Meanwhile, the synergistic effects of different non-ionic surfactants, the co-operation of non-ionic surfactants with anionic surfactants,and the effects of different salts added into the above two systems on deinkability were also studied. The results showed the deinking performance of A7 was good. But the synergistic effect of A7 and A4 was better. In addition, the accession of salt W2 could improve the deinking efficiency, and the brightness of the deinked pulp was 1.0%ISO higher than that of A7 and A4.展开更多

Pluronic block copolyether did not have good deinking performances, polyoxyethylene alkyl ether, polyoxyethylene carboxylate and polyoxyethyleneoxypropylene alkyl ether could be used as one component of flotation deinking agents for ONP.展开更多

We mainly studied the relation between deinking efficiency of different recovery pulps and their colloid-chemical behavior such as Zeta potential and surface tension. Technical conditions that affect the deinking pulp’s colloid chemical behavior are also analyzed here.展开更多
