Fungicidne lastnosti termično modificirane slame : diplomski projekt = Fungicidal properties of thermally modified straw : B. Sc. thesis

Mesarič, Marko, 1993-

Slama je naravni material, ki nastaja kot stranski produkt v kmetijstvu pri pridelavi žit. V preteklosti so jo pogosto uporabljali v gradbeništvu, predvsem za strešno kritino, za izdelavo ometov ali ... kot izolacijski material. Tako kot tradicionalni način gradnje pridobiva na pomenu tudi slama. Na lignocelulozne materiale vplivajo biotski in abiotski dejavniki razkroja. V zadnjem času poročajo o znatnem skrajšanju življenjske dobe slamnatih streh, zato iščemo rešitve za njihovo zaščito. Ena od možnih zaščit je tudi termična modifikacija, kar je predmet raziskave. Slamo smo tako termično modificirali po postopku začetnega vakuuma pri temperaturah med 170 °C in 210 °C. Iz modificirane slame smo nato pripravili manjše snopiče in jih izpostavili trem različnim lesnim glivam po modificiranem standardu SIST EN 113. Vzporedno smo določili tudi sorpcijske lastnosti modificirane slame. Ugotovili smo, da ima termična modifikacija podoben vpliv na slamo kot na les. Višja kot je bila namreč temperatura, manj intenziven je bil razkroj gliv. Podoben vpliv je opaziti pri sorpcijskih lastnostih. Vzorci, modificirani pri višjih temperaturah, so se pri istih klimatskih pogojih manj navlažili kot kontrolni vzorci. Z višanjem temperature modifikacije pa so se slami poslabšale mehanske lastnosti in slama je postajala vedno bolj krhka.
