Abstract

In this study, the effect of adding WTR on the physical and mechanical properties of OSB production from Paulownia wood was investigated. Fixed factors of this research are: Strands of Paulownia species with dimensions of 0.20 × 0.8 × 120 mm, Phenol formaldehyde resin (in strands 8% dry weight of strands and in waste tire powder 10% dry weight of tire powder). Laboratory boards with a thickness of 17 mm, dimensions of 40 × 40 cm with a nominal density of 0.5 g / cm3, pressing time was 10 minutes and the pressing temperature was 180 ° C. The OSB were production made of 3 layers (top and bottom layer 25%, and middle layer 50% by weight). The OSB were made of 3 layers (top and bottom layer 25%, and middle layer 50% by weight). Variable factors are: the amount of tire powder was 10, 20 and 30% and the distribution of tire powder particles in 3 layers was scattered in the surface layers, in the middle layer and in all three layers. The mechanical and physical properties of the boards were measured as defined in relevant European standards test methods EN 300. The results of physical properties showed, that increasing the waste tire powder improved the thickness swelling of the boards, so that the minimum amount of thickness swelling in the maximum presence of waste tire powder was 30% and scattered in all three layers. The highest amount of mechanical strength was observed in panels made of 10% tire powder, so that the highest amount of MOR in 10% of tire powder and scattered in all three layers and the highest amount of MOE and IB in The same level of consumption was obtained by dispersing the tire powder in the surface layers.
