Drying characteristics of wood of invasive tree species growing in an urban environment = Določanje sušilnih karakteristik lesa invazivnih drevesnih vrst rastočih v urbanem okoljuPlavčak, Denis ...V vrtovih in parkih se zaradi oblik in privlačnega videza vse pogosteje razširjajo neavtohtone drevesne vrste, ki so podrejene posebnim gojitvenim in obrezovalnim ukrepom. Pogosto lahko postane ... njihova širitev nekontrolirana, celo invazivna. V primeru takih dreves je struktura lesa bolj heterogena, les je bolj verjetno otiljen, diskoloriran in okužen ter ima višjo vlažnost. Sušenje takšnega lesa je težavnejše in ne omogoča uporabe standardnih sušilnih programov. Raziskali smo kinetiko sušenja treh lesnih vrst (robinije - Robinia pseudoacacia; amerikanskega javorja - Acer negundo in divjega kostanja - Aesculus hippocastanum). Sušili smo deske debelin 22 mm, 28 mm in 46 mm pri 20 °C in 40 °C. Ob tem smo spremljali kakovost sušenja. Ocenjevali smo vlažnostni gradient, sušilne napetosti in pojav značilnih napak pri sušenju.Pri sušilnih preizkušancih so bili vlažnostni gradienti pri vseh lesnih vrstah razmeroma nizki, zato nismo zabeležili visokih sušilnih napetosti. Raziskave so pokazale, da je zaradi ugotovljene nevarnosti kolapsa potrebno previdno sušenje lesa svežega javorja, da se prepreči krivljenje desk, zlasti ob prisotnosti številnih grč in večjem odstopanju poteka lesnih vlaken. Polovični časi sušenja so nakazovali daljše sušenje debelejših preizkušancev robinije in zelo previdno sušenje javorja. Potrdili smo uporabnost kinetike polovičnega časa sušenja različnih vrst in debelin lesa.Source: Les = Wood. - ISSN 0024-1067 (Letn. 68, št. 2, dec. 2019, str. 31-43)Type of material - article, component part ; adult, seriousPublish date - 2019Language - englishCOBISS.SI-ID - 3168393
