        摘要：Commercial oriented strandboards were overlaid with bamboo sheets in the form of woven mat or curtain and the main physical and mechanical properties of overlaid boards were measured The influences of overlay materials, resin application methods and assembly patterns were analyzed by comparing the properties of different overlaid boards with that of OSB The results showed that the overlaid boards were superior to OSB in main physical and mechanical properties and also in strength retention after aging (2 hour’s immersion in boiling water) Under the experimental conditions of this research, i e , resin application amount 200 g/m 2, hot pressing temperature 160℃, hot pressing time 6 minutes with a pressure of 1 5 MPa,the bonding strength between bamboo sheets and OSB was higher than that of the internal bond of OSB The thickness swelling of overlaid boards was reduced to about 1/3 of that of OSB The strength and stiffness of overlaid boards were depending greatly on the sheet forms and assembly patterns, nevertheless the resin application methods (spreading or impregnating) had little influence, As to the modulus of rupture and elasticity, the overlaid board with bamboo curtains were parallel to OSB was the best in the parallel direction, but it’s MOR ⊥ and MOE ⊥ were lower than that of OSB When the OSB was overlaid with bamboo woren mats or with curtains perpendicular to OSB, the  MOR and MOE both in parallel and perpendicular direction were elevated greatly

        摘要：In this study, poplar, larch and Portland cement was used as main raw materials for making cement bonded particleboard(CBP), and a series of experiments was conducted to investigate the curing process of CBP by carbon dioxide injection. In addition, effects of density, particle/cement ratio, water/cement ratio, gas pressure, injection time, etc. on properties of the board were examined, respectively. The results showed as follows: (1) The optimum technological parameters of manufacturing CBP were CO 2 gas pressure of 0.7 MPa; injection time of 3 minutes; particle/cement ratio of 0.2(poplar) or 0.5(larch); water/ cement ratio of 0.35(poplar) or 0.4(larch). (2) Water/cement ratio not only determined the possibility of board formation but also greatly influenced the reaction characteristics and the mechanical properties of CBP. (3) Carbon dioxide pressures between 0.5￣0.8 MPa slightly affected the mechanical properties of CBP, but intensely influenced the reaction characteristics of cement and carbon dioxide. (4) Curing conditions were closely related to the ultimate strength of the board. The curing conditions with sufficient water and alkaline contents could improve the properties of the board. (5) Carbon dioxide injection could reduce or eliminate the detrimental cement curing inhibition of wood extractives. (6) Properties of the CBP showed a great difference from that of conventional CBP.
