摘要
The ONP neutral deinking performances of fatty alcohol polyoxyethylene ether with different EO value were investigated in this paper. 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.
