The method may include selecting a defoaming agent capable of hindering foam formation and reducing foam build-up in an aqueous solution, selecting a carrier material that is at least minimally soluble in the aqueous solution, combining the defoaming agent with the carrier material, and forming the combined defoaming agent and carrier material into a solid defoaming substance.

Abstract: A defoaming method capable of destroying foams generated when a container is filled with drink, or the like, efficiently at a high speed and destroying foams effectively even in the case of a container having a narrow mouth. Liquid surface (6) in a container (1) is irradiated with pulse-like light (2) and a pulse-like sound wave (8) is generated from an irradiated point (7) as a sound source. The pulse-like sound wave thus generated propagates from the sound source as a strong spherical wave to reach a bubble (9) and to destroy the bubble. It can also destroy a bubble located at a place remote from the optical path quickly, thus destroying bubbles efficiently at a high speed. Alternatively, pulse-like light is condensed at a gas portion above the liquid surface and the bubbles can be destroyed with a shock wave generated by breakdown phenomenon.

Abstract: Provided are a deforming method and device that use laser-induced breakdown. The provided method and device make it possible to shorten the focal distance, thereby improving laser beam convergence, and increase the utilization efficiency of sound waves that contribute to defoaming. Pulsed laser light is focused and irradiated into a space inside an acoustic waveguide (4), thereby generating pulsed sound waves from the illumination point (7). The pulsed sound waves propagate down the acoustic waveguide as plane waves, then propagate beyond an open end (16) as spherical waves, and break up a foam outside the open end of the acoustic wave guide.

Abstract: Highly specialized three-dimensional structural kinetic mixing particles to promote low surface energy regions for bubble and nucleation sites resulting in stronger, lighter weight foam having consistent cellular structures. The foam composition includes particles that continue to remain active as foam constituent fluids move during the foam expansion process. The continued mixing promotes better dispersion of blowing agents as well as increased mobility through better dispersion of reactive and nonreactive additives throughout the polymer during expansion of the foam thereby improving cellular consistency. The addition of kinetic mixing particles will produce similar results in any structural foam material that uses endothermic blowing agents, exothermic blowing agents and/or gas foam injection systems.
