20.500.12556/RUL-206 Vpliv velikosti iverja in delež dodanega lepila na stopnjo oblepljenosti diplomsko delo (visokošolski strokovni študij) Influence of the particle sizes and adhesive quantity on surface covered with adhesive graduation thesis (higher professional studies) Proučevali smo, v kolikšni meri vplivata tako delež dodatnega lepila (faktor oblepljanja) kot tudi velikost frakcije iverja na dejansko stopnjo oblepljenosti ivernih delcev. S pomočjo slikovne analize smo prikazali, pri katerih velikostih frakcije in pri kateri stopnji oblepljanja je delež lepila največji. Za lažjo analizo smo lepilu dodali barvilo, ki je pod vplivom fluoroscentne svetlobe oblepljeno površino obarvalo rdeče. Z digitalnim fotoaparatom smo preko mikroskopa poslikali vzorce in jih obdelali s programom za analizo slike, ki je omogočal izmero površine celotnega in površino oblepljenega iverja. Izračunali smo stopnjo oblepljenosti iverja pri različnih stopnjah oblepljanja. Ugotovili smo, da je ob višjem faktorju oblepljanja in večji frakciji večja dejanska oblepljenost iverja. S pomočjo slikovne analize smo opazovali tudi nanos lepila na iverne delce in ugotovili, da pri delcih z manjšo površino pride do prekritja z lepilom, medtem ko se pri večjih frakcijah lepilo nanese točkovno. It was researched how the blending factor and the size of particles influence the blending level. Using the image analysis it was described which particle sizes and which blending degree contain more glue. To distinct better the blended - red colored from non blended areas of particles a special pigment was added to the gluue; then the samples were placed under the fluoroscent light. To define areas of the whole parts and those of the blended ones the images, obtained by a digital camera and a microscope, were processed using computer programme for picture analysis. The level of the blended particles was calculated at different blending levels. It was found out that at higher blending levels and larger size particles the blending is higher. Usage of the image analysis helped us to observe how the glue was spread upon the particles; smaller were practically poured all over, while bigger particles had glue spread in spots. iverje sejalna analiza oblepljanje iverja slikovna analiza particle sowing analysis bonding image analysis true false false [J.
