摘　　要：介绍了ONP/OMG碎解时只加缓冲剂和亚硫酸钠以增强脱墨效果的研究,结果指出油墨剥离程度提高了,油墨碎片化程度减少了,纸浆深色化程度降低了和纸浆漂白效果增加了。这些都还与缓冲剂调节pH大小和控制碎解时间长短有着密切的关系。The buffer solution and sodium sulfite were only added during ONP/OMG repulping to increase the deinking efficiency and the effect was introduced in this paper. The results show that the ink detachment was increased, the ink fragmentation was decreased and the pulp brightness was increased. All these are intimately related to the pH control by buffer solution and repulping time control.
