摘要:
为提高二醋酸纤维对烟气的吸附性能,采用二醋酸纤维素(CA)/纳米碳酸钙(CaCO3)为溶质,二氯甲烷(DCM)/丙酮为复配溶剂,利用高挥发性溶剂制备了CA/CaCO3复合纤维,再经稀醋酸溶液酸洗移除CaCO3获得多孔二醋酸纤维。文章在对纤维形貌和比表面积进行表征的基础上,对多孔二醋酸纤维及其在滤嘴中的相对位置对烟气中醛类物质吸附效果进行了测试分析。结果表明:碳酸钙的掺杂有利于纤维多孔形貌的形成,随着碳酸钙掺增至6%,纤维比表面积可扩大3倍左右,可明显提高滤嘴的吸附效果;并且当多孔纤维过滤段与无孔纤维滤段呈“三明治”形式构成时,滤嘴吸附过滤效果最佳。
Abstract:
In order to improve the adsorption performance of diacetate fiber on smoke , CA/CaCO 3 composite fibers were prepared by using cellulose acetate (CA)/ nano calcium carbonate (CaCO3) as the solute, taking dichloromethane (DCM)/ acetone as the compound solvent and utilizing a volatile solvent. Then, (CaCO3) was removed by acid pickling with d ilute acetic acid solution to obtain porous diacetate fiber. Based on representing the fiber morphology and specific surface area, the adsorption effect of porous diacetate fiber and its relative position in the filter tip on aldehydes materials in smoke was tested and analyzed. The results showed that, f calcium carbonate doping was beneficial to the formation of porous morphology of the fiber. As calcium carbonate doping increased to 6%, specific surface area if fibers could be enlarged by about 3 times, and the adsorption effect of filter tip could improve significantly. When porous fiber filtration section and imporous fiber filtration section presented “sandwich” form composition, the filter tip had the best adsorption and filtration effect.
