Quadro Comil conical screen mill is especially suited to heat-sensitive materials and to dispersing
wet and dry materials before extrusion or other processing steps in order to reduce preblending time and improve final blends.
The addition of Premier Mill will advance NETZSCH's position as the leader in wet and dry fine grinding technology with the most comprehensive lines of processing equipment," said Dimitrios Makrakis, managing director of the Germany-based NETZSCH Business Unit Grinding & Dispersing
Other TEGO Dispers wetting and dispersing
additives can be used in combination to promote the performance of TEGO Dispers 1010.
The problem in the past has always been dispersing
the particles to maximize their effectiveness.
BASF Coatings has obtained a patent for a process for preparing a powder coating material comprised of mixing at least two liquid components in a static mixer to give a molecularly disperse and/or finely dispersed liquid mixture, emulsifying the liquid mixture in an aqueous medium in a dispersing
unit to give an aqueous emulsion of liquid particles, and one of cooling the emulsion so that a suspension of dimensionally stable particles is formed, and isolating the dimensionally stable particles from the suspension, or isolating dimensionally stable particles directly from the emulsion.
DuPont initiated studies to define a method to disperse para-aramid pulp into rubber, and this effort led to development of a unique new technology platform for dispersing
pulp into an elastomer matrix.
The result: a stable patchwork of burning and protected regions, whose specific pattern depends both on the fires' strength and on the direction and rate of the moisture dispersing
from flaming patches.
Tegomer P121 and P131 dispersing
additives for organic and inorganic pigments are amphiphilic block copolymers that reportedly reduce the amount of pigment required to achieve a certain color strength.
Dry mixing silica has the further difficulty of wetting and dispersing
an initially incompatible material in the rubber.
Some scientists have maintained that cloud seeding -- the practice of dispersing
chemicals into cumulus clouds in order to make rain -- is about as effective as paying someone to do a rain dance.
has obtained a patent for a water-based pigment dispersion comprised of a pigment dispersing
resin, pigment, aqueous medium, other pigment dispersing
resin and, optionally, dispersing
