FAQ - Technical & Supply Chain
-
Q:
Does CAS 9003-05-8 identify one universal Polyacrylamide grade?
A: No. Commercial PAM products can be anionic, cationic, nonionic or amphoteric and are supplied as powders or emulsions across different molecular-weight and charge ranges. The CAS number alone is insufficient; state the ionic type, form and application when requesting a grade. -
Q:
What is Polyacrylamide used for?
A: Polyacrylamide is used in water and wastewater treatment, sludge conditioning, mineral processing, papermaking and selected oilfield or process applications. The required charge type and molecular weight depend on the specific water, sludge or process chemistry, so the application should be stated when selecting a grade. -
Q:
How should anionic, cationic, nonionic and amphoteric PAM be selected?
A: Match the polymer charge to the suspended solids and process conditions. Anionic PAM is widely used with mineral or inorganic suspensions, cationic PAM is more common for organic sludge, nonionic PAM suits low-charge systems, and amphoteric grades are used where both positive and negative interactions matter. -
Q:
Which physical and grade parameters should be confirmed for Polyacrylamide?
A: Confirm ionic character, molecular-weight or viscosity range, hydrolysis or charge level, active or solid content, residual acrylamide, particle size and dissolution time. Powder grades commonly target about 88-90% or higher solid content, with bulk density around 0.75-1.05 g/cm3 and low residual acrylamide depending on grade. -
Q:
What is the correct way to prepare a Polyacrylamide solution for dosing?
A: Add the PAM gradually to clean water with continuous mixing at a moderate speed, avoiding high-shear or overdosing that can degrade the polymer or form lumps. Allow enough dissolution time and dilute to the working concentration before dosing, matching the make-down equipment to the powder or emulsion form.
