以低卡伯值硫酸盐麦草浆为原料，经过酸预处理、螫合预处理后，浆料进行H2O2强化臭氧漂白工艺比较。
The kraft low-kappa number wheat straw pulp was bleached by ozone with the addition of H2O2 after acid pretreatment and chelating pretreatment.
然后经过臭氧-过氧化氢漂白，结果表明：卡伯值越高，脱木质素选择性越差，白度上升值越低。
Then ozonic-hydrogen peroxide bleaching were carried out and the results show that the higher of Kappa number, the poor of the delignification selectivity and the lower of brightness rising.
比较高卡伯值制浆和中、低卡伯值制浆对后续氧脱木素和ECF漂白的影响。
Kraft pulping, oxygen delignification, and ECF bleaching were regarded as a whole system, and the technologies were optimized systematically.
