Vpliv transpiracijskega sušenja na spremembe barve bukovine med komorskim sušenjem : diplomsko delo - visokošolski strokovni študij = Influence of transpiration on discolouration of beech wood during kiln drying : graduation thesis - higher professional studiesŠifrar, UrošRaziskovali smo učinek sečnje na suš in transpiracijskega sušenja na obarvanje bukovine (Fagus sylvatica L.) med postopkom konvekcijskega sušenja. Med 4 postopki sušenja (pri temperaturah 20 °C in 38 ... °C ter relativnih zračnih vlažnostih 33 % in 75 %) smo s sistemom CIE L a b spremljali spremembo barve po prerezu 25 mm in 50 mm debelih elementov. Primerjali smo obarvanje med takoj po poseku drevesa tehnično sušenimi elementi in tistimi, ki smo jih tehnično sušili po 16 dnevnem transpiracijskem sušenju. Les po sečnji na suš je imel nižjo in predvsem bolj enakomerno razporejeno vlažnost. Vpliva transpiracijskega sušenja na kinetiko sušenja nismo ugotovili, značilen pa je bil ugoden vpliv na obarvanje. Celotna barvna razlika in razlika svetlosti sta bili pri transpiracijsko sušenem lesu značilno manjši pri vseh postopkih tehničnega sušenja. Manjše tveganje obarvanja transpiracijsko sušenega lesa ostaja tudi, če poteka proces pri višji temperaturi in manjši ostrini.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [U.
