| titleOfInvention | Device for the production of paper, cardboard and cardboard |
| abstract | Device comprising a cationic polymer of a microparticle system for the production of paper, cardboard and cardboard, wherein - the paper stock is sheared, - The microparticle system of a cationic polymer and a finely divided inorganic component is added to the paper stock after the last shear stage before the headbox, and - the paper stock is dewatered with the formation of sheets and drying of the sheets, characterized in that cationic polyacrylamides, polymers containing vinylamine units and / or polydiallyldimethylammonium chloride with an average molecular weight Mw of at least 500,000 daltons and a charge density of at most 4.0 meq./g each are used as the cationic polymers of the microparticle system, this being used as a retention agent The microparticle system used is free of polymers with a charge density of more than 4 meq./g. |
