What is nonionic polyacrylamide?

Nonionic polyacrylamide is a high polymer with a high molecular weight and a low ion exponent, which has the function of flocculation, dispersal, thickening, bonding, film-forming, relating, and colloidal stability. Its flocculation is hardly influenced by the PH value and the salt, and in the process of acid wastewater

What is nonionic polyacrylamide (NPAM)?

Nonionic polyacrylamide (NPAM) is a type of high molecular polymer or polyelectrolyte. Its molecular chain contains nonionic polar groups that can adsorb suspended solid particles in water and bridge them to form a large flocculate.

Is non ionic polyacrylamide a water soluble polymer?

Non-ionic polyacrylamide is a water-soluble high molecular polymer or polyelectrolyte. The characteristics of nonionic polyacrylamide PAM can be simply divided into the following three points: It has relatively good water solubility and can be completely dissolved even in cold water.

What are the functions of nonionic polyacrylamide PAM?

Therefore, nonionic polyacrylamide PAM has the functions of flocculation, dispersion, thickening, adhesion, film formation, gelation, and colloid stability. Nonionic polyacrylamide PAM is mainly used for flocculation and sedimentation of various industrial wastewater, and clarification and disposal of precipitation.

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.

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.
