Razbarvanje utekočinjenega lesa z vodikovim peroksidom : diplomsko delo - visokošolski strokovni študij = Discolouration of liquefied wood with hydrogen peroxide : graduation thesis - higher professional studies

Centa, Matjaž

S termokemično reakcijo z glicerolom in s katalizatorjem žveplovo(VI) kislino smo utekočinili topolov les. Določili smo izkoristek utekočinjenja, nato pa izvedli poskuse razbarvanja utekočinjenih ... zmesi z vodno raztopino vodikovega peroksida. Preučili smo tudi morebitni vpliv vrednosti pH na razbarvanje utekočinjenega lesa. Produkte reakcije utekočinjenega lesa z raztopinami vodikovega peroksida smo nanesli na steklene ploščice in filme utrdili pri temperaturi 130 °C. V nadaljevanju smo izmerili naslednje lastnosti utrjenih filmov: stopnja utrditve, debelina filma, odpornost proti tekočinam, prožnost po Petersu, trdota po Königu in barva. Ugotovili smo, da je bilo razbarvanje utekočinjenih zmesi z vodnimi raztopinami vodikovega peroksida minimalno. Opazili smo tudi, da so bili premazi iz utekočinjenega lesa higroskopni.
