        摘要：Based on monotonic loading and step loading test methods, shear strength of five types of cross-laminated timber（CLT） connected with self-tapping screws（STS） were tested. Testing results showed that increasing length and diameter of STS could significantly improve CLT shear strength. CLT shear strength with an STS 45 degree inclination angle was 28.3% higher than that of the CLT with an STS 30 degree inclination angle. The connection assembly with double fastener inclination showed a better shear strength, which was 50.7% higher than that with half-lapped joints.

        摘要：In order to develop environmentally-friendly wood modification methods,water soluble vinyl monomers,2-hydroxyethyl methacrylate（HEMA）and N-methylol acrylamide（NMA）were used as modifiers to treat poplar wood from plantation forests.Effects of addition ratio and concentration of the modifiers on performance of the treated wood were investigated.Results showed that 40.46%of weight percent gain（WPG）,60.77%of anti-volume swelling efficiency（ASE）,20.19%of modulus of rupture（MOR）and 38.00%of modulus of elasticity（MOE）of the treated samples were obtained by optimum treatment processes such as 80∶20 of HEMA/NMA addition ratio and40%of modifiers concentration.Therefore,wood modification could be conducted under lower treatment temperature with less modifier usage,compared to traditional modification methods.

        摘要：A kind of wood-plastic composites（WPCs）was made from hemp fibers and polypropylene（PP）fibers.Effect of density and ratio of the hemp fibers to PP fibers on physical and mechanical properties of the WPCs samples were investigate.The results showed that increased mechanical properties and improved water resistance of the WPCs were observed with increasing WPCs density and reduced hemp fibers usage.The mechanical properties of the WPCs with 0.8 g/cm3 in WPCs density and 3∶7 in ratio of the hemp fibers to PP fibers could meet requirement for furniture and decoration in standard DB 44/T 349-2006.Water proof performance of the WPCs needs to be further improved.

        摘要：The layer-by-layer（LbL） assembly method comes to the fore in many methods of preparation of nanocellulose-based functional composites for it possesses many advantages such as simple principle, easy operation and adjustable structure. Herein, the principle and existing approaches of the LbL assembly technique were presented. According to the role that nanocellulose plays in functional nanocomposites, three parts were then divided to elaborate preparation technics, structural and functional characteristics. Future research and development of the LbL assembled nanocellulose-based functional composites were proposed.

        摘要：Laminating floor is the largest sales volume product among all kinds of floor products in China. But national standards for the product have not been revised and updated for ten years while European standards for the laminating floor product was updated to 2016 version. Difference between Chinese national standard GB/T 18102-2007 and European standard EN 13329:2016 were compared and analyzed for reference to revision of Chinese national standard for laminate floor.

        摘要：Air source heat pump systems have gradually become the first choice for wood drying heating systems under pressure from environmental protection and rising costs in recent years. Drying schedules for 20 mm thick Umbila Lumber, based on a heat pump system, were obtained by pretest and production optimization tests for reference to wood drying processing.

        摘要：Conventional drying of wood consumes a lot of heat energy and most of the energy is discharged through ventilation, which results in serious energy waste. A trial production experiment was carried out with dehumidification in a conventional dry kiln. The experimental results showed that energy consumption for the combined drying could be reduced by 60%, compared to conventional drying.
