Bulgaria Good Quality Solid Particle Type High Viscosity Polyacrylamide

Under optimal conditions, microspheres with the particle size of 38.0 ± 0.2 μm showed good sphericity, storage stability and a narrow particle size distribution.

Feb 01, 2022 · High foam viscosity and therefore higher stability in presence of particle gels. The gel enhanced foam was reported to be suitable in high-temperature oilfields. Zhao et al. Sparging: Gel: Micron dispersed particle gel (DPG) 1000–3000: N 2: Tetradecyl hydroxyl sulfobetaine (THSB) 30,000 NaCl 10,000 MgCl 2 10,000 CaCl 2: 75 – –

Jun 12, 2013 · The particles are plate-like and the aspect ratio (particle diameter/particle thickness) is about 5–15. There is a significant difference in the chemical composition of the edges and the basal ...

High pressure homogenization of the pre-emulsion is done above the lipid melting point. Usually, lower particle sizes are obtained at higher processing temperatures because of lowered viscosity of the lipid phase, although this might also accelerate the drug and carrier degradation. Better products are obtained after several passes through the ...
