| 520 | |a In this study, the effect of mat moisture content on the physical and mechanical properties of particleboard was investigated. The experimental boards were produced by using 40 % softwood, 45 % hardwood chips, and 15 % sawdust. The formaldehyde resin/adhesive was used in three-layers (bottom-top layer 12 %, core layer 8 %). Multi-opening press was used during manufacturing the experimental particleboards. The physical and mechanical properties of boards obtained were identified according to the TS-EN standards. The optimum core layer moisture content was determined as 6 % and 7 % according to the results, whereas the moisture content of bottom and top layers was 14 %. Under these moisture content conditions, the bending strength was found to be 13.3 N/mm², the modulus of elasticity in bending 2466 N/mm², and internal bonding strength 0.44 N/mm². The optimum bottom-top layer moisture content was determined to be between 13 % and 15 % and 6.5 % for the core layer. | ||
| 520 | |a U radu je istraživan utjecaj sadržaja vode u slojevima ploča od sitnjenog drva na njihova fizička i mehanička svojstva. Istraživane su ploče proizvedene od iverja mekog drva u udjelu 45 %, iverja tvrdog drva u udjelu 15 % i drvne prašine u udjelu 15 %. Ploče su se sastojale od tri sloja u kojima je upotrijebljena formaldehidna smola/ljepilo (u vanjskim slojevima 12 %, u središnjim slojevima 8 %), a prešanje je obavljeno višeetažnom prešom. Fizička i mehanička svojstva ploča određena su prema TS-EN normama. Iz dobivenih je rezultata utvrđen optimalan sadržaj vode u središnjem sloju od 6 i 7 %, dok je konstantni sadržaj vode u vanjskim slojevima iznosio 14 %. Pri tim sadržajima vode dobiveni su ovi rezultati: čvrstoća na savijanje 13,3 N/mm2, modul elastičnosti 2466 N/mm2 i međuslojna čvrstoća 0,44 N/mm2. Utvrđeno je da je optimalan sadržaj vode u vanjskim slojevima između 13 i 15 %, a u središnjem sloju 6,5 %. | ||
