Vpliv impregnacije z baker-etanolaminskimi biocidnimi proizvodi na vodoodbojnost in sorpcijske lastnosti lesa : diplomski projekt = Influence of impregnation with copper-ethanolamine preservatives on water repellency and sorption properties : B. Sc. thesisKolmanič, KlemenImpregniran les je izpostavljen različnim biotskim in abiotskim dejavnikom, zato nas je zanimalo, kako se spreminjajo lastnosti lesa med uporabo. Smrekove, borove (beljava) in macesnove (jedrovina) ... vzorce dimenzij (1,5 % 2,5 % 5,0) cm3 smo impregnirali s komercialnim biocidnim proizvodom Silvanolin, dveh različnih koncentracij cCu = 0,25 % in cCu = 0,5 %. Vzorce smo impregnirali po štirih postopkih: postopek potopa vzorcev v zaščitno sredstvo za 8 h, postopek potopa vzorcev v zaščitno sredstvo za 24 h, vakuumski postopek impregnacije in vakuumsko tlačni postopek impregnacije. Določanje sorpcijskih lastnosti smo razdelili na dva dela: navzem tekoče vode in navzem vodne pare. Navzem tekoče vode smo določali: s kratkotrajnim postopkom kapilarnega navzema, s potopom vzorcev v vodo za 24 h in z določanjem hitrosti vpijanja kapljic vode v les z goniometrom. Za določitev navzema vodne pare: smo uporabili uravnovešanje vzorcev v komori s 100 % relativno zračno vlažnostjo in z naknadnim sušenjem vzorcev v komori nad silikagelom. V večini primerov smo ugotovili, da so pri impregniranih vzorcih ravnovesne vlažnosti višje, kot pri neimpregniranih preskušancih in, da impregnirani vzorci vpijejo več vode, kot vzporedni kontrolni vzorciType of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
