FAS代替保险粉对废纸脱墨浆补充漂白的研究

Study on the Supplemental Bleaching of Deinked Pulp by FAS Instead of Sodium Hydrosulfite

FAS是一种优良的纸浆漂白剂。该文采用FAS代替保险粉对废纸脱墨浆补充漂白进行了实验研究。结果表明，采用FAS代替保险粉对H2O2预漂白处理后的混合废纸脱墨浆进行漂白是完全可行的，可以在同成本的情况下达到原来的漂白效果，并且可以减轻废水对环境的污染。

FAS is an excellent pulp bleaching agent, we carried out an experimental study on bleaching of deinked pulp by FAS instead of the sodium hydrosulfite. The results showed that feasible to replace sodium hydrosulfite with FAS, the original bleaching effect can be achieved at can reduce the pollution of waste water as well. the supplemental it was completely the same cost and can reduce the pollution of waste water as well.
