Patent

CA 2417773

Expanded perlite products having controlled particle size distribution, methods of producing the expanded perlite products, and methods of use thereof are provided. The expanded perlite product has, for example, a low ratio of standard deviation of particle size distribution to median particle size (for example, less than 0.63) and low median particle size (for example, less than 50 microns). The expanded perlite product may be used in a variety of applications including filter applications.

L'invention concerne des produits de perlite expansée présentant une distribution granulométrique régulée, ainsi que des procédés de fabrication et d'utilisation de tels produits. Le produit de perlite expansée présente, par exemple, un faible taux d'écart-type de la distribution granulométrique par rapport à la dimension granulométrique médiane (moins de 0,63, par exemple) et à la dimension granulométrique médiane inférieure (moins de 50 microns, par exemple). On utilise le produit de perlite expansée dans diverses applications, notamment dans des applications de filtrage.
