Vpliv toplotne obdelave lesa na njegove sorpcijske značilnosti : diplomsko delo (visokošolski strokovni študij) = Influence of thermal treatment of wood on its sorption characteristics : graduation thesis (higher professional studies)Vrečko, Jože, 1978-Les je po svoji naravi higroskopen in se vedno skuša prilagoditi spreminjajočim se klimatskim razmeram. Pri postopkih predelave in obdelave, predvsem pri povišanih temperaturah, se higroskopske ... lastnosti lesa spreminjajo. Na vlažnih (Uz1 = 17 %) in suhih (Uz2 = 7 %) vzorcih smo proučevali vpliv termične obdelave pri 3 temperaturah (T1 = 20 °C, T2 = 100 °C in T3 = 180 °C) in 2 trajanjema pregrevanja (t1 = 5 min in t2 = 10 min) na sorpcijske značilnosti, ki se odražajo v doseganju ravnovesnih vlažnosti v postopkih desorpcije in adsorpcije na 6 stopnjah relativne zračne vlažnosti (j= 15 %, j = 32 %, j = 40 %, j = 61 %, j = 75 %, j = 84 %) pri temperaturi zraka 39 °C +- 1,5. Kot statistično značilni dejavniki na celem higroskopskem območju so se izkazali: razlike med adsorpcijo in desorpcijo, temperatura, in pri visokih vlažnostih tudi čas toplotne obdelave. Začetna vlažnost vzorcev ni statistično značilno vplivala na sorpcijske lastnosti. Za izris sorpcijskih krivulj smo eksperimentalnim podatkom prilagodili Dentov matematični model. Sorpcijske značilnosti smo primerjali z ravnovesnimi stanji pri temperaturi 20°C +- 1,5.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [J.
