Low oxygen content prevents the wood from burning at these high temperatures. Several different technologies are introduced using different media including nitrogen gas, steam and hot oil. ==Modification processes== The first technological approach of thermal modification processes of wood is the paper of Burmester.〔Burmester, A. (1973): Einfluß einer Wärme-Druck Behandlung halbtrockenen Holzes auf seine Formbeständigkeit. Holz als Roh- und Werkstoff 31, pp. 237–243〕 There are 5 different thermal modification processes : Thermowood (or Premium wood) in Finland, Retification process (Retiwood, New Option Wood) and Le -Bois Perdure in France, Plato process in Netherlands, Oil-heat treatment in Germany (OHT-Process) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thermally modified wood」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
