Copolymer composition for particle aggregation - Roa-espinosa, Aicardo
A composition for erosion control, dust abatement, and/or water clarification comprising an anionic polyacrylamide, and at least one inorganic salt, wherein the combination of the anionic polyacrylamide and at least one inorganic salt form a
Many researchers have studied cationic copolymerization of anionic polyacrylamide using “H 2 O”/KPS initiator system and CH 2 Cl 2 solvent [19, 20]. Frequently, these initiators require the use of very high or very low temperature and high

A method for suppression of particulate matter utilizing an aqueous solution containing a non-irritant surfactant and a polymer. The surfactant is either an amphoteric surfactant alone or in combination with an anionic surfactant. The polymer is
- Does salt filler affect anionic Polyacrylamide (a-Pam)?
- An anionic polyacrylamide (A-PAM)/salt filler solution for wastewater treatment utilizing 10 wt%, 20 wt% and 30 wt% loadings of CO (NH 2) 2, KCl, NaCl, and Na 2 SO 4, was prepared. The effects of different types of salt fillers and salt filler loadings on anionic polyacrylamide (A-PAM) were experimentally studied on kaolin.
- What is an anionic Polyacrylamide (a-Pam)/salt filler solution for wastewater treatment?
- Conclusion An anionic polyacrylamide (A-PAM)/salt filler solution for wastewater treatment utilizing 10 wt%, 20 wt% and 30 wt% loadings of CO (NH 2) 2, KCl, NaCl, and Na 2 SO 4, was prepared.
- Can polyelectrolyte complexes encapsulate filler particles?
- In this study, filler modification was carried out by sequentially adding an anionic polyacrylamide, a cationic starch and a cationic polyacrylamide. It is believed that in this process, multiple polyelectrolyte complexes are formed which can not only encapsulate filler particles but also preflocculate the particles.
- Can anionic polyacrylamide improve the rheological properties of cement mortar?
- Some scholars have found that anionic polyacrylamide (APAM) can not only improve the rheological properties of cement mortar, but also help control its plastic shrinkage cracking, which can improve the flexural strength and bond strength of mortar , .
