Vpliv velikosti iverja in načina segrevanja na hrapavost ivernih plošč : diplomsko delo (visokošolski strokovni študij) = Influence of particle sizes and heating on particle board roughness : graduation thesis (higher professional studies)Luin, Peter, 1982-Raziskovali smo vpliv velikosti iverja na hrapavost površine ivernih plošč. Za izdelavo plošč smo uporabili iverje iz smrekovega lesa; dobili smo ga iz tovarne ivernih plošč Lesna, Otiški vrh. Iverje ... smo presejali v 2 različni frakciji: en del grobe frakcije smo dodatno pomleli, drugega pa termično obdelali in z mokrim pomlevanjem pridobili vlakna. Izdelali smo 3 tipe ivernih plošč in iverno ploščo obdano z vlaknastim slojem ter zanje uporabili različno fino iverje oz. vlakna. Za merjenje hrapavosti površine smo izdelali napravo: ta nam je omogočila daljši zajem profila površine. Ploščam smo tako izmerili hrapavost in gostotne profile po prerezu ter dobljene rezultate primerjali med seboj. Ugotovili smo, da je hrapavost površine ivernih in iverno-vlaknenih plošč odvisna od prostorninske mase površinskega sloja. Večja kot je prostorninska masa površinskega sloja, manjša je hrapavost površine plošč; hrapavost površine na spodnji strani plošč pa manjša kot na zgornji. Razlika v hrapavosti nastane zaradi usipanja iveri proti dnu med natresanjem in prenosom pogače do stiskalnice: spodnja stran plošče tako vsebuje večjo količino finejšega iverja.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [P.
