What is the dissolution time of Cationic Polyacrylamide?
2026-04-14 10:34:33
The dissolution time of Cationic Polyacrylamide(CPAM)mainly depends on its physical form,molecular weight,ionic degree,particle size,and dissolution conditions.Typical industrial dissolution times are as follows:
1.Powder/Granular CPAM(most common export type)
Normal dissolution time:40–90 minutes under gentle stirring
High molecular weight&high ionic:closer to 60–90 minutes
Low molecular weight&low ionic:around 30–40 minutes
Fully dissolved standard:no visible particles,uniform viscous liquid,no agglomerates
2.Emulsion CPAM(liquid type)
Fast dissolution:3–10 minutes
Used in automatic dosing systems where quick preparation is required
3.Main factors affecting dissolution speed
Stirring speed:moderate stirring speeds up dissolution;excessive speed causes chain breakage
Water temperature:warm water(20–40°C)shortens time;>55°C degrades polymer
Particle size:finer powder dissolves faster
Concentration:usually prepared at 0.1%–0.3%for full dissolution
4.Industrial operation reference
For export and on-site use,powder CPAM is generally considered fully dissolved after 60 minutes of stirring.
