20.500.12556/RUL-132226 Impregnability of Paulownia and Populus wood with copper based preservatives Učinci impregnacije drva paulovnije i topole zaštitnim sredstvima na bazi bakra The importance of fast growing wood species such as Paulownia and Populus wood is increasing. Unfortunately, these wood species do not have durable wood, so they have to be protected for use in outdoor applications. One of the most important groups of wood preservatives for heavy duty applications is the copper based one. Paulownia and Populus wood samples were thus treated with copper-ethanolamine (Cu/MEA) and acid copper chromate (ACC) according to various treatment processes: Bethell, Rüping and dipping. The dipping treatment was performed with various submersion times, ranging from 1 min to 10 days. The uptake of preservative solution, penetration and colour of the specimens were then determined. The results clearly indicate that the permeability of Paulownia is not as good as that of Populus wood. The permeability of Paulownia can be improved with the proper selection of impregnation procedure and wood preservatives. Cu/MEA was found to be more suitable for treatment of Paulownia wood than classical ACC. impregnation dipping Paulownia Populus penteration uptake of preservative solution impregnacija potapljanje pavlovnija topol penetracija navzem true false true Angleški jezik Hrvaški jezik Neznano 2021-10-18 13:00:23 2021-10-18 13:00:26 2022-09-12 04:11:31 0000-00-00 00:00:00 2017 0 0 Str. 211-218 no. 3 Vol. 68 2017 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*841.3 0012-6772 10.5552/drind.2017.170 2816393 RAZ_Rasouli_Davood_2017.pdf RAZ_Rasouli_Davood_2017.pdf 1 5747F33BAB1E9D2FC475DC73164CEE93 1da0d7cf47fc6e713511a4fcbe86ffad0598bae0221240f82ab3a067f85e4821 2a335bae-3004-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=149779 Biotehniška fakulteta 0 0 0
