        摘要：In order to simplify the modification process and reduce the cost of wood acetylation,the authors developed a wood acetylation technology using pure acetic anhydride without any catalysts.Effects of reaction temperature and time on weight percentage gain（WPG）of the acetylated Populus ussuriensis wood were evaluated and physical and mechanical properties were tested.Testing results showed that the WPG of the acetylated wood improved with increased reaction temperature and time.Density and anti-swelling efficiency（ASE）of the acetylated wood improved with increased WPG.Effects of the acetylation on modulus of rupture（MOR）and modulus of elasticity（MOE）in static bending were insignificant.Fourier transform infrared（FTIR）analysis indicated that hydrophilic hydroxyls of chemical components of the acetylated wood were replaced by acetyls and hydrophobic esters formed after acetylation,which explained why dimensional stability of the treated wood was improved.

        摘要：An isocyanate resin and an FRA retardant developed by the authors were used to manufacture fire-retardant low density fiberboards at 0.40 g/cm3.Four technological factors,including resin consumption, hot-pressing temperature, pressing time and fire-retardant consumption were investigated and the performance of the fiberboards was evaluated.The results showed that the FRA retardant consumption could improve the fire-proof property of the fiberboards.The performance of the fiberboards made under optimal conditions could meet the specifications of industrial standard LY/T 1718-2007 for low density fiberboard.

        摘要：Green eucalyptus from plantation forests was modified by the sol-gel method.Microstructure and silicon dioxide（SiO2）distribution of the samples were evaluated with scanning electron microscopy（SEM）/ energy dispersive X-ray analyzer（EDAX）and Fourier transform infrared（FTIR）and then were tested for physical and chemical properties.The results showed that soaking time had a very important effect on content and distribution of SiO2.Weight percentage gain（WPG）and air dry density of the samples could reach 45% and 0.6 g/cm3,respectively.Bending strength,hardness and light aging resistance of the modified samples were also improved.

        摘要：In order to fully evaluate combustion properties,five kinds of woody flooring products were tested with a flooring material burning apparatus in accordance with the Chinese National Standard GB/T 11785-2005 and a cone calorimeter.The results showed that all the samples could meet requirements of the National Standard when flame retardant materials were tested with the burning apparatus.However,results of samples tested with the cone calorimeter showed the following differences:a solid wood flooring product coated with fire-retardant lacquer had good fire retardancy while two engineered flooring products without fire retardant treatment were easily ignited and had a higher heat release rate.A laminate flooring product and a flooring product made from stone,wood and PVC,without a fire retardant treatment,showed excellent fire retardancy but the latter released a large amount of smoke during testing.
