Uporaba utekočinjenega odsluženega lesa za ponovno zaščito lesa : diplomsko delo - univerzitetni študij = Use of liquefied recovered wood for wood preservation : graduation thesis - university studies
Fridrih, Dejan
Bakrove in borove pripravke pogosto uporabljamo za zaščito lesa, saj delujejo kot zanesljivi fungicidi. Določili smo optimalne pogoje utekočinjenja s CCB zaščitenega lesa. CCB je okrajšava za ...biocidni proizvod za les, ki vsebuje bakrove (Cu), kromove (Cr) in borove (B) spojine. Ugotovili smo, da ostanki Cu, Cr in B v impregniranem lesu pri procesu utekočinjenja niso imeli bistvene vloge. Zanimale so nas fungicidne lastnosti utekočinjenega s CCB impregniranega lesa in utekočinjenega nezaščitenega lesa. Utekočinjen nezaščiten les je deloval bolj fungicidno, kot utekočinjen, s CCB impregniran les, saj je zavrl rast določenih gliv. Utekočinjen, s CCB impregniran les je v nekaterih primerih deloval celo spodbujevalno na rast gliv. Ko smo primerjali rezultate vpliva etilenglikola in žveplove(VI) kisline na delovanje gliv, smo ugotovili, da je ta vpliv primerljiv z delovanjem utekočinjenega lesa najvišje koncentracije. Iz tega sklepamo, da fungicidne lastnosti utekočinjenega lesa določata etilenglikol in žveplova(VI) kislina in ne neposredno utekočinjen les.
