Can nonionic polyacrylamide be used as a gel fracturing fluid?

Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.

What is nonionic polyacrylamide used for?

Nonionic polyacrylamide is suitable for separation of suspended solids in organic and inorganic mixtures, and the solution is acidic or neutral. Nonionic polyacrylamide can be used in textile sizing to improve the viscosity, permeability and desizing performance, make fabric with antistatic properties, and reduce sizing rate and machine damage.

Which polymer uses acrylamide as a monomer?

which use acrylamide as their basic monomer. Polyacrylamides can either be nonionic, anionic, or cationic. The nonionic polymer is made solely from acrylamide monomer, while the anionic form also uses an acrylic acid monomer, and the cationic form also uses a cationic acrylamide based salt monomer (e.g. ethanaminium, N,N,N-tr

Is acrylamide cationic or nonionic?

can either be nonionic, anionic, or cationic. The nonionic polymer is made solely from acrylamide monomer, while the anionic form also uses an acrylic acid monomer, and the cationic form also uses a cationic acrylamide based salt monomer (e.g. ethanaminium, N,N,N-tr methy1-2-[(1-oxo-2-propenyl)oxy]-, chloride).Polyacrylamides come in

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.

How to control NPAM molecular weight?

The NPAM molecular weight can be controlled by adjusting these factors. The decisive factor is the acrylamide concentration, whereas the initiator concentration and feeding temperature are secondary factors. These synthetic NPAMs can be crosslinked with zirconium acetate to produce a gel fracturing fluid for use in low permeability oil reservoirs.
