Progressive Bubble Generating System Used in Making Cementitious Foam

Номер: US20150122153A1
Принадлежит: AIR KRETE, INC.

A process for producing insulating foam, wherein certain especially small inorganic minerals such as silica fume are directly integrated into bubble fluid to better mechanically strengthen bubbles formed and thus allow the formation of smaller bubbles to be reformed by mechanical means. In this process where these same bubbles are now in some part composed of inorganic solids. A process whereby these minerals are maintained as to their median size and dispersion within the bubble fluid by the following; rotor stator mixing and or a recirculating pump, the inclusion within exotherming calcium-chloride salt, the use of other physical exciters such as hydrogen-peroxide, and by straining out outliers of unwanted size or form. The above mentioned mechanical means is a progressive reforming of bubbles and actualized by a glass bead chamber, a second stage consisting of two screened discs, separated from each other and located at the end of the glass bead chamber, and a third stage chamber presenting itself with a considerably enlarged screen area and having considerably finer meshes than the second stage. This process in its execution results in stronger, smaller and denser bubbles; whereupon when complete hydration has occurred, leaves the smaller solids in their placement within the now open cell structure, and in combination with applied cement from a separate process line, the cured cement foam has a significant registered improvement of insulating qualities as measured by certified R-value tests. 1.
