摘　　要：本实验研究的目的是利用微波辐射加速麦草浆漂白和提高白度,减少漂白剂对环境的污染及对纸浆中纤维素的损伤,有效提高纸浆的质量.经实验表明,微波辐射替代水浴加热应用于NaClO纸浆漂白是一种切实可行的方法.其最佳工艺条件是微波辐射功率240W,辐射时间2.5min,NaClO用量4.2%,NaOH用量1%,在此条件下纸浆白度可达61%ISO以上.In this paper, NaClO bleaching process of wheat straw pulp by microwave radiation method was conducted, in order to accelerate the bleaching process, increase the brightness of the pulp, reduce the environmental pollution and decrease the damnification to the fiber in the pulp. It was proved that microwave radiation in stead of water bath is good for NaCIO bleaching process of paper pulp. The results showed that the best process conditions could be： microwave power was 240 W, process time was 2.5 min, NaCIO dosage was 4.2%, NaOH dosage was 1%. In optimal process, the brightness of paper pulp could reach more than 61%ISO.
