  • Do cationic polyacrylamides affect fines retention and drainage?
  • In this study, effects of various retention agents on fines retention, drainage and formation were examined using linerboard stock in the laboratory. Among the retention aids tested, high molecular weight cationic polyacrylamides showed good efficiency both in retention and drainage.
  • Can polyacrylamide be used as a drainage aid?
  • When used as a drainage aid, polyacrylamide can overcome slow drainage of fiber furnishes containing high-yield pulps such as stone groundwood, hardwood pulps and recycled fiber furnishes. In addition, these additives improve the drainage of high-base-weight paperboard furnishes and drainage of paper machines that are drainage limited.
  • How do polymeric additives affect drainage rate and fines retention?
  • A considerable amount of information has been reported on how various polymeric additives affect drainage rate and fines retention. When used as a drainage aid, polyacrylamide can overcome slow drainage of fiber furnishes containing high-yield pulps such as stone groundwood, hardwood pulps and recycled fiber furnishes.
  • Do polymeric retention aids improve papermaking system closure?
  • On the other hand, high charge density, low molecular weight polymeric retention aids showed little improvement both in retention and drainage. The best retention system selected from the laboratory experiment was applied on a paper machine producing linerboard to evaluate its effect on papermaking system closure.
