Cationic Paper Filler Sludge Encapsulant for Calcium Carbonate Retention
Product Summary
JHWB-1320 Filler Sludge Encapsulant is a cationic functional polymer emulsion developed for the papermaking wet-end. It effectively bridges fiber and inorganic fillers (calcium carbonate, talc) to enhance retention, improve paper strength, and enable the reuse of filler from white water. Suitable for neutral and alkaline papermaking processes, it helps reduce raw material costs and improves paper machine cleanliness.
Key Selling Points
- Enhanced Filler Retention: With a cationic charge, the polymer forms strong bonds between fibers and fillers, reducing filler loss in white water and cutting mineral raw material waste.
- Recovery of White Water Filler: It encapsulates suspended filler, allowing direct reuse in the pulp system, decreasing the need for new light/heavy calcium carbonate.
- Strength Compensation: The tough connecting structure between filler and fiber helps maintain tensile, ring crush, and surface bonding strength, even at higher filler dosages.
- Process Compatibility: Moderate cationic charge avoids over-flocculation; it works well with AKD sizing, retention aids, and dry strength additives, without causing foaming or sizing issues.
- Improved Paper Appearance: Eliminates filler aggregation, reducing white dots and ash unevenness, upgrading surface quality and product grade.
- Extended Machine Life: Lowers suspended solids in white water, reducing dirt on forming wire, press rolls, and pipelines, thereby prolonging cleaning cycles.
