进口彩印杂志废纸浆臭氧漂白工艺的研究

Ozone Bleaching Process of Heavily Printed Magazine Waste Paper

对脱墨废纸浆的臭氧漂白工艺过程进行了研究， 结果表明： 在适当的工艺条件下采用臭氧漂白技术，可以将经常规脱墨技术处理的进口彩印杂志废纸浆进一步提高白度至８４－５％ ＳＢＤ， 该浆具有较好的物理强度性能。

Ozone bleaching is one of the most promising technologies striving to make chlorine free bleaching of kraft pulp.The bleaching process using ozone as main chemicals to treat heavily printed magazine waste paper is studied in the report, and some technological parameters affecting bleaching process have been discussed.Results presented in this paper show that deinked fibers can be treated with ozone followed by an alkline peroxied extraction (ZEp), and a resultant bleached pulp with brightness of 84.5%SBD can be produced.
