活性碳纤维及其制品的制备

MANUFACTURING TECHNOLOGY OF ACTIVATED CARBON FIBER AND ITS PRODUCTS

本文为了探求聚丙烯腈基活性碳纤维及其制品的生产工艺 ,分别采用聚丙烯腈纤维(PANF)与粘胶纤维 (VF)混纺制毡 ,再经预氧化 ,以及采用聚丙烯腈预氧化纤维 (OPANF)纯纺两种方法制备预氧化纤维毡 (非织造布 ) ,然后对预氧化纤维毡采用水蒸气活化法活化制得聚丙烯腈基活性碳纤维 (PAN ACF)。

In the paper,in order to find the best manufacturing technology of polyacrylonitrile based activated carbon fiber (PAN ACF)and its products that two methods were used to produce proxidation polyacrylonitrile fiber (OPANF) no wovens.The method I is to blend polyacrylonitrile fiber(PANF) with viscose fiber(VF) and preoxidate it to produce OPANF no wovens.The mehtod Ⅱ is to spin OPANF directly to produce OPANF no-wovens.OPANF no wovens was activated with water vapour to manufacture PAN ACF.\;
