高强度植物基活性炭纤维制备研究
摘要
文中以丝瓜络纤维为原料、水溶性酚醛树脂为浸渍剂,通过浸渍预处理、预氧化、高温炭化活化等工艺制备出高强性能植物基活性炭纤维(HP-ACF),考察了升温速率、预氧化温度、预氧化时间、活化温度、活化时间对HP-ACF的抗压强度的影响。采用碘吸附值、N2吸附-脱附等温曲线对HP-ACF表面孔结构进行表征,抗压强度值对HP-ACF抗压性能进行表征。试验结果表明:(1)制备产品HP-ACF抗压强度为0.246MPa;(2)HP-ACF微孔丰富,孔径为1.82nm,孔容为0.1922 cm3·g-1,比表面积为422.47m2·g-1,碘吸附值为341.08mg·g-1;(3)HP-ACF在环保领域有良好的应用前景。
