Abstract
強度低下と、投入エネルギーが少なく、高い寸法安定性と耐朽性を持った熱処理木材の製造方法を提供する。
【解決手段】
超臨界二酸化炭素中で木材を加圧加熱することを特徴とする加熱木材の製造方法。
【選択図】 なし
Description
(1) 超臨界二酸化炭素中で木材を加圧加熱することを特徴とする熱処理木材の製造方法。
(2) 前記加圧圧力が7.4〜30MPaであることを特徴とする(1)に記載の熱処理木材の製造方法。
(3) 前記加熱温度が150〜250℃であることを特徴とする(1)または(2)記載の熱処理木材の製造方法。
(4) 木材を収容する耐圧容器と、耐圧容器に備えられた大気圧解放用バルブと、二酸化炭素を充填した充填容器と、該充填容器から耐圧容器に流体を加圧注入する加圧ポンプと、耐圧容器内を加熱する加熱器を備えたことを特徴とする熱処理木材の製造装置。
以上の結果から、従来の乾式法と比べ、本発明による処理法ではMOEおよびMORの低下が抑えられることが示された。なお、この実施例では本発明による処理法と従来法を同じ処理条件で比較しているが、本発明を用いることで処理時間の短縮が期待されるため、強度低下がさらに抑えられる可能性がある。
