        摘要：Four inorganic fire retardants,melamine cyanurate（MCA）,melamine phosphate（MP）,zinc borate（ZB）and phosphate sulfate salt（PSS）,were selected to investigate the effects of inorganic fire retardants on curing reaction of urea formaldehyde（UF）resin by differential scanning calorimetry（DSC）.We found that resin gel time was extended by adding ZB.However,pH resin value decreased by adding MCA,PSS and MP resulting in shortened gel time and lower resin curing start temperature.Medium density fiberboards（MDF）were manufactured with UF resin using the above-mentioned fire retardants.We found that the fire retardant treated MDF samples had lower internal bond strength（IB）than control MDF samples.

        摘要：Wood/jute/polypropylene（PP）fiber panels are used forautomotive interior trims when fiber mat is hot pressed into composite panels.Prior to pressing,the fiber mats were impregnated with water-soluble ammonium polyphosphate fire retardant,and then the fire retardant effectiveness for the panels was tested.The test result indicated that water absorption and fire retardancy were all improved but the modulus of rupture（MOR）of the panels was reduced slightly.Combustion speed was reduced to 0mm/min while char yield and limiting oxygen index（LOI）were increased.When weight gain rate of the panels reached 43.9%,the sample’s LOI was 27.84%,which met the requirement of the National Standard GB 50222-1995（2001）for the B2 grade.

        摘要：This paper analyzed wood thermal modification technologies in Europe.Atmospheric steam treating technology is mainly used and typically represented by Thermowood technology with features such as relatively simple process,low investment cost,diverse equipment supply and high unit output.Pressurized steam process has the advantage of shorter treating time and lower treating temperature.Vacuum process can guarantee uniform product quality with easy equipment maintenance.For the combined process,small-volume equipment can achieve high production capacity by optimal equipment combination and process design.

        摘要：Bamboo scrimber samples made of Neosinocalamus affinis were treated separately with seven kinds of antimold chemicals.Antimold performance of the samples,with and without washing,was tested.Testing results showed that the antimold performance of all seven samples was significantly weakened by washing.The samples with high antimold chemical retention had better performance than that with low retention.Solid antimold chemicals,such as zinc borate（ZB）,boric acid and borax（SBX）,showed better antimold performance and were suitable to treat bamboo scrimber for outdoor uses.

        摘要：对多层实木复合地板的柞木面板进行热处理,分析了热处理工艺对面板颜色、变形及耐湿耐热尺寸稳定性等的影响。结果表明:随着热处理温度升高和时间延长,面板耐湿耐热尺寸稳定性均提高,但差异不明显;颜色逐渐变深,均产生翘曲和扭曲变形;长度和宽度方向的收缩率增加,旋切板为甚;对于2 mm厚的柞木面板,温度160180℃,时间1.02.0h是较为适宜的热处理工艺。
