| Abstract:Cationic spherical polyelectrolyte brush has become new area of research as paper retention and drainage aids because of its structure characteristics.In this paper, the spherical polyelectrolyte brushes (CS-PDMC) with carbon spheres (CS) as core and methyl methacrylate three methyl ammonium chloride (DMC) as shell were prepared. The effects of different CS-PDMC dosageson the retention rates of two kinds of fillers (GCC, kaolin) and on the drainage of the furnishescontaining two kinds of fillers (GCC, kaolin) were studied. When 15% GCC(on the oven-dried pulp) and 0.8% CS-PDMC were added to the pulp, the retention rate of the filler was the highest for 79.3%; When 15% kaolin and 1.0% CS-PDMC were added to the pulp, the retention rate of the filler was the highest for 88.5%.When 10% GCC and 0.8% CS-PDMC were added to the pulp, the drainage rate was the fastest for 0.91 mL/s; when 5% kaolin and 0.8% CS-PDMC were added to the pulp, the drainage rate was the fastest for 0.83 mL/s. It indicated that using a certain amount of CS-PDMC was of benefit to the retention and drainage properties of the furnish containing the fillers. |
