Mechanically stirred vessels with solidliquid suspension system have been widely used in chemical and biological reaction processes, such as polymerization, chemical deposition, catalysis and crystallization 1,2,3,4.in order to obtain the desired products, it is necessary to create a fine dispersibility and maintain the dispersion stability of the suspension during the reaction.
A scalable process for delamination of hexagonal boron nitride in an aqueous solution of the non-ionic surfactant tween85 using a stirred media mill is presented. the size of the zro2 beads used as grinding media governs the dimensions of the ground boron nitride particles as atomic force microscopic investigations afm reveal the mean flakes thickness decreases from 3.5 to 1.5 nm and the.
As liquid phase fluids of high viscosity like glycerol and two different epoxy resins were used. glycerol shows a polar behaviour, whereas the epoxy resins show a more non-polar behaviour. additionally, hardening of the deagglomerated samples for additional scanning electron microscopy ... stirred media mill dispermat sl see figure 3 with a.
The invention relates to a dispersing process in which a mill base consisting of solids and of a liquid phase is conveyed through a stirred ball mill containing a grinding medium, energy is supplied in this stirred ball by rotating rotors, and the solids are dispersed, and wet with the liquid phase, wherein the rotors rotate at such a high speed that the grinding medium moved by them forms, as.
