        摘要：Three kinds of aliphatic alcohols（1-dodecanol,1-tetradecanol,and their mixtures）were selected as solvents to prepare a coloring agent for making thermochromic wood.The colorimetric parameters of the thermochromic wood and the relationship between the solvents melting point and thermochromic properties of the wood were analyzed.The results showed thermochromic property differences existed among the thermochromic wood made with different solvents.The color-change temperature depended on the melting point of solvent.The wood made with solvent with lower melting point,such as 1-dodecanol or mixture of 1-dodecanol with 1-tetradecanol,could have color change at lower temperature.

        摘要：High density polyethylene（HDPE） film was used as adhesive to make formaldehyde-free Poplar plywood.Response Surface Methodology（RSM） was used to optimize the processing technology for the plywood.The authors found that the bonding strength of the plywood was affected greatly by pressing temperature,pressing time as well as the film usage.The interaction effects between the pressing temperature and time were significant.The plywood bonding strength could reach 1.68 MPa under the optimum processing conditions as following:152 ℃ of pressing temperature,1.1 mm/min of pressing time,264.92 g/m2 of film usage,and could meet the requirement for type II plywood according to the National Standard of GB/T 9846.3-2004.

        摘要：Fire resistance of wood samples treated with boron-based wood preservative（D-B-M） were tested by a cone calorimeter.The preservative was a mixture of disodium octoborate tetrahydrate（DOT）,boric acid（BA） and magnesium sulfate（MgSO4）.Testing results indicated that there was a synergistic effect among the mixed components.The heat release rate,total heat release and the yield of CO2 of D-B-M treated samples decreased considerably.

        摘要：Influence of butt joint gap in ultra-long laminated bamboo sliver lumber（LBSL）from Moso bamboo（Phyllostachys pubescen）was studied.The effects of gap depth and position were analyzed by determining the LBSL bending performance.The results showed that LBSL bending performance decreased with the gap on the surface gradually deepened.The butt joint gap had no obvious effect on the LBSL bending performance only when the gap depth was less than 5% of the total lumber thickness.The closer of the gap position near the lumber core,the less influence of the gap position had on LBSL bending performance.It was concluded that for making LBSL,butt joint gap should be avoided in forming process,especially no gap should be allowed on the surface.
