Abstract

Cette invention concerne des procédés de fabrication de papier, y compris des procédés microparticulaires, dans lesquels on utilise la bentonite sous forme d'un concentré, ou d'une dispersion diluée obtenue par dilution de ce concentré. Le concentré est une dispersion contenant de 15 à 40 % en poids de bentonite dans l'eau contenant du citrate; ce concentré a une viscosité inférieure à 5000cps et est un fluide stable. Ces concentrés sont nouveaux. Ils sont de préférence obtenus par le mélange de bentonite alcalino-terreuse avec de l'eau et du citrate de sodium.
