Abstract

CATIONIC STARCH is widely used in papermaking as dry-strength additive. By developing the use of nanoparticles in recent years, adding nanoparticles to some common papermaking high mass polyelectrolytes, is widely applied to improve drainage and simultaneously RETENTION of fine materials and fillers. However, there is still little knowledge about this phenomenon and the performance mechanism of these additives in relation with other variables. In this study the performance of anionic NANOSILICA PARTICLES at different CATIONIC STARCH dosages and their relation with zeta potential was investigated in terms of RETENTION and DRAINABILITY in FINE PAPER furnish. The results showed that 0.5% CATIONIC STARCH, by itself, increased the DRAINABILITY just up to about 12 ml (CSF) and then even decreased it at higher dosage levels. The same trend was also observed in RETENTION of fines and fillers with the highest figure (41%) at 1% CATIONIC STARCH dosage. NANOSILICA PARTICLES addition modified this mild trend and significantly improved drainage and RETENTION with better performance at higher CATIONIC STARCH dosage while zeta potential was still negative. A reduction in nanosilica performance was observed when higher CATIONIC STARCH dosage resulted in wet end system positive charge. Therefore, zeta potential can be a good indicator in determining CATIONIC STARCH dosage.
