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?

3. Nonionic Polyacrylamide (Nonionic PAM, NPAM) Structure and Properties: Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain.

How is non ionic polyacrylamide produced?

Non-ionic polyacrylamide may be produced from its monomer by free radical polymerization using a wide variety of initiation methods.

How does non ionic polyacrylamide reduce settling time?

that the addition of 1 mg/l of non-ionic polyacrylamide reduces the settling time from 1230 seconds to about 90 seconds. This has an implication of reduction in the retention time in the settling tanks with corresponding savings in capital investment and producing cleaner water for the subsequent processes. 3. ANIONIC POLYACRYLAMIDE

What is a nonionic polymer (Pam)?

Nonionic PAM is a high molecular polymer or polyelectrolyte with a certain amount of polar genes in its molecular chain. It can adsorb solid particles suspended in water and bridge between particles to form large floccules, accelerate the sedimentation of particles in suspension, accelerate the clarification of solution, and promote filtration.

Does non-ionic polyacrylamide improve floc settling time?

Tan et al. have studied the effect of non-ionic polyacrylamide as a coagulant aid on floc settling time for the removal of colouring matters form industrial dye wastewater. Non-ionic polyacrylamide is commonly used as a coagulant aid to improve the coagulation process and subsequently the floc settling velocity.
