Production of insulation panels from cellulose fibers

Pri izbiri plošč za toplotno izolacijo moramo biti pozorni na izolativne lastnosti in vpliv na ugodje samega uporabnika. Izbiramo lahko med umetnimi (mineralna volna, polistiren, poliuretan, penjeno steklo itd.) in naravnimi (lesna vlakna, pluta, kokosova vlakna, slama, celulozna vlakna itd.) toplotno izolacijskimi materiali. Celulozna vlakna se v večini primerov vgrajujejo po sistemu vpihovanja. Ker omenjeni sistem zahteva primerno tehnologijo, smo v nalogi raziskali možnosti drugačne uporabe celuloznih vlaken in sicer v obliki plošč. Izdelali smo 6 različnih plošč različnih debelin z različno gostoto. Izdelali smo plošče debeline med 4 mm in 150 mm ter gostoto 57 kg/m3 in 770 kg/m3. Ugotovili smo, da gostota in debelina značilno vplivata na toplotni prehod. Najboljše izolacijske lastnosti je imela plošča z najnižjo gostoto in največjo debelino, najslabše lastnosti pa plošče z visoko gostoto in majhno debelinoIn the selection of panels for thermal insulation we should take care to insulation properties and the impact on user comfort. We can choose between synthetic (mineral wool, polystyrene, polyurethane, foam glass, etc,) and natural (wood fibers, cork, coconut fiber, straw, cellulose fibers, etc,) thermal insulating materials. In most cases, cellulose fibers are installed with blowing technology. We wanted to determine the effect of thickness and density of cellulose boards made of cellulose fibers. We have produced a variety of 6 plates of different thicknesses between 4 mm and 150 mm and different density, between 57 kg /m3 and 770 kg/m3. We found that the density and thickness, typically affect the thermal transition. The best insulating properties had panel with the lowest density and a maximum thickness, while the worst results were revealed by panels with a high density and a small thicknes
