  • Is magnafloc a polyacrylamide homopolymer?
  • 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.
  • How does polymer concentration affect the behavior of PHPA fluids?
  • Recall that PHPA fluids are solutions of synthetic polymers not clay suspensions and thus they can be expected to display different behavior. As regards the effect of polymer concentration, it can be seen from Fig. 6 that as the concentration increases, the values of both moduli also increase.
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
  • Does encapsulation of cutting particles based on PHPA polymers prevent flocculation?
  • Conclusions The effective encapsulation of cutting particles suspended in drilling fluids based on PHPA polymers severely limits (if not prevents) subsequent flocculation by dosing similar anionic flocculants.
