What is anionic polyacrylamide (Apam)?

Anionic Polyacrylamide (APAM) has a linear-chain structure. Amide group has a high chemical activity which can forms a series of derivatives with many kinds of compounds. Anionic Polyacrylamide (APAM) has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale.

What is anionic polyacrylamide used for?

Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Anionic polyacrylamide is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a Ph value of neutral or alkaline solution.

Can nonionic polyacrylamide be used as a sewage treatment agent?

Nonionic polyacrylamide can be used as a sewage treatment agent for acidic slurry, making the suspended particles flocculate and precipitate. * You have to Login or Register to download this file.

What is polyacrylamide used for?

Polyacrylamides are water-soluble synthetic linear polymers made of acrylamide or the combination of acrylamide and acrylic acid. Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment.

Does Apam have imidization reaction in strongly acidic ph2.5?

Anionic Polyacrylamide (APAM) will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water.

What is cationic polyacrylamide used for?

Cationic polyacrylamide can also be used as an oil field chemical additive, such as clay anti swelling agent, thickening agent for oil acidification and paper making reinforcing agent. Nonionic polyacrylamide is suitable for separation of suspended solids in organic and inorganic mixtures, and the solution is acidic or neutral.
