摘要
脱墨浆的过氧化物漂白中,释放出大量的阴离子杂质,通过阴离子杂质对纸浆性能的影响研究,结果表明,溶出的大量阴离子杂质不但降低了纸浆白度与强度性能,阳离子助剂也有影响。采用果胶酶处理废新闻纸脱墨浆,纸浆阳离子需要量降低、滤水性能得到改善,阳离子助剂CPAM对纸浆的助滤作用明显提高。酶处理对成纸的白度与强度性能没有负面影响。
The Dissolved substances（DS） effect on the pulp properties of experiments was studied in this paper. It was found that the process of bleaching pulp released a large number of anionic trashes not only reduce the brightness and strength properties. And the CPAM drainage ability was also disturbed. With pectinase treatment old newsprint deinked pulp, cationic demand of pulp was decreased. Pectinase treatment improved the CPAM drainage ability significantly without negative effect on the strength properties.
