| 摘 要： | 研究了亚硫酸钠对废新闻纸的脱墨以及脱墨浆漂白效果的影响。结果表明,与不加亚钠的对照浆相比,亚钠的加入可以防止脱墨浆的返黄,提高脱墨浆的白度,降低脱墨浆的残余油墨浓度。亚钠脱墨浆经连二亚硫酸钠漂白后可以达到与传统碱法化学脱墨浆相近的白度。 |

| Abstract: | The influence of sodium sulfite on the deinking and on the bleaching effect of deinked pulp was investigated. The results show that sodium sulfite can prevent the brightness reversion of deinked pulp, improve the brightness of deinked pulp and decrease remnant ink density in deinked pulp compared with a comparison sample. After being bleached by sodium dithionite, the brightness was similar to that of pulp obtained from the conventional alkali deinking method. |
| Keywords: | sodium sulfite deinking old newsprint |
