Abstract
A stabilized foam formed from a foaming aqueous solution comprising from 0.1 to 7 mol of one or more decontamination, stripping and/or degreasing reactants per liter of solution and from 0.01 to 15% by weight of a solid stabilizing agent of solid particles type, with respect to the total weight of the solution, and a process for the preparation of said stabilized foam, to its use in decontaminating, stripping and/or degreasing a surface and to a process for decontaminating, stripping and/or degreasing a surface.
Claims7
A stabilized foam composed of a dispersion of bubbles of air in a foaming aqueous solution, comprising:
- from 0.1 to 7 mol of one or more decontamination, stripping and/or degreasing agent per liter of solution;
- and
- from 0.01 to 25% by weight with respect to the total weight of the solution, of solid particles of identical nature or of mixtures of solid particles of different nature, said solid particles presenting foaming properties,
- wherein said solid particles presenting foaming properties are solid entirely mineral particles functionalized by having hydrophobic organic molecules grafted thereon.
A process for the preparation of a stabilized foam composed of a dispersion of bubbles of air in a foaming aqueous solution, the process comprising:
- mixing together from 0.1 to 7 mol of one or more decontamination, stripping and/or degreasing agent per liter of solution;
- and from 0.01 to 25% by weight with respect to the total weight of the solution, of solid particles of identical nature or of mixtures of solid particles of different nature, said solid particles presenting foaming properties, wherein said solid particles presenting foaming properties are solid entirely mineral particles functionalized by having hydrophobic organic molecules grafted thereon.
