Abstract
(DE)
Beschrieben wird ein quellfähiges Schichtsilicat auf Smektit- oder Sepiolith/Palygorskit-Basis zur Verwendung in die Quellfähigkeit herabsetzenden, zwei- oder mehrwertige Kationen enthaltenden Medien, gekennzeichnet durch ein Quellvolumen von etwa 5 bis 50 ml, gemessen durch Zugabe von 2 g Schichtsilicat (atro) zu 100 ml Wasser, und durch eine Feinheit von maximal 5 Gew.-% > 40 $g(m)m bzw. maximal 20 % > 20 $g(m)m, als Trockensiebrückstand.
(EN)
The invention relates to a swellable phylloscilicate on the basis of smectite or sepiolith/palygorskite for use in media that reduce swellability and that contain bivalent or polyvalent cations, characterized by a swelling volume of about 5 to 50 ml, measured by adding 2 g phyllosilicates (absolutely dry) to 100 ml water, and by a fineness of maximally 5 % by weight > 40 $g(m)m or maximally 20 % > 20 $g(m)m, as the dry screening refuse.
(FR)
L'invention concerne un silicate en couche expansif à base de smectite ou de sépiolithe/palygorskite destiné à être employé dans des milieux abaissant le pouvoir expansif, contenant des cations bivalents ou plurivalents. Ledit silicate en couche est caractérisé par un volume d'expansion de 5 à 10 ml, mesuré par addition de 2 g de silicate en couche (absolument sec) à 100 ml d'eau, et par une finesse maximale de 5 % en poids > 40 $g(m)m, ou 20 % > 20 $g(m)m en tant que résidu de criblage à sec.
