Flocculating fine cuttings particles suspended within partially hydrolysed polyacrylamide (PHPA) solutions used as drilling fluids in mineral

Magnafloc? 800HP (BASF) is nominally a polyacrylamide homopolymer, although may contain up to 1 % of anionic functionalities. Fig. 3 b shows that in contrast to anionic flocculants, applying the nonionic 800HP at a dosage of only 56 g t ?1 was able to induce significant aggregation of solids within the drilling fluid.

Insight into the Synergic Effect of Partially Hydrolyzed Polyacrylamide and Nanosilica on Sodium Silicate Sealant Gel System for Water

Moreover, partially hydrolyzed polyacrylamide anionic (PHPA) could reduce the possibility of syneresis and improve the thermal stability of the Na-silicate gel []. Gelation time is considered the most complicated parameter, because it is affected by many factors such as temperature, activator concentration, salinity, and mechanical shear rate.

anionic polyacrylamide

ANIONIC POLYACRYLAMIDE

Anionic polyacrylamide is the copolymer of acrylamide and acrylic acid. No studies on the environmental fate of polyacrylamide are available. As a high-molecular weight, water-soluble polymer, it is not expected to biodegrade or bioaccumulate. Anionic polyacrylamide has a low acute toxicity concern to aquatic organisms.

polyacrylamide

Polyacrylamide

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]
