摘要

进行了麦草浆的水浴加热漂白和微波辐射漂白对比实验，考察了微波辐射H,2,O,2,漂白过程中微波辐射功率、处理时间、H,2,O,2,及NaOH用量对漂白纸浆性能的影响，采用正交试验的方法对实验条件进行了优化，并用纤维分析法对纸浆纤维形态进行了研究。微波辐射H,2,O,2,漂白纸浆的最佳工艺条件是：微波辐射功率240 W、辐射时间2.5 min、H,2,O,2,用量5%、NaOH用量4.5%，在此条件下纸浆白度可达59%ISO左右。纤维分析测定结果发现微波辐射漂白前后纸浆纤维形态基本没有发生变化。结果表明，微波辐射替代水浴加热应用于H,2,O,2,纸浆漂白是一种切实可行的方法。

Abstract

Hydrogen peroxide bleaching processes of wheat straw pulp by microwave radiation in water bath were investigated. The effects of microwave power, process time, H,2,O,2, dosage and NaOH dosage on the quality of the bleached pulp were investigated. And the experiment conditions were optimized by using the method of orthogonal test. The form of the pulp fiber was measured by fiber analysis. The best process conditions for hydrogen peroxide bleaching process of paper pulp by microwave radiation could be made in condition such as microwave power was 240 W, process time was 2.5 min, H,2,O,2, dosage was 5% and NaOH dosage was 4.5%. In optimal process, the whiteness of paper pulp could reach about 59%ISO. The fiber analysis indicated that the form of the pulp fiber did not vary from that before reaction. The results showed that microwave radiation in stead of water bath was good for H,2,O,2, bleaching process of paper pulp.
