  • Why is cationic fragment structure important in a template copolymer?
  • The cationic fragment structure in the template copolymer could help to generate large and dense floc structure and form stable drainage channels. Under external pressure, these large and compact floc structures had greater compressive resistance, which avoided deformation and blockage of drainage channels and voids.
  • What happens when cationic monomers are added to cpamd?
  • When the anionic template sodium polyacrylate (NaPAA) is added to the reaction system of CPAMD, cationic monomer DAC can be adsorbed to NaPAA by electrostatic force, and then, cationic monomers will be continuously arranged along the molecular chain of the template, thereby forming precursors with cationic microblock structure (Guan et al. 2014).
  • Does tpamd have cationic microblock structure?
  • The template copolymerization mechanism is explored by K M and polymerization kinetics. The chemical structure characterization and analytical results indicated that TPAMD had obvious cationic microblock structure synthesized by MV-TP. The polymerization mechanism was assigned to I Zip-up (ZIP) and free radical initiated polymerization.
  • Can cationic microblock structure improve sludge neutralization and electrical patching?
  • It was speculated that this phenomenon was caused by the cationic microblock structure in TPAMD. It could greatly improve the ability of electric neutralization and electrical patching. The surface charge and electrostatic repulsive force of sludge colloid particles would be rapidly reduced at a relatively small dosage.
