槟榔壳原料及制浆性能研究

摘要

The chemical composition and pulping properties of areca-nut,the fiber morphology and bleaching of areca-nut pulp and the physical properties of the paper sheets were analyzed and studied in order to provided technical data for the rational use of areca-nut as fiber resource.The results showed that areca-nut contained higher acid insoluble lignin(30.05％),the fiber length of areca-nut pulp was shorter.The difficulty of bleaching was due to high levels of acid insoluble lignin.The physical properties of the paper made of the areca-nut pulp were higher than the Grade A corrugating medium of national standard.Areca-nut was not suitable for producing bleached pulp and it could be used as part of the furnish for producing packaging paper such as corrugating medium.%分析了槟榔壳原料的化学组成、制浆性能、槟榔壳纸浆的纤维形态、漂白及其纸张的物理性能,为槟榔壳纤维资源的合理利用提供技术数据.结果表明,槟榔壳原料木素含量较高(Klason 木素含量为30.05％)、纸浆纤维较短(数均长度0.38～0.43 mm,长均长度0.52 ～0.58 mm,质均长度0.65～0.71 mm)、卡伯值较高(33.8～73.3)、CI02漂白浆白度为21.7％ ～31.4％,白度提高不大,因此槟榔壳原料不适合生产漂白浆.而槟榔壳纸浆所抄纸张的抗张指数、撕裂指数、耐破指数、环压指数均高于用废纸浆所生产的A级瓦楞原纸的物理性能,由此认为槟榔壳纸浆适合生产瓦楞原纸等包装用纸.
