| Sumario: | The effect of old corrugated container (OCC) powder as Urea Formaldehyde resin (UF) filler on the properties of medium density fiberboard (MDF) prepared from bagasse fibers and waste MDF was investigated. The variables in this research were the ratio of UF resin powder to OCC (at five levels; 100:0, 5/5:1/98, 97:3, 5/5:4/95, and 94:6) and the ratio of bagasse fibers to waste MDF at five level; 100:0, 98:2, 96:4, 94:6 and 92:8).The constant variable in all treatments were 6 mm/min. press closing time and 150°Cpress temperature. Thickness swelling (TS), water absorption (WA) after 24h, modulus of elasticity (MOR), modulus of rupture (MOE) and internal bonding (IB)) of panels were measured according to EN standard and statistical analysis was performed using SPSS software. The results showed that OCC powder and MDF waste had significant effect on the bending strength and modulus of elasticity. An increase in OCC improved the internal bonding (IB) while IB was reduced by increasing of MDF waste. Minimum water absorption was found in panels with the maximum waste MDF. This means that the panels with 8 percent waste MDF had the least water absorption. Moreover, the panels with highest content of waste MDF had the least thickness swelling. No significant difference was found between the effects of various OCC powder content on the physical. |
