NEXT GENERATION HIGH-PERFORMANCE CATIONIC DEWATERING FLOCCULANTS Ades, J-C.1 Zabihian, M.2, Holappa, S.2l, Grönfors, O.2 van Rossum, R.3 1Kemira France, 2 Kemira R&D and Technology, Finland, 3 Kemira Netherlands Abstract The new series of cationic water-soluble flocculants for sludge dewatering, XD-series, has been
Cationic degree represents the number of positive charges in flocculants. Two flocculants PAMC1 and PAMC2 with different cationic degree were compared for HA removal efficiency, and the results are presented in Fig. 3. The cationic degree of PAMC1 and PAMC2 was 20% and 40%, respectively.
Use of new branched polyacrylamides to improve retention
Cationic polyacrylamides of very high molecular weight and with different charge densities and degrees of branching have been investigated as retention aids for papermaking.
The Usage of The Polyacrylamide in The Paper Making – CHINAFLOC. The polyacrylamide PAM worked as the paper strengthening agent and the dispersing agent in the paper making from the recycled papers, in order to keep the strength of the paper tensile, to keep the good performance of the paper products, and also to meet the need of the modern offset printing, you can use the cationic
Preparation and performance of cationic flocculant
Cationic spherical polyelectrolyte brushes (CSPB) take unique highly degree of branching and cationic charged density. And the structure similar to both branched polymers and the cationic charged particles, ensure the fibers with high effective of flocculation and retention-aid during the papermaking [13] , [14] .

Effect of cationic polyacrylamides on the aggregation
This was achieved by pre-treating paper with a cationic polyelectrolyte to control the extent of AuNPs coagulation on paper. A series of cationic polyacrylamides (CPAM) was studied. The effect of CPAM solution concentration, polymer charge density, and molecular weight on AuNPs’ adsorption/aggregation behavior and SERS properties was measured.

Cationic cellulosic derivatives as flocculants in papermaking
The performance of these polyelectrolytes for the flocculation of mineral fillers used in papermaking was tested by laser diffraction spectrometry. The flocculant with the highest degree of polymerization and charge originated the best results, particularly when the filler used was kaolin, proving that water-soluble cationic cellulose

Polyacrylamide Market: By Type (Non-ionic, Cationic, Anionic, and Others), By Application (Water Treatment, Petroleum, Paper Making, and Other Applications) & By Region-Forecast 2025-2025 Global Polyacrylamides Market Professional Survey Report 2025
Modification of calcium carbonate particles with surfactant significantly improves the properties of the calcium carbonate coating on paper. In this study, unmodified and CTAB (hexadecyltetramethylammonium bromide)- and oleate-modified calcium carbonate nanoparticles were prepared using the wet carbonation technique for paper coating. CTAB (cationic surfactant) and sodium oleate (anionic
