1、Error!Notextofspecifiedstyleindocument.摘要以人工林定向培育材楊木、落葉松為原料,采用干法工藝、連續(xù)式平壓壓機生產幅面規(guī)格為1220×2440mm,厚度為12mm中密度纖維板。削片之前,將彎曲度過大的小徑木截斷可以保證連續(xù)化生產,也可以防止木材損壞削片機的進料機構。在原料制備階段采用盤式削片機,削片大小合格、均勻,質量較好。由于原料的特點,在木片蒸煮前加了木片的水洗系統(tǒng),可以清除原料中所含有的泥沙,調節(jié)木片含水率。纖維熱磨階段,采用低溫熱磨,纖維質量相對較好。纖維氣流干燥階段,增加了自動防火滅火系統(tǒng)控制操作裝置,
2、確保生產安全運行。使用機械-氣流真空成型機,纖維鋪裝均勻、質量好。連續(xù)平壓壓機與多層周期式熱壓技術相比,連續(xù)壓機有產品質量好、原料損耗低、生產連續(xù)化,成品板幅面規(guī)格多等優(yōu)點,特別是薄板生產時產品可以不砂光,原材料損耗小、利用率高。綜合效益佳。關鍵詞:干法;纖維板;連續(xù)平壓壓機;工藝設計29--Error!Notextofspecifiedstyleindocument.AbstractTakepoplarandlarchwhichareplantedforestdirectedbreedingmaterialasarawmaterial,usesth
