COMPOSITION FOR REMOVING ATMOSPHERIC CORROSION PRODUCTS FROM SURFACE OF CORROSION-RESISTANT STEEL Russian patent published in 2015 - IPC C23G1/02 

FIELD: chemistry.

SUBSTANCE: composition contains orthophosphoric acid, oxalic acid, surfactants in the form of synthanol and an acidic industrial detergent, a disinfecting additive which is a mixture of a disinfectant based on a quaternary ammonium compound, urotropin and hydrochloric acid, as well as silicon oxide and water. Components of the composition are in the following ratio, g/kg: orthophosphoric acid 250-350, oxalic acid 5-10, synthanol 1-6, acidic industrial detergent 5-10, disinfecting additive 10-15, silicon oxide 50-80, water - the balance.

EFFECT: invention provides efficient removal of corrosion products from the surface of large units and components, as well as from a surface of any size and inclination angle, including from an overhead surface, shorter treatment time and disinfection of a treated surface without irritating the surface, while improving fungal resistance thereof, as well as adhesion to paint coats.
