Abstract

Die Erfindung betrifft ein Verfahren für das Herstellen von porösen Körnern aus Wasserglas indem getrocknete Partikel aus Wasserglas durch einen Erwärmungsvorgang zufolge Schmelzens und Verdampfens von eingeschlossenem Wasser aufgebläht werden. Im optimalen Verfahrensablauf wird ein einzelnes Partikel durch Erhärten eines einzelnen Massetropfens gebildet; in der zum Aufschäumen führenden Erwärmungsstufe werden die Partikel und die sich daraus bildenden porösen Körner durch Mikrowellenstrahlung erhitzt und gleichzeitig dabei über einem Fließbett gehalten und bewegt.The invention relates to a process for the preparation of porous grains of water glass by drying dried particles of water glass by a heating process after melting and evaporation of trapped water. In the optimal procedure, a single particle is formed by hardening a single drop of mass; In the heating step leading to foaming, the particles and the porous grains formed therefrom are heated by microwave radiation while at the same time being held above a fluidized bed and moved.
