摘　　要：对Soda-AQ麦草浆少污染OHP漂白进行了研究。实验结果表明,使用少污染OHP三段漂白,氧漂时NaOH用量3%,未漂浆的脱木素率达44.03%,随后的次氯酸盐漂白只需3%有效氯用量即可将浆料漂至75.05%ISO,再用2%H2O2进行漂白,纸浆最终白度可达80.55%ISO,纸浆黏度为464.9mL/g。The study on OHP bleaching process of soda-AQ wheat straw pulp was carried out.The results show that using OHP three-stage bleaching,the lignin removal rate of the unbleached pulp can reach 44.03% after the oxygen delignification,then,the pulp can be bleached to a brightness of 75.05%ISO by merely adding 3% active chlorine in the subsequent stage of hypochlorite bleaching.And then after the hydrogen peroxide bleaching(at H2O2 charge 2%),the pulp brightness is 80.55%ISO and the viscosity of the pulp is 464.9...
