研究了利用微波技术辅助NaClO对杨木浆进行单段漂白工艺的影响。并通过正交实验确定最佳漂白工艺为:微波辐射时间4.5min,微波辐射功率150W,NaClO用量4%。此时白度可以达到65.73%ISO,残氯低至0.0843g·L-1,得率97.36%。
The effect of using microwave technology to assist single phase bleaching of poplar wood pulp with NaClO was studied. The optimal bleaching process was determined by orthogonal experiment: microwave irradiation time 4.5min, microwave irradiation power 150W, NaClO dosage 4%. At this point, the whiteness can reach 65.73% ISO, residual chlorine as low as 0.0843g · L-1, yield 97.36%.
