Abstract

A találmány tárgya folyamatos eljárás poliszilikátmikrogélelőállítására. A találmány szerinti eljárás lényege, hogy egymás utána) elkeverik egy vízben oldható szilikát vizes oldatát és egygéliniciátort egy keverőedényben, és így mintegy 0,5-15 tömeg%szilícium-dioxidot tartalmazó vizes elegyet állítanak elő, és b) azelegyet egy nyújtott öregítőedényben részleges gélesedésig öregítik,ahol a keverőedény és/vagy öregítőedény elasztikusan deformálható, ésa folyamat alatt ideiglenesen deformálásra kerül az edény falánkialakuló lerakódások elmozdítása és az edényből történő kiürítéseérdekében.
