The causes about the difficulties in deinking of water-based ink printing waste paper arising from the composition of water-based ink and the conditions of redeposition were described,and the difficuties about the treatment of deinking effluent also introduced.
介绍了水基油墨的组分和产生再沉积的条件等造成水基油墨印刷纸脱墨困难的原因,同时介绍了脱墨废水处理的困难。
Nanon disperse blue 2BLN was prepared from traditional filter-cake by ball milling,reprecipitation and pressure homogenization.
普通分散蓝2BLN染料滤饼和分散剂经机械球磨得到染料分散液,滴加到快速搅拌的分散剂水溶液中进行再沉淀,得到的染料粗品在100 MPa下进行高压均质得到纳米级分散蓝2BLN液体染料,并完成了1 t/批的中试工业化实验研究。
