摘　　要：对麦草浆、杨木浆和混合浆进行HP短序漂白。结果表明,kappa值较低的麦草浆、杨木浆和草木混合浆在HP漂白中表现出较好的可漂性,经4%～5%的次氯酸盐用量和3%～4%H2O2用量可漂至78%ISO以上,有些可达80%ISO以上,且漂后浆物理性能较好。杨木浆HP漂白现场调试成功的结果表明HP漂白可取代传统的CEH漂白。The study on HP short sequence bleaching process of wheat straw pulp, aspen pulp and mixed pulp was carried out. The results showed that the lower kappa number wheat straw pulp, aspen pulp and grass/wood mixed pulp were easy to bleach in HP bleaching sequence, at hypochlorite charge 4%～5% and hydrogen peroxide charge 3%～4% in HP bleaching sequence, they could bleach to 78%ISO brightness, some could bleach to 80%ISO, the physical property of the bleached pulp was well. The results of successfully debugging the scene of HP sequence bleaching aspen pulp showed that HP bleaching sequence could be used as the substitute for the conventional CEH process.
