摘　　要：以废弃杨木水泥模板纤维为原料制造纤维板,实现杨木的循环利用。对水泥模板以及分离好的纤维性能进行测试分析,并分别以废弃杨木水泥模板纤维、新鲜杨木纤维为原料制造不同密度的纤维板,讨论原料特性和施胶量对板材性能的影响。研究结果表明:废弃杨木水泥模板表面碳元素含量高于杨木单板表面,而水泥模板表面的氧元素含量较低;废弃杨木水泥模板纤维的堆积密度与新鲜杨木纤维基本相同;当用水泥模板制得的纤维板密度达到0.75 g·cm-3时,板材的力学性能和吸水厚度膨胀率(TS)值均优于其他密度的板材,当施胶量大于等于12.0%时,板材的弹性模量(MOE),静曲强度(MOR),内结合强度(IB)性能均能满足国家标准值的要求。因此,废弃杨木水泥模板完全可以替代普通杨木制造纤维板。To illustrate comprehensive utilization of limited resources,recycled poplar cement formwork fiber was manufactured into fiberboard.In this study basic properties of fibers and fiberboard were characterized.Then,the effect of density and glue consumption on the mechanical and physical properties of the fiberboard was studied followed by a comparative analysis with ordinary poplar fiberboard via a single factor duplicate test.Results showed that the carbon （C） content of the recycled poplar cement formwork fiberboard was higher than that of poplar veneer by about 5.7%; whereas the oxygen （O） content was lower about 3.3%.Bulk density of recycled cement formwork fibers was equal to that of poplar fibers.When board density was 0.75 g·cm^-3 and glue consumption was 12.0%,both mechanical properties and thickness swelling （TS） were maximized and were greater than the general fiberboard.Thus,it was possible to manufacture qualified fiberboard to meet Chinese standards using recycled poplar cement formwork instead of poplar.
