grinding of polymers in mizoram

Grinding postindustrial or downgraded material to a powder can enable product to be re-introduced or mixed with a polymer in production or polymerization. This effectively upgrades the postindustrial material and increases the overall value of the product.

Use of the co

The solid dispersion (SD) technique is the most effective method for improving the dissolution rate of poorly water-soluble drugs. In the present work, SDs of the Ca2+ channel blocker dipfluzine (DF) with polyvinylpyrrolidone K30 (PVP) and poloxamer 188 (PLXM) were prepared by the powder solid co-grinding method under a solvent-free condition.

Metal Grinding in the Presence of Mechanically Degradable

Oct 15, 2013Grinding of metal swarf in the presence of a mechanically degradable high-molecular compound intensifies the size-reduction and plasticizing processes and is accompanied by reduction reactions and desulfurization of metal particles. Mechanically degradable organics are used as solid-phase high-molecular compounds to promote metal grinding. A high-energy vibrating mill is employed to grind

The original near-spherical shape of the polymer powders was retained and such shape and morphology of these powders exhibited proper flowability and were preferable in the layer-by-layer deposition [18,21]. Besides, CNTs were able to assemble uniformly onto the surface of polymer powders and form a network structure as shown in Figure 2d.
