GEL REMOVED BY VACUUM FOR SURFACE CLEANING, ITS APPLICATION AND METHOD OF SURFACE DECONTAMINATION Russian patent published in 2012 - IPC G21F9/28 

FIELD: power engineering.

SUBSTANCE: gel for surface cleaning contains a colloid solution of the following composition: inorganic modifier of viscosity in the amount of 5-25 wt % of the total mass of gel; surfactants in the amount of less than 0.1 wt %, preferably in the amount from 0.01 to less than 0.1 wt % of the total mass of the gel; inorganic acid or base with concentration of 0.5-7 mole per litre of gel; optionally an oxidant with standard redox potential E0 of more than 1.4 V in a strong-acid medium or a reduced form of this oxidant with concentration of 0.05 - 1 mole per litre of gel; water - balance; besides, the specified gel after complete drying within 2-72 hours at the temperature of 10-30°C and relative moisture of 20-70% is a solid dry residue. There is also a method to decontaminate surfaces and to apply gel.

EFFECT: group of inventions makes it possible to improve available gel for surface cleaning and methods of its application.
