Method for improving drainage of paperboard |
| abstract |
(57) [Summary] [Purpose] To provide an optimal drug formulation for a method of efficiently dehydrating a stock material to enhance productivity by adding it to a papermaking process of paperboard in a papermaking factory to enhance productivity. A drainage improving agent and colloidal comprising an acrylic cationic water-soluble copolymer containing 5 mol% or more of acryloyloxyethyldimethylbenzylammonium salt structural unit, acryloyloxyethyltrimethylammonium salt structural unit and acrylamide structural unit, respectively. The purpose can be achieved by using silica together with the addition of silica in the papermaking process. When the acrylic cationic water-soluble copolymer is added before the sentry screen and the colloidal silica is added after the sentry screen, the productivity improving effect is particularly remarkable. |
