- 摘要：The authors made bamboo-fiber based composites with bamboo obtained from a factory. The composites had densities between 0.85 to 1.20 g/cm3 using cold-pressing and hot-pressing methods. The major mechanical and physical properties of these composites were tested. The results showed that both cold-pressing and hot-pressing methods produced composites with high physical and mechanical performance. The composites produced by cold-pressing had better water resistance than those produced by hot pressing. However, the composites produced by hot-pressing had higher bending and shear strengths.关键词：bamboo-fiber based composite;cold pressing;hot pressing;water resistance;mechanical properties

- 摘要：The authors studied the effects of the percentage and the size of wood flour on the viscosity and sedimentation of polyurethane wood filler used for furniture products. The results showed that: the viscosity of polyether composition increased when the m（wood flour）∶m（polyether polyols） greater than 7∶100 or the wood flour size was less than 80 mesh.The wood flour sedimentation rate decreased when the wood flour percentage or mesh size increased.关键词：polyurethane;imitation-wood;wood flour;dispersion;sedimentation

发布时间：2021-02-08 - 摘要：The authors evaluated the cutting force influence of rake angle, cutting thickness and cutting speed to provide the basis for rational design and use of circular saw blades on Chinese fir, Mongolian pine and Manchurian ash specimens. The results indicated that the principal and perpendicular cutting forces decreased with increasing rake angle and cutting thickness. It was also observed that cutting speed had little impact on principal and perpendicular cutting forces. The optimal cutting parameter settings for different wood species were proposed.关键词：wood;cutting force;cutting parameters;rake angle;cutting thickness;cutting speed;circular saw blade

发布时间：2021-02-08 - 摘要：The smoke inhibiting property of FRW-C1 and FRW-C2, two new fire retardants in the FRW series for wood, were systematically studied using a cone calorimeter. The results show that the values of smoke ratio （SR）, specific extinction area （SEA）, the concentration of carbon dioxide （CO2）, and the production of carbon dioxide （PCO2） of FRW-C1 and FRW-C2 treated Korean pine samples decreased when compared with the untreated samples. The FRW-C1 and FRW-C2 treatments had a minor influence on the generation of carbon monoxide.关键词：wood fire retardant;FRW fire retardant;cone calorimeter;smoke inhibition

发布时间：2021-02-08 - 摘要：To explore new opportunities of utilizing salix （of the willow family） wood, the authors made salix-based composite panels, overlaid with PF impregnated paper faced veneer or PF impregnated fiberboard, for a concrete molding application. They investigated the effect of processing conditions on the composite’s performance. The results showed that the optimal process conditions were: 12% adhesive and 160 ℃ press temperature for 0.9 min/mm panel thickness. The salix panels produced under these optimal conditions had performance similar to the specifications of comparable products.关键词：Salix;recompose;overlay;Concrete form;physical and mechanical properties

The results indicate that bamboo mold inhibition can be improved with increased γ-ray intensity. This new method is expected to become the new treatment to improve performance of bamboo products.关键词：γ-ray;radiation intensity;bamboo;mold inhibition

Research & Development
- 摘要：Both domestic and international standards for wood structures were reviewed and several key issues for improving Chinese standards, especially for the Code for Design of Timber Structures to be consistent with the international standards, were identified. The authors suggested that the standards for industrialized wood products and the standards for design of wood structures should be separately established. Wood of various species needs to be stress-graded and identified with its characteristic strength; the reliability of wood structures and the derivation of the design strengths of wood need to be further verified and the specifications of the reliability and strength values need to clarified; calculations of resistance of wood members and load-bearing capacities of the connections need to be necessarily improved and modified; and the contents of codes need to be reasonably selected and arranged.关键词：wood structure;code;standard;Wood product

Discussion & Suggestion
- 摘要：In order to improve the surface properties of reconstituted decorative poplar flooring, the authors impregnated the flooring in water-soluble low molecular phenol-formaldehyde（PF） resin and then hot-pressed it. The results indicate that longer impregnation time improves surface abrasion resistance, impact resistance, surface hardness, and bending performance. It was noticed that phenol-formaldehyde resin with magnesium oxide and silicon dioxide can improve the wear resistance and impact resistance of the flooring.关键词：Poplar;reconstituted floor;impregnating treatment;surface strengthening;PF resin

发布时间：2021-02-08 - 摘要：Manglietia glauca drying characteristics were investigated using 100 ℃ constant temperature. The results showed that Manglietia glauca was relatively easy to dry with a Grade 2 drying speed. It was noticed that the main drying defects included initial checks and distortions （from grades 2 and 3）, and cross-section deformation （between grades 1 and 2）. No internal cracks were found in this study and there was little shrinkage difference between tangential and radial directions. Based on these results, a drying schedule for 20～30 mm thick Manglietia glauca was proposed.关键词：Manglietia glauca;Drying characteristics;100 ℃ drying method

发布时间：2021-02-08 - 摘要：Organic wood-flour putty was prepared by mixing wood-flour, polyvinyl acetate emulsion （16% solids content） and isocyanate resin. Wood flour with different diameters, from 10 to 60 μm, made from waste wood was used. This article discusses how the putty performance can be influenced by the wood flour size. The results show that with a specific formula, wood-flour putty made with 500 mesh flour has better painting properties and adhesive strength.关键词：wood-flour putty;wood flour;size;painting property;adhesive strength
