DECONTAMINATING, CLEANING AND/OR DEGREASING FOAM CONTAINING SOLID PARTICLES Russian patent published in 2012 - IPC C11D3/02 C11D3/37 C11D17/00 G21F9/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to decontaminating, cleaning and degreasing surfaces. The foam consists of a dispersion of air bubbles in a foaming aqueous solution containing: 0.1-7 mol of one or more decontaminating, cleaning and/or degreasing reactant per litre of the solution, 0.01-25 wt % with respect to total weight of the solution of solid particles of the same type or mixtures of solid particles of different types, having foaming properties. The method of producing the foam involves mixing a decontaminating, cleaning and/or degreasing active agent, solid particles having foaming properties and, optionally, a surfactant, an oxidising agent, a complexing agent, a gelating agent and/or a solid foaming agent and/or solid particles having sorption properties before generating foam.

EFFECT: increasing foam life to 24 hours, which provides higher efficiency of decontaminating, cleaning and/or degreasing surfaces.
