03/2008 | Radiochimica Acta, Oldenbourg WissenschaftsverlagEffects of thermomechanical refining conditions on the morphology and thermal properties of wheat straw fibre
Wheat straw fibre is prepared by a thermomechanical (TM) refining system. This study investigated the effects of refining steam pressure (4, 6, 8 and 10 bar) and refiner speed (2500 and 3000 rpm) on the morphology and thermal properties of the resulting fibres...
