Abstract

V diplomski nalogi smo raziskovali mikronizacije zmesi barvil iz malinovega soka in različnih nosilcev s superkritičnim CO2 in mikronizacije ter lastnosti dveh polimerov (polietilen nizke gostote) s superkritičnim CO2 in superkritičnim PROPANOM. Na polimerih smo opravili preliminarne raziskave. Raziskali smo lastnosti njunih tališč in obnašanje pri izpostavitvi visokemu tlaku in temperaturi v propanu. Osredotočili smo se na uporabo šaržne in kontinuirane PGSSTM metode. Mikroniziranim vzorcem barvil malininega soka smo izmerili povprečno velikost nastalih delcev.

Secondary title: Production of powderous products using supercritical fluids
Secondary abstract: In the thesis micronisation of dyes from raspberry juice and various carriers with supercritical CO2, as well as the micronisation and properties of two polymers (low-density polyethylene) with supercritical CO2 and supercritical PROPANE was researched. Preliminary research was conducted on the polymers. An analysis of the properties of their melting-points and their behaviour under high pressure and temperature in propane was performed. The thesis focuses on the uses of ranking and continuous PGSSTM method. The average size of particles of micronized samples of raspberry juice dyes was measured.
