Effects of Different Pretreatment on the Dispersibility of Bamboo Pulp Fibers Suspensions
摘要
Abstract
Industrial production efficiency of nanocellulose by mechanical homogenization was directly affected by dispersibility of pulp sus-pensions.The bamboo pulp was pretreated by TEMPO,enzymatic hydrolysis and refining to study dispersibility of the pulp suspensions.Physical morphology and surface charges of the pretreated pulp fibers were analyzed to explain the differences of dispersibility.Multiple light scattering results showed that TEMPO oxidized pulp fibers and refined pulp fibers had good dispersivity,while the enzymatic pulp fibers had bad dispersivity.Fibrillation on the refined pulp fibers was observed by scanning electron microscope(SEM).The TEMPO oxidized pulp fi-bers had high carboxylate contents and high absolute value of Zeta potential.The dispersibility of the fibers could be improved by disper-sants,and the best dispersibility of enzymatic hydrolysis fibers was obtained with 0.5％CMC dispersant.关键词
