與前所述，不加粘結劑的成型工藝，根據對物料加溫形式不同，可劃分為常溫成型（不加溫）、熱壓成型（擠壓過程中加溫）、預熱成型（擠壓之前加溫）和成型碳化（擠壓後熱解碳化）4種主要形式。其中，常溫成型工藝必須對纖維類原料浸泡數日水解處理後，才能改善其壓縮成型特性明顯，使纖維變得柔軟、shirunzhouliebingbufenjiangjie，yiyuyasuochengxing。yinci，gaigongyishengchanzhouqichang，xuyaomianjidadeshengchanchangdihexiangyingdesheshi，chanpinweidimidudeyasuochengxingranliaokuai，gubenwenbucaiyonggaigongyi，futongxinnengyuanshengchanxiaoshoujieganjieganyakuaiji、秸稈顆粒機等生物質成型機械設備，同時我們也大量銷售楊木木屑生物質顆粒燃料。
