摘要:The present status of research on wood liquefaction technology, in both China and abroad, is reviewed. The importance of developing a liquefaction process for China’s wood industry is also presented. Some possible problems and their potential solutions for the industrialization of wood liquefaction are analyzed and suggested.
摘要:The increased use of products produced with electromagnetic shielding requires the wood industry to adapt this technology for interior wood products. One method would be to apply the chemical plating technology to wood processing. The authors have summarized research advances on the mechanism and application of chemical plating on the wood material. Taking plating copper or gold on wood surfaces as examples, the paper describs the whole process, key technologies and quality appraisal methods of a chemical plating treatment. It is concluded that chemical plating is an applicable technique for wood to gain certain electromagnetic shielding effectiveness, a better decorative effect, and added value.
摘要:Wood/Plastic Composites is a newly developed material and can be used in many fields. Since the interfacial compatibility is one of the key factors in the production and application of wood/plastic composites, the current advances on interfacial compatibilization are reviewed in this paper. This research covered both domestic and foreign literature. With the focus on industrial application, the authors stress that adding compatibilizers in the compounding phase will be more effective than chemical modification on the polarity of a wood surface to improve the interfacial compatibility between the wood and plastic. The authors also point out that further research should focus on developing equipment suitable to normal production of wood based panels, and various compatibilizers that adapt to different species of wood and other lignocellulosic materiales, and plastics under high moisture content condition.
摘要:The authors investigated the applicability of sliced bamboo veneer, as a kind of decorative material and substitution for precious wood materials, to MDF. Results showed that the appearance of MDF could be improved dramatically by overlaying a sliced bamboo veneer on both its top and bottom surface. The optimum parameters of the overlaying technology were determined. It was also found that lining a nonwoven fabric on sliced bamboo veneer would result in decreased surface bond strength for the bamboo veneer overlaid MDF.

摘要:A coating for furniture, cured by ultraviolet exposure, was prepared from E-44 epoxy resin and acrylic acid under an onium salt as catalyst. The curing process of this epoxy acrylate coating was traced to determine the percent conversion of double bonds both by infrared spectrum analysis and chemical titration methods. Comparison of the results from the two methods verified the feasibility of applying IR Spectroscopy to monitoring the curing process of UV-curing coatings on line.
摘要:The shear strength of plantation grown Poplar (Populus euramericana cv. ‘I-214’) was tested from different growth-ring and section positions. The fractured surface due to shearing was observed by SEM to investigate the influence of sampling positions on the shear strength of Poplar logs. The results found that there was a clearly linear correlation between the shear strength and the density in Poplar. Both the growth-ring position and sheared section could influence the shear strength of Poplar. The shear strength increased along the radial direction from the inside to the outside of a log, while the shear strength in the tangential section was higher than that in the radial as well as any inclined section.
摘要:Building on the results of foreign and domestic researchers, the authors have done a series of experiments selecting an effective and environmentally-friendly anti-mould preservative for on-site wood structure protection. The treatment process was also studied. Results showed that under the same environmental conditions, the anti-mould ability of a composition of Pyrethrin and Bardac at 1.5% concentration was the best.
摘要:Cornstalk particles were compressed in a die under different conditions of temperature, pressure and moisture content, and then the creep-time curves were drawn and analyzed. Variance of analysis of the results showed that pressure was the dominant factor affecting the creep of cornstalk particles. The creep reached the highest point under the pressing conditions of 5.6 MPa, 120 ℃ and moisture content of 12%. If pressure and moisture content parameters held constant, the creep at the temperature of 150℃ would be lower than that at 120℃ and 170℃. While fixing temperature and pressure parameters,the creep at moisture content of 14% was less than that at 12% and 16%.
摘要:The influence of a constant temperature and humidity treatment, as well as soaking temperature on thickness swelling (TS) rates for wood-based panels, was investigated in this paper. The results showed that, for medium density fiberboard (MDF) and particleboard, their thickness swelling rates increased when the soaking temperature was increased, and there was a linear relationship between them, whereas, plywood was influenced little by the soaking temperature. Also studied was whether treating the specimens in a constant temperature and humidity condition before soaking would influence TS test results. It was also found to be essential to give a conditioning treatment for particleboard and thin MDF to ensure correct test results.

摘要:The authors introduced the concept of the Enterprise Resource Planning System (ERP) and explained the necessity of applying a management information system to Chinese furniture manufacturing companies. Under the guidance of ERP theory and based on C/S (Client/Server) structure, the authors developed a management information system for furniture manufacturing companies. A blue print for the design work flow and main functional modules of the system were described. The anthors also presented the details of technological design for the software.

摘要:The authors have designed a management system for wood specimens by applying Microsoft Visual Basic 6.0 language. Functional modules of the system include retrieval, input, statistics, printing and maintenance. The system could also be adjusted to the management of other specimens of trees, plants, animals and insects, etc.

摘要:The author made an analysis of a production line for tannin adhesive. The study analyzed the main procedures such as preparing, measuring, synthesizing and automatic controlling processes. It also provided suggestions on actual technological design.
摘要:To improve fire-resistance of high-pressure laminates (HPL) made from thermosetting resin impregnated papers, an organic compound of phosphorus was added to the phenol-formaldehyde resin. Depending on whether the phosphorus compound was added before or after the preparation of PF resin, it acted as a reacting flame retardant or an additive flame retardant respectively. Results found that superior fire resistance resulted when it acted as a reacting flame retardant. When used as an additive flame retardant, the fire-resistance of the HPL increased as the level of phosphorus compound increased. When the amount was beyond 7% (on the absolute dry weight of PF resin), the HPL no longer supported combustion.

摘要:The paper presents continuing research on manufacturing parquet with Chinese Fir (Cunninghamia lanceolata). Previous three-layer parquet was made from precious hardwood veneer on the surface, ordinary hardwood veneer in the core and Chinese Fir lumber on the bottom layer. To decrease the wood consumption and production cost, the authors made a modification in the manufacturing technology by choosing plywood overlaid with precious veneer as the face layer to make parquets with Chinese Fir lumber. It was found that this new kind of parquet manufactured with the modified technology not only has the same excellent physical and mechanical properties as the former parquet, but also the production cost could be reduced by 30 percent.
