What is The Effect of Pre-flocculation of Lime Mud by Wet-end Additives on Paper Properties about?
The presence of filler in cellulosic paper usually decreases the paper strength, which has been limiting the filler loading beyond a critical level in papermaking process and increasing production cost accordingly. In order to increase filler content in cellulosic paper without sacrificing paper properties, a novel and brief pre-flocculation process was employed in this study. Specifically speaking, the lime mud (LM) suspension was mixed and pre-flocculated with the commonly used wet-end additives including cationic polyacrylamide (CPAM), cationic starch, and alkyl ketene dimer (AKD) successively before it was added to the paper stock for handsheet preparation. Handsheets filled with the pre-flocculated or native LM were prepared and their properties were compared. The experimental results showed that the pre-flocculation process resulted in larger LM flocs with higher zeta potential and relatively higher filler retention. The tensile strength and bursting strength of handsheets filled with the pre-flocculated LM were significantly improved compared to those of native LM-filled handsheets and the optical properties almost remained the same, but the air permeability decreased.
