        摘要：The authors developed a bonding technology for glued laminated timber made with Cryptomeria fortune lumber to make non-structural glued laminated lumber.The lumber was tested for shear strength, wood failure and delamination ratio. The results indicated that Cryptomeria fortunei lumber can be used in non-structural applications.The optimum bonding process was as follows:1.0 MPa press pressure,30 min press time,180g/m2 glue consumption,and a tangential face assembled with another tangential face（T-T）.Under the optimum bonding process,the bonding properties of glued laminated timber made with Cryptomeriafortunelumber met the Japanese Agricultural Standard JAS SE-8requirement.

        摘要：CaO,MgO,ZnO and BaO were used as catalysts to make phenol-urea-formaldehyde（PUF）resins.The molar ratio effects of formaldehyde to urea plus phenol,molar ratio of sodium hydroxide to phenol,and adding stage,adding amount and type of divalent metal oxide on panel bonding strength,gel time and pot life were evaluated and optimized through orthogonal experimentation.The results showed that divalent metal oxides as catalysts were effective to make fast curing PUF resin with shortened gel time compared with the control resin.The optimized parameters were 0.50% ZnO of phenol mass added at the reaction beginning with 2.0molar ratio of formaldehyde to urea plus phenol and 0.6molar ratio of sodium hydroxide to phenol.

        摘要：In order to find an activating method for rice straw board,the authors used sodium hydroxide solutions with pH values from 8to 14 to treat rice straw board specimens.Surface absorption properties of the specimens treated with three kinds of liquids（distilled water,glycerin and alcohol）were tested.The results showed that the surface absorption properties of the treated specimens were all improved with increasing the pH value of the solution.Optimum pH value of sodium hydroxide solution for treating rice straw board was 711.

        摘要：The authors conducted an experiment to evaluate the heat treating temperature and time effects on Pinus sylvestris wood to control its color.The CIE standard colorimetric system was used to characterize wood color and FT-IR was used to analyze functional groups of the heat-treated wood.The results showed that the color change of the heat-treated Pinus sylvestris wood was primarily attributed to brightness change.As the heat treating temperature and time increased,chromophore groups increased in the wood,which enhanced the wood absorption ability to visible lights,resulting in a darker color and a decreased brightness.The authors suggested that,for industrial operations,wood color could be controlled by adjusting treating temperature,while slight color change could be affected by adjusting treating time.

        摘要：The authors made an investigation on dust and volatile organic compounds（VOCs）produced during wood furniture manufacturing.The results showed that the total dust concentration during mechanical processing was lower than that produced during semi-mechanical and handwork processing.Sanding resulted in a certain amount of free silica in addition to wood dust.There were heavy metals such as Lead（Pb）and Cadmium（Cd）in the dust from putty sanding and painting.Total volatile organic compound emissions depended on painting method and procedures.It was suggested that occupational exposure limits of dust be established for wood furniture manufacturing and spray chamber,ventilation installation and gas-cleaning facilities should be used to effectively cut down TVOCs concentrations.
