  • Does high-molecular-weight polymer stabilize coal water slurry?
  • The stability of coal water slurry (CWS) is a significant factor affecting its storage and transportation. However, the understanding of the mechanism of high-molecular-weight polymer used as stabilizers in CWS is still limited.
  • What is the difference between Apam and CPAM CWS?
  • When the slurry was exerted with a shear force, the viscosity of CWS was decreased due to the release of a big volume of trapped free water. Thus, the rheological behavior of APAM-cws was the same as Blank-cws. For CPAM-cws, the slurry was still characterized as the pseudoplastic fluid, but this feature was weakened a lot.
  • Which polymer has a high affinity with polycyclic aromatic hydrocarbon?
  • PAM is a long-chain linear structure polymer with carbon-carbon double bonds, which has a high affinity with polycyclic aromatic hydrocarbon of coal surface . PAM can be adsorbed on the surface of coal particles due to this driving force, and the side chain groups are exposed to the surrounding solution.
  • What is the molecular weight of template poly (allylammonium chloride)?
  • Besides, template poly (allylammonium chloride) (PAAC) was obtained from Shandong Xintai Water Treatment (Zaozhuang, China), and its molecular weight (MW) was 4200. The above reagents were of analytical grade except for AM and SAS (technical grade).
