Abstract:The retention and drainage effects of nanosized TiO2 colloids and modified starch reinforcer double-element systems were studied by using DDJ. The effects of the double-element systems on the paper strengthening and the removal and control of DCS were also evaluated by making handsheets with whitewater recycling. The results showed that when the dosage of nanosized TiO2 was about 0.4%, the first pass retention increased by 5%~12% on an average. Compared with cationic starch (CS), amphoteric starch (AmS) and nanosized TiO2 had better synergy. It was found that nanosized TiO2 had positive influence on amphoteric starch reinforcer and nanosized TiO2-AmS system had significant effect on the removing of DCS.
