The invention relates to a method for producing a foam, especially a foamed porous light-density material, in which a slurry that contains a carrier liquid and a foaming agent as well as optionally containing additional additives such as retarders, accelerators, stabilizers, liquefiers, binders and fillers is converted into a foam or light- density material by adding a gas. According to the invention, the slurry is firstly fed into an intermediate reservoir out of which it is transported to a foaming device which is arranged downstream and which comprises an air supply valve that can be regulated.
L'invention concerne un procédé de production d'une mousse, en particulier d'une matière légère poreuse moussée. Selon ledit procédé, on transforme une boue, qui contient un liquide porteur, un agent moussant et, éventuellement, d'autres additifs, tels que des retardateurs, des accélérateurs, des stabilisants, des fluidifiants, des liants et des matières de charge, en une mousse ou en une matière légère poreuse, par adjonction d'un gaz, ladite boue étant d'abord amenée à un réservoir intermédiaire à partir duquel elle est conduite à un dispositif de moussage monté en aval et comportant une soupape d'amenée d'air régulable.
