| 摘 要： | 对旧报纸漆酶脱墨工艺进行了研究.得出了最佳工艺条件:漆酶用量10 LAMU/g,介体(Violuric Acid)用量0.5%,碎浆时间30min,保温时间15 min,通氧气,温度55～60℃.在此条件下进行脱墨,所得脱墨浆白度与对照浆相比有所降低,但可漂性提高.漂白后浆白度达到52.4%ISO,与对照浆相比提高4.2%ISO.此时裂断长为2.16 km,撕裂指数为7.01mN·m2/g,与对照浆相比分别提高了20%和13%. |

| Abstract: | Deinking technology of ONP with Laccase Mediator System (LMS) was studied. Results showed that the optimum pulping conditions were: laccase charge 10 LAMU/g, mediator (violuric acid) charge 0.5%, time of pulping 30 min, and the retention time of the pulp at the optimum temperature 15 min. The brightness of the LMS deinked pulp was lower than the control pulp. However, the brightness of the LMS deinked pulp bleached with H 2O 2 was 52.4%ISO which was 4.2 points higher than that of the control pulp. The breaking length and the tearing index of the deinked pulps were 20% and 13% higher respectively than those of control pulp. |
