        摘要：A novel scrimber was made of fibrosis veneer（Eucalyptus urophylla）with density from 0.85g/cm3 to 1.20g/cm3.The results showed that the density had a positive effect on water resistance and mechanical properties of the scrimber.The properties tested were superior to solid wood and laminated veneer lumber made of the same materials.

        摘要：Light fastness is an important characteristic of thermochromic wood.The effects of type and dosage of ultraviolet absorber（UV-531 and UV-326）were selected for treating thermochromic wood.The results showed that both of the two ultraviolet absorbers could improve light fastness of the thermochromic wood.Different dosage of UVA had significant influence on the colorimetric parameters of thermochromic wood.UV-326 showed a better effect with optimum dosage of 1.6%.

        摘要：In wooden door production,hardware hole and slot of wooden door leaf were usually processed by multiple procedures,which caused a poor processing accuracy and low productivity.Based on structural characteristics and principles of computerized machining,the authors developed a kind of numerically controlled door lock hole and slot processing machine which could provide loading and unloading door leaf material automatically,automatic bar code identification,automatic door leaf size measurement with compensation and door leaf servo clamping.Using the computerized machine,the processing of hardware hole and slot on both sides of wooden doors leaf were able to finish in a single position clamping.

        摘要：With the growing pressure of carbon emission reduction,the carbon emission from the production process of forest products can not be ignored.Based on the life cycle assessment（LCA）method,the carbon footprint accounting for a tea cabinet was introduced.The results showed that the carbon footprint of the tea cabinet（weight 75kg）is 160kgCO2eq,the main emissions are from the electricity direct emission and other indirect emission;more than 80% of greenhouse gas（GHG）emissions of the tea cabinet processing are from the consumption of painting,lacquer,medium density fiberboard（MDF）and hardware.

        摘要：Free phenol in PF bonded panel was collected by steam distillation and cooking,and the feasibility of the two sampling methods was investigated by the authors.The results showed that the distillation efficiency was low,only a little free phenol was collected within 10 hours by steam distillation method（under 75,85 ℃）,by cooking method（95 ℃）,massive phenol was still not collected after 10 hours and the glue line of PF might be destroyed.It was considered that these two sampling methods were unsuitable for the free phenol collecting from PF resin bonded wood or bamboo panels.

        摘要：For developing low cost sound absorption materials made of wood fiber,the authors analyzed the effects of selected four parameters,such as proportion of wood fiber and polyester fiber,resin consumption,foaming agents content and board density of composite material on sound absorbing coefficients of the composite materials,which were measured by impedance tube instrument.The results showed that the factors had impact on sound absorption coefficient of the samples significantly,and as the fiber ratio of wood and polyester was 3∶1 with 12% resin content,8% foaming agent content and 0.2g/cm3 density,the sound absorption property of the composite samples showed excellent in middle-high frequency with 30% of manufacturing cost saved.

        摘要：Acacia mangiumis one of the tropical plantation species.Since the small diameter of the tree-trunk,and the high proportion of the juvenile wood,it’s easy to cause collapse and internalcheck during drying.A flexible vacuum drying schedule was developed in order to improve drying quality of Acacia mangium lumber.The results showed that compared with conventional drying,the drying rate of flexible vacuum increased considerably,the total drying time of the tested samples from moisture content 64.75% to 10.01% was 42 hours and the drying quality could meet first grade requirement of the national standard GB/T 6491-1999.
