Overview

Randomized trial examines the effect of cationic polyacrylamide molecular weight on filler retention in paper, suggesting optimal conditions for material quality.

Key Points

  • This research investigates how the molecular weight of cationic polyacrylamide affects the retention of mixed talc and GCC fillers with different particle sizes during paper formation.
  • Utilized a wet-end process simulator (WEPS) for industrial sheet formation under vacuum dewatering and vibration conditions.
  • Assessed the relationship between cationic polyacrylamide molecular weight (6-8 million) and filler particle size in paper quality analysis.
  • Larger particle size talc resulted in higher agglomeration and poorer quality compared to smaller particle size GCC.
  • Increasing cationic polyacrylamide molecular weight from 6 million to 8 million worsened paper quality due to restricted polymer adsorption.
  • In a 50:50 mixture, higher ratios of 8 million molecular weight C-PAM increased talc retention, while higher ratios of 6 million increased GCC retention.
