        摘要：Effects of aperture diameter, perforative ratio and thickness of perforated panels made of eucalyptus plywood on acoustic absorption properties of the panel were studied. The results showed that thickness and perforative ratio had significant impact on acoustic absorption properties of the panels. The perforated acoustic panels with 18 mm panel thickness, 3 mm aperture diameter and 14% perforative ratio showed good acoustic absorption properties. Average sound absorption coefficient of the panels could reach 0.5 in the range of 1006 300 Hz of acoustic frequency but the panel had the best acoustic absorption performance at 1 700 Hz acoustic frequency.

        摘要：Various mass ratios of bamboo fiber（BF）and wood fiber（WF）were used to prepare BF/WF/PP composites with 50% of Polypropylene（PP）fiber.The effects of BF on physical and mechanical properties,as well as the micro morphology of the composites were investigated.The results showed that the water resistance of the composites samples was enhanced with higher percentage of BF.The composites with 25%BF showed the best mechanical properties.Optimized mass ratio of bamboo/wood fibers was BF∶WF=25∶25.The properties of the composite samples meet the requirements of TL 52448-1998.

        摘要：Wood-based structural insulated panels（SIPs） were prepared with oriented stranded board（OSB） or structural plywood as face panels and polyurethane insulated board as the core board. Mechanical properties of the SIPs were investigated.The results indicated that the mechanical load of the SIPs samples could meet requirements of ANSI/APA PRS 610.1-2013 standard.Ultimate load of the SIPs faced with structural plywood was higher than that faced with OSB.The ultimate load increased with increased thickness of the core board.Polyurethane insulation board could be used to replace polystyrene insulation board（EPS）as core board to prepare SIPs.

        摘要：To develop new wood preservatives, inhibition effects of rutin and its metal complexes（rutin-copper, rutin-zinc, rutin-manganese and rutin-magnesium） on brown-rot fungi（Gloephyllum trabeum） and white decay fungi（Coriolus versicolor） were studied using the growth rate method. Results indicated that rutin and its metal complexes had inhibition effects on the two decay fungi and that the antifungal activity increased with increased concentration. Rutin, rutin-copper and rutin-zinc could basically restrain growth of the two decay fungi at 6.66 mg/mL of concentration while rutin-manganese and rutin-magnesium substantially inhibited growth of the two decay fungi at 9.99 mg/mL of concentration. Rutin, rutin-copper and rutin-zinc could be used for preparing environmentally-friendly wood preservatives in the future.

        摘要：In order to develop formulations of paraffin wax/silane emulsion for wood modification, an orthogonal test was designed to determine the effect of alkoxysilane chain length and ratio of wax to silane. This test also studied hydrophile-lipophile balance（HLB） value and content of surfactant on stability and particle size of the paraffin wax/silane emulsion. Moreover, water repellent efficiency of wood samples treated with different paraffin wax/silane emulsions was also determined. The results indicated that the optimal emulsion formulation was found with 2∶1 ratio of wax to silane as well as 13.5 of the HLB value and 6% of the surfactant content. The emulsion reached stability grade 1 with 195.7 nm average particle size and 27.3% water repellent efficiency of the wood samples achieved after 384 h immersion.

        摘要：Nanocellulose, the most abundantly renewable natural polymer material with excellent performance, has become one of the key points in nanotechnology research. Cellulose-based nanomaterials have excellent features such as superior chemical and electrochemical stability, excellent mechanical strength and stiffness, large surface area and light weight, as well as wide availability, renewability and biodegradability. The authors reviewed preparation of nanofibrillated cellulose, nanocrystalline cellulose and bacterial cellulose and summarized research progress in microcapsules applications. Future research and development of nanocellulose in practical microcapsules applications were also presented.

        摘要：To manufacture a surface decorated blockboard with extra-low formaldehyde emissions, the authors selected no-added formaldehyde(NAF) blockboards as substrate materials and E0 level impregnated papers as surface decorative materials. Effects of hot-pressing time and temperature on formaldehyde emissions from the samples were analyzed.The results indicated that extending hot-pressing time or increasing temperature had little effect on the formaldehyde emissions and that it was almost impossible to further reduce formaldehyde emissions from the samples to zero-emission level by hot pressing.

        摘要：Tracking-Learning-Detection(TLD) was used to detect surface defects of particleboard on line. The results showed that the TLD algorithm method accurately recognized and tracked large wood particles on the surface of the particleboard and, by calculation, detected surface defect characteristic parameters. The TLD algorithm was shown to be useful as a surface defect detection method for particleboard testing with high accuracy, real-time performance and robustness.
