What is nonionic polyacrylamide?

Nonionic polyacrylamide is widely applied in the field of building materials as an external additive for concrete, which can improve the interaction between concrete particles and thereby the strength and toughness of concrete is increased.

Can nonionic polyacrylamide be used as a sewage treatment agent?

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.

Is cationic polyacrylamide suitable for suspending materials with negative charge?

Cationic polyacrylamide is suitable for suspending materials with negative charge and organic matter.

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.

Which reagent is used to degrade polyacrylamide in aqueous solution?
