| 摘 要： | Microparticle retention system, developed lately, mainly consists of cationic polymers and anionic inorganic substances, such as Hydrocol system consisting of cationic polyacrylamide/modified bentonite and Compozil system2] with cationic starch/anionic silica sol. The principle of electrostatic interaction has been adopted for these systems. Whereas if there are plentiful anionic trashes in systems, their efficiency will not embody primely. Although anionic trash catcher (ATC) could be adde…

| Abstract: | The retention and drainage performances of microparticle retention system were studied in this paper, through measuring the improvement of beaten degree and retention ratio of slurry. The effects the retention system on paper sheet were discussed by measuring physical properties of paper. Compared with the influence of Hydrocol system (CPAM/bentonite) on the aspects of retention aid and drainage properties as well as increased product cost per ton paper, the developed nonionic system has some superiority and better practicability. |
