摘要:The author presented the current status and industrial clusters of the wood furniture industry in China.The author also analyzed the characteristics and development trends of the industry and he specifically introduced the status of the wood furniture industry in Shandong province.
摘要:A building system composed of wood-based Structural Insulated Panels(SIPs) provides excellent energy-efficiency and structural performance.Therefore, it is very important to understand characteristics and status of the system to further develop green buildings.The authors reviewed history, advantages, standards and R & D status of the wood-based SIPs and then pointed out future development prospects for reference to relevant industries in China.
摘要:The authors developed a flexible infeed for a China Foma continuous press used for wood-based panel manufacturing.The relationship between the structural characteristics and manufacturing technologies were analyzed for reference in designing a continuous press.Infeed structural characteristics included:discharge length, entry opening, holding position, frame distance, hot-platen opening, pressure system mode, working angle of double steel-belt and flexible conditions.Manufacturing technologies included:mat structure, pre-curing thickness, peak density and panel thickness.

摘要:To explore outdoor applications for Populus scrimber products, the authors prepared a scrimber sample and then evaluated water resistance, decay resistance and anti-insect performance of the scrimber.The results showed that optimum resin impregnation content and density of the Populus scrimber was 14% and 1.05 g/cm3, respectively.Under these conditions, water resistance of the sample could meet the requirements of GB/T 30364-2013 "Bamboo Scrimber Flooring for Outdoor Flooring" with superior MOR and MOE.Without adding any preservatives, decay resistance of the samples could reach Ⅱgrade with moderate termite resistance.

摘要:Poplar specimens(Populus tomentosa)from plantation grown trees were intermittently pressed by a hydro-thermal method to make surface compressed wood.The surface density of the wood was 1.0 g/cm3 with unchanged inner density.The surface compressed wood was then treated with 0.3 MPa of pressurized steam and normal pressure steam, respectively.It showed that the spring ratio of compressive deformation of the wood decreased as treating temperature increased and that the wood treated with pressurized steam performed better than the wood treated with normal pressure steam as far as fixation of compressive deformation was concerned.The thickness change of the wood could be decreased by 67.38% by treatment under 200 ℃ and 0.3 MPa pressure.
摘要:A prototype corrugated bamboo-mat plywood was prepared using a molding process.The influences of moisture contents, resin contents and forming angles in the molding process on mechanical properties and molding performance were evaluated.The results showed that:modulus of rupture(MOR) and maximum compressive load of the plywood decreased with increasing moisture contents, and increased with increasing resin contents.Furthermore, the plywood deformation decreased with increasing forming angles.The optimum conditions for making the corrugated bamboo-mat plywood were determined as 15% moisture content, 15% resin content and 45°forming angle.Under these conditions, the modulus of rupture, maximum compressive load and deformation of the plywood were 46.32 MPa, 81.78 N and 0°, respectively.
摘要:Nano-MgO was used as a catalyst to prepare lignin-phenol-formaldehyde(LPF) resin which was composed of 50% enzymatic hydrolysis lignin.The effects of synthesis parameters were studied including:molar ratio of formaldehyde and phenol(F/P), nano-MgO usage and molar ratio of sodium hydroxide to phenol(NaOH/P) on gel time and storage life of the LPF resin and bonding strength of plywood samples bonded with the LPF resin.The results indicated that optimum manufacturing technology were 1.9 molar ratio of F/P, 1.5% of nano-MgO usage and 0.9 molar ratio of Na OH/P.The gel time of the LPF could be shortened by 30%.The bonding strength of the plywood samples bonded with the LPF resin could meet National Standard GB/T 9846-2015 requirement for I-level plywood.

摘要:In the "New Normal" economic times, traditional labor intensive and mass of stand-alone production mode for edge-glued lumber are facing great challenges, resulting in huge needs to reduce workers, improve timber yield and make customized products.One of the most effective ways in the future to is to use more advanced manufacturing technology and equipment for edge-glued lumber production to replace more operators and make the best use of the wood materials according to natural characteristics.
摘要:Recently, contradiction between customization demands and large scale production of wooden doors were very much eased due to continued improvements in the wooden door manufacturing automation, such as automatic manufacturing processing and equipment innovations.The authors described the new trends in automation manufacturing technology to provide reference for China’s wooden door industry.
摘要:As a new kind of rapid prototyping technology, 3D printing has gradually been applied in various industries.Taking a round-backed armchair as an example, the authors discussed the possibility of applying 3D printing to make a model chair to promote application of the advanced manufacturing technology in the traditional furniture manufacturing industry.
摘要:Gas Chromatography-mass Spectrometry(GC-MS) has been widely used in separation of complex mixtures for its high sensitivity and efficiency.Recently, new methods for wood identification were developed by chemical classification based on GC-MS.In this paper, the authors summarized wood identification research progress based on GC-MS with two different injection methods(direct injection and indirect injection).They also identified some problems that existed for further development trends in wood identification using GC-MS.
