摘要: Abstract The present work aims at assessing the main characteristics of lignocellulosic micro/nanofibers (LCMNF) from bleached thermomechanical pulp (BTMP) spruce while glimpsing suitability cationic demand (CD) as effective monitoring parameter fibrillation process. For this, BTMP was mechanically refined different times in a Valley beater, aiming determining required refining time and fiber length to be later fibrillated high-pressure homogenizer. It found that 150 min treatment is avoid clogging pressure chambers treated gradually passed through homogenizer, leading four LCMNF with degree. were determined, well effect homogenization may generate onto structure. observed CD robust monitor process, it good indicator characteristics. In addition, WRV not extent for LCMNF, lignin content varies intensity. Finally, limitations perspectives on this regard are provided reader.
