Decreases in water content are sometimes observed while grinding solids containing essential water in the form of hydrates, likely as a result of localized heating. (See Section 12.3.1.2 for a discussion of the types of moisture present in solid samples.)

Preparation of Solid Dispersion. Preparation of solid dispersion TMS and HPMC E5 LV was conducted using co-grinding method in a planetary ball mill (Fritsch, Pulverissete 7, Germany) at 500 rpm.

Dispersion addi-tives improve the stabilization of the pigment dispersion. One and the same product can often function as both the wetting and the dispersing additive. Additives will not help in step 2, the actual dispersion of the pigment agglomerates, even if the term "dispersion" additive would suggest the contrary. Here it is importantGrinding is the first step of mechanical material removal. Proper grinding removes damaged or deformed surface material, while limiting the amount of additional surface deformation. The goal is a plane surface with minimal damage that can easily be removed during polishing in …

DOI: 10.1016/0032-5910(93)80020-b [6] Rajendran Nair P B, Paramasivam R. Effect of grinding aids on the time-flow characteristics of the ground pround product from a ...The wet grinding process occurs when a product is transformed from solid to liquid, regardless of its viscosity: paints, inks, enamels, nail varnish, among others. In this process, agglomerates that were not separated in the dispersion phase (due to the electro-physical bonding of some components) are broken by applying extra energy.. This wet grinding process uses beads or …

For Mark Traber, Director of Global Sales of Grinding & Dispersing, this is a very exciting project. "The design of an efficient process solution starts in the lab. We simulated the production lines beforehand on a laboratory scale using dispersion …If this pigment grinding step is not optimized, a wide variety of defects can occur: Flocculation Gloss reduction Color shift Separation, formation of Bénard cells Settling.

The s-Jet ® System (patent pending) is a new innovation in a line of consistent developments being made in the area of air jet milling. Final finenesses in the submicron range (example: d 50 0.2 µm) can now be achieved with fluidized bed jet mills. As opposed to conventional dry grinding processes with fluidized bed jet mills, the s-Jet ® System uses superheated steam as its milling gas.Dispersion process. Pigment wetting: The air and moisture covering the pigment is replaced by the resin solution. The solid/gas interface (pigment/air) is transformed into a solid/liquid interface (pigment/resin solution). Grinding stage: By high shear forces the pigment agglomerates are broken up into smaller units, preferable primary particles.
