Estimating the Shear Resistance of Flocculated Kaolin

A low shear rate limits the dispersion and contact between particles and flocculant chains. Therefore, the flocs formed do not reach an adequate settlement. At the same time, an excessive shear causes the detachment of the polymer chains from the particles and breakage of particle–flocculant–particle bonds, impacting the size and structure

When comparing filler retention under optimal flocculation conditions, we found similar filler retention for all retention aids. Salt did not affect drainage for cationic retention aids, but reduced the drainage rate for PEO. Drainage with PEO was considerably slower than for other retention aids.

Effect of Shearing Forces and Flocculant Overdose on Filler

The effects of both shearing and flocculant overdose on filler flocculation kinetics and mechanisms and floc properties, in the absence of fibers, are presented. The flocculation by cationic polyacrylamide (CPAM) or poly(aluminum chloride) (PAC) was determined using a focused beam reflectance probe.

Evaluation of flocs resistance and reflocculation capacity

Some experiments were also performed on thermomechanical pulp and de-inked pulp fibres. Flocculation was measured by a focused beam reflectance measurement probe. It was found that flocs induced by polyethylene-oxide (PEO) and cofactor broke up with time and shear and could not be reformed subsequently.

Effect of Shearing Forces and Flocculant Overdose on Filler

The effect of shear forces on aggregation kinetics depends on particle size. PAC produces soft flocs. At 250 rpm, the number of counts decreases due to flocculation, while, at 750 rpm, flocculation of particles smaller than 0.5 μm increased the number of counts.
