PTT/EMMA-GMA and PTT/(EMMA-GMA/EMAA-Zn(4/1)) showed improved phase miscibility between the dispersion phase
and PTT matrix resin attributed to the chemical reaction between epoxy group in EMMA-GMA and end groups in PTT.
In this study, dispersion phase
diagrams (DPDs) were constructed for four commercial paint formulations.
The liquid dispersions (LDs) consist of dispersion medium (most often water) and dispersion phase
. In the dispersion phase
, the LDs there are particles with larger and particles with smaller volumetric mass density than the average density of the dispersion medium, which we shall call heavy particles and light particles.
Next, they adsorb onto the primary pigment particle during the dispersion phase
. Last, they provide a stable suspension that ideally resists flocculation, reagglomeration and viscosity increase for an extended period.
Earlier work in this series introduced the dispersion phase
diagrams (DPD) for latexes (2,3) and pigments.
This course covers the chemistry, physics and mechanical processing aspects of the dispersion of pigments and resins in fluid media, along with methods to characterize, analyze and assess dispersion quality, mad provides an understanding of dispersion phase
For the binary blends, increasing of elastic modulus in the low frequency region could be successfully predicted by Palierne's model, and this relaxation process in the low frequency region was interpreted as the effect of the deformation of dispersion phase
In the dispersion phase
(Figure 2), mechanical energy is used to break up chunks, clumps, and clusters.
Pigment dispersion phase
diagrams represent a good way to visualize the complex interactions among pigments, dispersant, and thickener.
Associative Polymer/Particle Dispersion Phase
Diagrams III: Pigments--E.
diagrams have been developed to help visualize these interactions.
