1、Error!Notextofspecifiedstyleindocument.摘要以人工林定向培育材杨木、落叶松为原料,采用干法工艺、连续式平压压机生产幅面规格为1220×2440mm,厚度为12mm中密度纤维板。削片之前,将弯曲度过大的小径木截断可以保证连续化生产,也可以防止木材损坏削片机的进料机构。在原料制备阶段采用盘式削片机,削片大小合格、均匀,质量较好。由于原料的特点,在木片蒸煮前加了木片的水洗系统,可以清除原料中所含有的泥沙,调节木片含水率。纤维热磨阶段,采用低温热磨,纤维质量相对较好。纤维气流干燥阶段,增加了自动防火灭火系统控制操作装置,
2、确保生产安全运行。使用机械-气流真空成型机,纤维铺装均匀、质量好。连续平压压机与多层周期式热压技术相比,连续压机有产品质量好、原料损耗低、生产连续化,成品板幅面规格多等优点,特别是薄板生产时产品可以不砂光,原材料损耗小、利用率高。综合效益佳。关键词:干法;纤维板;连续平压压机;工艺设计29--Error!Notextofspecifiedstyleindocument.AbstractTakepoplarandlarchwhichareplantedforestdirectedbreedingmaterialasarawmaterial,usesth
