Retention Aids

RETENTION AID. Composition: The words "retention aid" most often refer to cationic or anionic acrylamide copolymers having molecular mass values in the range of 5 to 20 million grams per mole. These are known to be effective for improving the retention of fine particles during formation of paper.

The Effect of Cationic Polyacrylamide as Retention Aid for

The use of Cationic Polyacrylamide (C-PAM) as retention aid on alkaline papermaking which is sized by AKD has been investigated. In this study, 100% Leaf Bleached Kraft Pulp (LBKP) as a fiber source was refined in a laboratory beater up to 400 mLCSF of freeness and then mixed with paper additives i.e. 0.1% AKD as sizing agent, 15% calcium

performance of cationic polyacrylamides in papermaking


However, since retention has to be balanced with an adequate drainage of the wet web and a good formation of the paper sheet, fibre flocculation should be limited whereas flocculation of fine particles and retention additives should be maximized. In papermaking, cationic polyacrylamides are usually used as retention aids. The efficiency of these

Performance testing of retention aid drainage. The retention efficiency needed to be measured using a dynamic water filter. The wet pulp with a dry fiber mass of 5 g was added to a fiber disintegrator. The ratio of the raw material pulp was LBKP:NBKP = 70:30. The solution was defibrized for 5 min and diluted with water.
