| Description
| - Kaolinit je obecně užíván v papírenské výrobě k potahování celulózových vláken a také jako plnivo v plastikářské technologii. Z tohoto důvodu je velmi důležité, aby částice kaolinitu nekoagulovaly. Ve snaze vytvořit stabilní koloidní systém byla změněna povrchová struktura tak, že se objevily silné odpudivé síly mezi částicemi. Tento článek byl sepsán, aby popsal povrchové změny komerčně vyráběného kaolinitu (SPS China Clay, Imerys Ltd, Cornwall, UK) po úpravě vyžíháním v muflové peci a ošetření radiofrekvenční plasmou. Efekt povrchových úprav na změnu zeta-potenciálu kaolinity byl zkoumán elektroforetickým a elektroakustickým měřením. Pro elektroforetická měření byl použit ZetaPlus (Brookhaven Instruments), pro elektroakustická měření Acoustosizer II (Colloidal Dynamics). Žíhání kaolinitu vede ke snížení velikosti zeta potenciálu při neutrálním pH a potenciál zůstává negativní přes celé zkoumané pH spektrum 2,75-10. Izoelektrický bod nebyl nalezen ani jednou z použitých technik, minimální hodnota (cs)
- Kaolinite is commonly used as a coating in the paper industry, and as a filler in the plastics industry. Therefore it is crucial that the particles are not flocculated. In order to achieve a stable system the surface chemistry is manipulated such that strong repulsive inter-particle forces are present. This paper then investigates the changes in the surface chemistry of a commercial kaolinite (SPS China Clay, Imerys Ltd, Cornwall, UK) after treatment in a muffle furnace and in a glow-discharge plasma. The effect of the surface treatment on the zeta potential of the kaolinite was investigated using electrophoretic and electroacoustic means. A ZetaPlus (Brookhaven Instruments) was used for the electrophoretic measurements and the electroacoustic measurements were made using an Acoustosizer II (Colloidal Dynamics). Furnace heating lead to a decrease in the magnitude of the zeta potential at the natural pH, and the zeta potential was always negative over the pH range 2.75 - 10. Both measurements
