Title
(EN) DECONTAMINATION PASTE AND METHOD FOR DECONTAMINATING A SUBSTRATE MADE OF A SOLID MATERIAL USING SAID PASTE
(FR) PÂTE DE DECONTAMINATION ET PROCEDE DE DECONTAMINATION D'UN SUBSTRAT EN UN MATERIAU SOLIDE UTILISANT CETTE PÂTE
Abstract
(EN)
The invention relates to a decontamination paste comprising at least one inorganic viscosifier selected from clays, at least one compound in the form of fibers and optionally further one or more optional components, the remainder being of solvent. The invention also relates to a method for decontaminating a substrate made of a solid material using said paste, said substrate being contaminated by at least one contaminant species referred to as the labile contaminant species and/or by at least one contaminant species referred to as the surface contaminant species located on one of the surfaces thereof, and/or by at least one contaminant species referred to as the subsurface contaminating species located just below said surface, and/or by at least one contaminant species located under said surface in the depth of the substrate.
(FR)
Pâte de décontamination comprenant au moins un agent viscosant inorganique choisi parmi les argiles, au moins un composé sous la forme de fibres et éventuellement, en outre, un ou plusieurs composant(s) optionnels et le reste de solvant. Procédé de décontamination d'un substrat en un matériau solide à l'aide de ladite pâte, ledit substrat étant contaminé par au moins une espèce contaminante dite espèce contaminante labile et/ou par au moins une espèce contaminante dite espèce contaminante surfacique se trouvant sur une de ses surfaces, et/ou par au moins une espèce contaminante dite espèce contaminante subsurfacique se trouvant juste sous ladite surface, et /ou par au moins une espèce contaminante se trouvant sous ladite surface dans la profondeur du substrat.
