20.500.12556/RUL-164381 Iverne plošče in lesno-plastični kompoziti iz smrekovih in bukovih skobljancev Particle boards and wood-plastic composites made from spruce and beech planer shavings Namen te magistrske naloge je bil izdelati uporabno trislojno, izolativno in WPC (wood-plastic composite) ploščo iz lesnih skobljancev. Najprej smo izdelali enoslojne plošče iz posameznih lesnih vrst (smreka in bukev) in različnih velikosti skobljancev. Glede na lastnosti teh plošč smo nato oblikovali enoslojne plošče z mešanimi skobljanci, ozirajoč na te lastnosti pa smo na koncu izdelali dva tipa trislojnih plošč (eno z mešanimi skobljanci v slojih in drugo z eno lesno vrsto v posameznem sloju). Rezultati so potrdili, da je mogoče iz skobljancev izdelati plošče, ki po mehanskih lastnostih presegajo standarde za pohištvene plošče P2. Najboljše lastnosti so bile opažene pri trislojnih ploščah, kjer so bili v posameznih slojih uporabljeni gradniki iz ene same lesne vrste, uporabne pa so bile tudi tiste z mešanimi sloji. Kot največja slabost izdelanih plošč se je izkazal debelinski nabrek ob vpijanju vode, a bi se ga verjetno dalo izboljšati z večjim deležem lepila in dodajanjem parafinske emulzije. The purpose of this master's thesis was to create a functional three-layer, insulating, and WPC (wood-plastic composite) board made from shavings. We first produced single-layer boards from individual wood types (spruce and beech), and based on the properties of these boards, we then made single-layer boards with mixed shavings structure. Considering these properties, we finally created two types of three-layer boards - one with mixed wood shavings in the layers and another with one wood type per layer. The results confirmed that it is possible to make boards from wood shavings that exceed the mechanical property standards for P2 furniture boards. The best properties were observed in the three-layer boards, where each layer was made from a single wood type, though the mixed-layer boards were also usable. The greatest weakness of the manufactured boards was the thickness swelling upon water absorption, but this could likely be improved by increasing the adhesive content and adding hydrophobic agent. lesni ploščni kompozit skobljanci iverne plošče WPC izolacijske plošče upogibna trdnost razslojna trdnost debelinski nabrek vpijanje vode gostota wood-based composite panel planer shavings particle boards WPC insulation boards bending strength delamination strength thickness swelling water absorption density true false false [R.
