Filled paper pulp sizing features in the presence of polyelectrolyte
It is shown that to reduce the size of the filler particles from 3–5 microns (natural) to 0.65–0.82 microns ({[CaCO3]m· nCO3 2– · (n – x)Na + } x– · xNa + ) allows for the filling process in geteroadagulation and penetration. To obtain high elevated paper with high-hydrophobic and strength properties it is advisable to sequentially introduced into the pulp slurry, calcium chloride and sodium carbonate to obtain superfine particles of filler (consumption10% of a. d. f.), then polyethylenimine (consumption 0.075% a. d. f.) and adhesive based on alkylketenedimer AKD (consumption 0.5% a. d. f.) demonstrating flocculating and sizing effect respectively
