Controlling critical coagulation of pigments and fillers
Particle charge is one of the vital parameters in coating and retention optimization. pH setting and additive control belong to the daily work in that field of wet end paper processing. Simultaneous size probing makes the charge influence on particles obvious. Two kinds of particle charge titrations, zeta potential vs. pH AND zeta potential vs. polyelectrolyte consumption generate comprehensive information. All this is realized in the DUO Stabino® & NANO-flex with efficiency tailored SOPs.
