Hydrophilic dispersion polymers of diallyldimethyl ammonium chloride and acrylamide for the clarification of deinking process waters |
摘要 |
The invention comprises a method for clarifying ink-laden water obtained fro m the recycling of paper stocks by treating said water with a hydrohilic dispersion polymer. The hydrophilic dispersion polymer of the invention is a copolymer of a diallyl N,N-disubstituted ammonium halide cationic monomer an d (meth)acrylamide (AcAm). Following dosing with the polymer, a floc is formed . The floc contains ink and impurities which are removed from the water proces s stream by means of solid liquid separation; the solid liquid separation comprising a dissolved air flotation method. A preferred copolymer is formed from DADMAC and AcAm. |
