FIELD: chemical industry; other industries; production of compositions for cleaning the firm surfaces.
SUBSTANCE: the invention is pertaining to the field of production of the cleansing substances, in particular, to the substances for removal of the scaling and may be used in the form of the water solutions for cleaning both the heat-and-power power installations, the technological equipment (pasteurizers, sterilizers, etc.) and the heat-exchange equipment made out of the corrosion-proof ferrous and non-ferrous metals, and the domestic enameled or plastic houseware. The powdery water- soluble composition contains (in mass %): carbamide-phosphate - 5-99, sodium salt of carboxymethyl cellulose - 1-5. The composition may additionally contain - 0.1-1.0 mass % (over 100 mass %) of laprol. The technical result of the invention is prevention of corrosion of the metallic surfaces without reduction of efficiency of the cleaning.
EFFECT: the invention ensures prevention of corrosion of the metallic surfaces without reduction of efficiency of the cleaning.
