Vpliv geometrije zobatega spoja in impregnacije na upogibno trdnost dolžinsko spojenega lesa : diplomsko delo - visokošolski strokovni študij = Impact of geometry of finger joints and impregnation on bending strength of longitudinally bonded wood : graduation thesis - higher professional studiesSvetelj, MatjažV domačem podjetju, ki ima stoletno tradicijo obdelave lesa v mizarski stroki, smo v zadnjih letih velik del tehnologije usmerjali v izdelavo lamelno lepljenih nosilcev za znanega kupca. Za ... izboljšanje kakovosti smo proučevali upogibno trdnost dolžinskega spoja lesa v primerjavi z lesom brez dolžinskega spoja. Uporabili smo 2 različni dolžini zobatih vezi (10 mm ter 15 mm). Upoštevali smo tudi različni smeri obremenitve preizkušancev in sicer pravokotno in prečno, glede na orientacijo zobate vezi. Za lepljenje smo uporabili polivinil acetatno lepilo s komercialnim imenom Multibond EZ-1. V testiranje trdnosti smo vključili tudi preizkušance, impregnirane pred postopkom lepljenja z impregnacijskim sredstvom Borosol. Proučili smo možnost impregniranja posameznih lamel že pred izdelavo lamelno lepljenih nosilcev. Kot rezultat bi tako impregnirali kratke lamele, namesto dolgih in težkih nosilcev. V kolikor bi se ta način izkazal kot sprejemljiv, bi omogočil obstoj manjših impregnacijskih postaj; to bi bilo zanimivo zlasti za manjša podjetja, ki se ukvarjajo z lepljenim lesom. Ugotovili smo, da je upogibna trdnost dolžinsko spojenega lesa le nekaj odstotkov manjša od masivnega. Impregnacijsko sredstvo in lepilo sta neprimerna za uporabo v izbrani kombinaciji, saj smo izmerili zelo nizko trdnost dolžinskega spoja impregniranih preizkušancev.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Ljubljana : [M.
