Pulp slurry suspension is a complex multi-component system, it contents filler, starch and some other special chemical AIDS in addition to pulp fiber and fibril.
Adopting bicomponent retention system greatly improved filler retention rates, thereby increasing the amount of filler to increase the content of filler in paper, lower pulp consumption and costs.
通过改用助留系统，大大提高填料留着率，从而提高纸张中填料的含量，降低浆耗和成本。

The study showed that this kind of cationic starch has more positive charges and has good effects on the fibers. It has significant effect on filler retention and drainage in deinked pulp.
