anionic polyacrylamide vs polyamide in albania

  • The difference of anionic, cationic and Non-ionic ...

    2018-3-27 · Polyacrylamide is not the only acrylamide unit, the acrylamide unit is mostly called polyacrylamide. Thus, polyacrylamide may contain structural units that can be ionized or hydrolyzed in water to carry charges. As a result, there are cationic, anionic, non-ionic, amphoteric ion type of various polyacrylamide anionic polyacrylamide

  • Chemical flocculants - Kemira

    Anionic polyacrylamides are easier to polymerize to very high molecular weights. We produce anionic powder flocculants polyacrylamides (ADPAM) with anionic charge density ranging from 0-100%. We also offer anionic inverse emulsion (AEPAM) flocculants in a standard range plus in extremely high molecular weight via Kemira’s proprietary emulsion hydrolysis technology.
