Vpliv parametrov obdelave z DBP plazmo s plavajočo elektrodo na omočljivost lesa : diplomsko delo = Influence of Fe-DBP plasma treatment on the wettability of wood : B. Sc. thesisTodorović, Dejan, 1995-V diplomskem delu smo analizirali površino bukovega (Fagus sylvatica L.) in smrekovega (Picea abies (L.) Karst.) lesa, po obdelavi z dielektrično barierno razelektritveno (DBD) plazmo s plavajočo ... elektrodo. Znano je, da na učinek obdelave površin lesa s plazmo vplivajo zunanji (lastnosti materiala in plina, dimenzije elektrod in reaktorja, električna moč, čas tretiranja itd.) in notranji (lastnosti plazme) dejavniki. Pojav plazme smo posneli s fotokamero in analizirali z računalniškim programom. Z določanjem stičnih kotov vode na obdelanih in neobdelanih površinah lesa smo preučili vpliv spreminjanja zunanjih parametrov naprave na omočljivost lesa. Zunanji parametri, ki smo jih spreminjali, so bili podajalna hitrost, razdalja med dielektrikoma (RME) in oddaljenost površine lesa od dielektrikov (RMES). Z vrstičnim elektronskim mikroskopom smo opazovali strukturo in topografijo površin vzorcev. Izmerjene sive vrednosti analiziranih razelektritev pri obdelavi lesa bukve so bile višje kot pri obdelavi lesa smreke. Rezultati so pokazali, da se stični kot kapljic vode zmanjša z zniževanjem podajalne hitrosti. Površino smrekovega lesa voda bolje omaka pri RMES 0,5 mm, pri bukovini pa pri 1 mm. Optimalna razdalja pri smrekovem vzorcu med elektrodama je 8 mm, pri bukovem pa so najboljši rezultati pri 10 mm.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [D.
