20.500.12556/RUL-138587 Proučevanje penetracije lužila v les Assessment of the stain penetration in wood Po postopku luženja z vodnim lužilom so v lesnoobdelovalnem podjetju naleteli na problem različnega nabreka posameznih letvic znotraj lepljenega elementa. Zaradi tega smo obstoječe lužilo poskušali modificirati na ta način, da bi zmanjšali njegovo penetracijo v les. Pripravili smo 15 novih formulacij, še pred tem pa smo morali razviti hitro, enostavno in zanesljivo metodo za določanje globine penetracije lužila v les. Ugotovili smo, da so štirje novi pripravki penetrirali signifikantno manj od izvornega vodnega lužila. Le-te bomo preskusili tudi v industrijskem merilu. Dobljene razlike v globini penetracije preskušenih pripravkov so izkazale, da je novo razvita metoda zanesljiva. Kljub temu pa jo bomo v naših nadaljnjih raziskavah poskušali izboljšati. Prav tako bomo proučili vpliv vlažnosti lesa pred luženjem na globino penetracije lužila. During the staining a company, producing wood furniture, encountered a problemof uneven swelling of small boards in glued elements. Therefore we tried to modify the used stain in the way that it would penetrate less into wood. We prepared 15 modified formulations of the waterborne stain, but firstly, we had to develop a simple, quick and reliable method for determination of the stain penetration into the wood. We have found that four modified waterborne stain formulations penetrated significantly less than the original one. Their performance on the industrial scale will be evaluated by further tests. The observed differences between penetration depths of the tested formulations proved that the new method is reliable. However, in order to improve the method, some further investigations will be carried out. We also intend to investigate the influence of wood moisture content on the penetration of the stain. globina penetracije les metode vodno lužilo depth of penetration wood method waterborne stain true false true Slovenski jezik Angleški jezik Članek v reviji 2022-07-29 09:59:19 2022-07-29 09:59:25 2022-09-15 04:16:56 0000-00-00 00:00:00 2007 0 0 Str. 223-225 št. 9/10 Let. 59 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2007-01-01 630*829.12 0024-1067 1606537 RAZ_Pavlic_Matjaz_2007.pdf RAZ_Pavlic_Matjaz_2007.pdf 1 37FB6B58AEC3A8E9C52AB69BCB818CA5 91f577ec4e73672ff9e57be62808b44b0bc6d2747ef9eb34947f9cd1dfe2d3fb 307a7dfc-0f14-11ed-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=158958 Biotehniška fakulteta Les 0 0 0
