20.500.12556/RUL-101 Vpliv parametrov stiskanja na nekatere lastnosti obložene iverne plošče diplomsko delo (visokošolski strokovni študij) Influence of pressing parameters on some properties of the surfaced particle board graduation thesis (higher professional studies) Raziskovali smo vpliv parametrov stiskanja (temperature, časa in tlaka) pri kratkotaktnem postopku oblaganja iverne plošče z dekorativnimi papirji na nekatere lastnosti površine obložene iverne plošče (stopnjo otrdelosti, odpornost na paro, odpornost na razenje). Uporabljeno trislojno iverno ploščo debeline 16 mm in impregniran dekorativni papir gramature 80/180 g/m2 smo pridobili iz industrijske proizvodnje. Plošče smo stisnili na laboratorijski stiskalnici. Ugotovili smo, da temperatura in čas stiskanja vplivata na vse opazovane lastnosti, medtem ko tlak stiskanja vpliva le na odpornost na razenje. Stopnja otrdelosti in odpornost na paro se na spremembe parametrov odzivata približno enako. Na odpornost na razenje vplivajo vsi opazovani parametri stiskanja. Pri najvišjih in najnižjih vrednostih parametrov lastnost površin obloženih plošč ni bila več zadovoljiva. In a short cycle process using impregnated decorative paper (80/180 g/m2), the influence of pressing parameters (temperature, time, pressure) on some particleboard surface properties (degree of hardening, resistance to steam, resistance to scratching), was researched. 3 layer particleboard (16 mm thick), so as the decorative paper were obtained from the industial production. Tested boards were pressed on a laboratory press. It was found that temperature and pressing time have influence on all the researched properties of surfaced particleboards. Pressing pressure has its influence only on resistance to scratching. The degree of hardening and resistance to steam respond to changes of pressing parameters in the same way. All the researched parameters influence the resistance to scratching. By the highest or lowest value of the pressing parameters the quality of surfaced particleboards wasn't good enough. iverna plošča melaminska smola lastnosti površine razenje particle board melamine resins surface properties scratching true false false [M.
