        摘要：In order to provide a theoretical basis for designing and processing perforated medium density fiberboard（perforated MDF）for sound absorption,the effects of hole diameter,perforation rate and cavity depth behind the perforated MDF were evaluated by impedance-tube transfer function method.Under the following optimum conditions,such as 15 mm thickness,3.14% 4.91% perforation rate and 50 mm cavity depth behind the perforated MDF,the maximum sound absorption coefficient for perforated MDF could reach 0.6.

        摘要：Derived from a renewable,biodegradable and environmentally friendly resource,soy protein adhesive（SPA）has been widely considered for a long time.The objective of the study was to evaluate thermal and bonding characteristics of SPA used in plywood manufacturing.At a heating rate of 20 ℃/min,the SPA samples totally cured at 157 ℃ and thermal degradation began at173 ℃.Testing results showed there was a positive linear correlation between glue consumption and bonding strength of the SPA bonded plywood samples.When the SPA plywood samples were made with 450g/m2 glue consumption（two sides）under 1.6 MPa pressure at 160 ℃ for 80s/mm,the wet bonding strength of the samples reached 0.78 MPa,which met the specification requirement of the National Standard GB/T 9846.3-2004 for typeⅡplywood.

        摘要：Chinese fir（Cunninghamia lanceolata）plantation lumber was treated with steam at atmospheric pressure,pressurized with super-heated steam and saturated water vapor,respectively.The dimensional stability,mechanical properties and color change of the treated samples were evaluated.The results showed that color changed the least for the samples treated with steam at atmospheric pressure,while the dimensional stability of the samples treated with pressurized super-heated steam had the greatest increase but the mechanical properties decreased.The samples treated with saturated water vapor,though,caused darkest color,the worst splits and the lowest strength.

        摘要：The effects of iodopropargyl carbamate（IPBC）and decyldimethyloctylammonium chloride（DDAC）used for rubberwood protection from mould and blue stain were studied.The results of laboratory tests showed that rubberwood samples treated with IPBC or IPBC+DDAC compound,respectively,had good resistance to mould and blue stain fungi,but IPBC+ DDAC compound was more effective than IPBC alone.In the first two months of field tests,the percentage of infestation area on rubberwood specimen surfaces was less than 10% when treated with 0.2%solution under a vacuum pressure process,or 0.3% solution using an immersion treatment.All the samples tested could reach the requirements for rubberwood storage and sawing process before drying.
