China southern plantation - Laminated veneer lumber - Optimal production - Process pressure - Process time - Production technology
In order to select the optimal production technology for laminated veneer lumber of wood bridge, the properties and mechanics of experimental samples made by China southern plantation were analyzed. The experiment results showed that: the best production technology mode was 1.6min/mm hot process time, 4 MPa hot process pressure and 25 mm board thickness. And the eucalyptus veneers were fit to make laminated veneer lumber for wood bridge.

The luminescence properties of Ba3BP3O12 doped with divalent Eu2+ are investigated in the temperature range 10-525 K. Excitation and emission bands corresponding to f-d transition of Eu2+ from two crystallographic sites are identified. The PL spectra of Ba2.99Eu0.01BP3O12 sample at low temperatures further imply that the Eu2+ emission emanates from two different crystallographic sites for EU2+ ions. The temperature dependence of emission intensity and lifetimes are studied. The luminescence intensity of Eu II does not have drastic decrease in the temperature range between 10 and 300 K, while that of Eu I decreases dramatically. Unfortunately, Ba2.99Eu0.01BP3O12 sample has poor thermal stability at temperatures higher than 300 K. The quantum yield, activation energy and thermal quenching mechanism of the luminescence are also discussed. (C) 2015 Elsevier Ltd and Techna Group S.r.l. All rights reserved.

Bamboo is so easy to moulding that bamboo products haven't been high value added utilization. Therefore, the effect of wood extractives molecules on bamboo biology moulding was studied based on full-factor test. The result is: (1) The effect of tree species of wood extractives on bamboo biomass moulding was highly remarkable. The effect of treatment time on bamboo biology moulding was not remarkable.(2) The better anti-mold effects of wood extractives were Cassia siamea, Cunninghamia lanceolata, Eucalyptus urophydis, Populusdeltoides in turn. So this pointed out the direction for the development of the biologic mould inhibitor.

Moldy wood can cause some skin disease. However epoxy resin adhesive (EP) can inhibit mold growth. Therefore, antibacterial EP/wood biocomposites were reinforced and analyzed by the nonlinear finite element. Results show that glass fiber cloth and aluminum foil have the obvious reinforced effect under flat pressure, but this was not the case under side pressure. And when the assemble pattern was presented in 5A way, the strengthening effect was better. The nonlinear finite element showed that the aluminum foil and glass fiber cloth have the obvious reinforced effect. The mutual influence and effect of span, thickness and length on the ultimate bearing capacity of specimen were studied. And the simulation results agreed with the test. It provided a theoretical basis on the preparation of antibacterial EP/wood biocomposites against skin disease. (C) 2015 The Authors.
