Investigation on the particle size distribution of O/W emulsions

Investigation of the dependence of rheological characteristics on the parameters of particle size distribution at O/W emulsions

“…Experimental testing proved term [5] to be particularly satisfactory for the emulsions differing among themselves in dispersed oil concentration, homogenization duration, kind of homogenizer as well as in other factors influencing particle size distribution.…”

“…Previous investigations (5) have shown that in the process of homogenization particles of dispersed phase (oil) tend to take some characteristic diameter X, and that the rate of particle number n changes with their diameter XI dn n -a -x (x -x) [q If we keep in mind the fact that the homogenization process is the result of events by chance, .52 is the most probable or the most frequently represented diameter of the particles, and the parameter a is constant of the rate of homogenization.…”

“…By means of parameters of the flow equation [5], using the regressions [7], [8] and [9] it is possible to calculate the parameters of particle size distribution equation [2], Therefore one may compare the particle size distribution parameters obtained by experimental measurement, by the distribution equation [2], and by the parameters of the flow equation [5].…”

“…Concerning these considerations parameters of flow equation [5] '7o and ~lv proved to be in a mutual functional dependence with the parameters of particle size distribution equation [2]. This dependence is on one hand proportional to a specific surface S and on the other in inverse ratio to the first degree of the surface mean particle diameter ~.…”
