| 摘 要： | 研究了棉秆浆无元素氯短程序DQP漂白各段工艺条件。研究结果显示，D段在用氯量1％时能获得较好的漂白效果，白度可以达到75％ISO以上；D段在其它条件不变时，硫酸用量在2．5％以内用量越多漂白效果越好，但是纤维降解增加，硫酸用量不宜超过1．5％；P段中的NaOH用量为1％时漂白效果较好，P段H2O2用量超过1.5％以上白度几乎不再提高，而纸浆粘度和尘埃度随着H2O2用量增加继续下降。 |

| Abstract: | Technological conditions of each stage during DQP bleaching of cotton stalk soda-AQ pulp were studied in this paper.The results indicated that the DQP bleached pulp could reach 75% ISO brightess as 1.0% ClO_2 was used in D stage.At the same other conditions,with the increase of H_2SO_4 dosage within 2.5% in D stage,the brightness of DQP bleached pulp increased,but the viscosity of the pulp decreased.The suitable H_2SO_4 dosage in D stage was 1.5%.In P stage,1% of NaOH charge and 1.5% of H_2O_2 dosage resulted in better bleaching effect.With the increase of H_2O_2 dosage,both pulp viscosity and dirt count number reduced. |
