<p>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.</p> |
