.
