Title
(EN) METHOD AND DEVICE FOR MAKING AN AQUEOUS FOAM
(FR) PROCÉDÉ ET DISPOSITIF POUR FABRIQUER UNE MOUSSE AQUEUSE
Abstract
(EN)
A method and device for making foams and slurries using an assembly of pins having rigid and flexible segments, a rotor shaft, and a container than can be easily assembled and disassembled. According to one embodiment of the present invention, a method for making a foam includes at least the following steps: (a) feeding one or more reactants (e.g., an aqueous solution) and one or more optional additives into a container having an open top, a closed bottom, and a wall, wherein a rotor shaft is inserted into the top of the container; (b) rotating the rotor shaft to mix the solution; and (c) forming a foam (e.g., an aqueous foam).
(FR)
L'invention concerne un procédé et un dispositif pour fabriquer des mousses et des suspensions qui utilisent un ensemble de tiges ayant des segments rigides et flexibles, un arbre de rotor et un récipient qui peut être facilement assemblé et désassemblé. Selon un mode de réalisation de la présente invention, un procédé pour fabriquer une mousse consiste au moins à : (a) introduire un ou plusieurs réactifs (par exemple, une solution aqueuse) et un ou plusieurs additifs facultatifs dans un récipient ayant une extrémité supérieure ouverte, un fond fermé et une paroi, un arbre de rotor étant inséré dans la partie supérieure du récipient ; (b) faire tourner l'arbre du rotor pour mélanger la solution ; et (c) former une mousse (par exemple, une mousse aqueuse).
