    摘要: A process for creating readily or highly dispersible nanoparticles on which chemically reactive functional groups or ligands have been placed. An ultra-high shear fluidic processor is used to change the size distribution of nanoparticle agglomerations and facilitate the formation of stable dispersions of such nanoparticles, as well as the placement of various chemically reactive functional groups or ligands on exposed surface areas of such nanoparticles. Such functionalized nanoparticle agglomerations have a broader size distribution (with a substantial increase in the proportion of smaller agglomerations), can exhibit enhanced dispersion characteristics and, when dispersed in various bulk materials, can impart to such bulk materials the desirable physical or chemical properties associated with the selected chemically active functional groups that have been attached to the surface areas of such agglomerations.

    摘要: Disclosed herein is a method of forming pigment pseudoparticles from pigment particles, comprising polarizing the pigment particles with a gas and agglomerating the polarized pigment particles to form pigment pseudoparticles. Also disclosed herein is a pigment pseudoparticle comprising pigment particles bonded together primarily by an induced level of intermolecular electrostatic attractive force, wherein the pseudoparticle is substantially free of internal dust. Furthermore, an apparatus is disclosed herein for creating pigment pseudoparticles from pigment particles, the apparatus comprising a hollow vessel having an inner cylindrical surface, a plurality of scoops extending inwardly from the inner surface and positioned along the axial length of the hollow vessel and means for passing pigment particles through the gas. Additional embodiments of the invention are disclosed herein.

    摘要: Titanium Dioxide and other pigments or powders processed by this present process are smoothly discharging, low dusting, agglomerated, compaction resistant, extremely friable and fully dispersable. The process for the production of smoothly discharging pigment or powder consists of gently blending in the presence of an air flow and an electrostatic charge where said pigment or powder is being agglomerated with or without a treated or non-treated seed particle of the same or similar pigment whereas said pigment or powder in accordance with the invention yields a composition of a substantially spherical particulate that has a pseudo-particle size of 0.1-5.0 mm in the form of smoothly discharging, low dusting, non-sticky, agglomerated, compaction resistant pigment or powder, in which said pigment or powder particles are 80%-99.9% by weight, pigment, and in which the pigments or powders are compatible with inks, paints and plastics, and can be readily dispersed and incorporated into the same.
