Vpliv dodanega tanina na lastnosti lepila iz utekočinjenega lesa : diplomsko delo - univerzitetni študij = Influence of tannin aditive on the adhesive properties of liquefied wood : graduation thesis - university studiesTratar, Klemen, 1987-S težnjo po celostni izrabi lesne surovine se veliko raziskav usmerja v izdelavo utekočinjenega lesa in njegovo rabo v različnih aplikacijah. Ker je lepljenje ena izmed pomembnejših faz v lesarstvu, ... smo poizkušali narediti novo lepilo na osnovi utekočinjenega lesa po trenutnih ekoloških trendih. Preizkusili smo različne kombinacije lepilnih mešanic na osnovi utekočinjenega lesa z dodatkom tanina in formalina. Kakovost lepil smo preverjali z ugotavljanjem strižne trdnosti lepilnega spoja. Lepilo iz čistega utekočinjenega lesa je doseglo 64,5 % zahtevane trdnosti v trajnostnem razredu C1. Ugotovili smo, da z dodajanjem tanina le znižujemo trdnost in pospešujemo dovzetnost razpada lepilnega spoja v stiku z vodo. V lepilu je tanin očitno deloval zgolj kot polnilo, saj ni bilo izboljšanja trdnosti lepilnega spoja. Z namenom po doseganju višjih strižnih trdnosti smo nadaljnje preizkuse omejili na lepilne mešanice utekočinjenega lesa in formalina. Koncentracije smo zviševali vse do 50 % deleža formalina in dosegli 77 % zahtevane trdnosti po trajnostnem razredu C1. Ugotovili smo, da formalin delno izboljša odpornost lepilnega spoja na delovanje vode in skrajšuje odprte čase lepilne mešaniceType of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [K.
