| description | FIELD: cleaning of systems of hot-water supply for mineral deposits. SUBSTANCE: method includes introduction of aqueous suspension of cationite èô-2, adding of 1-100 mg equiv./l of soluble salt of alkali metal, heating of system up to 60-100 C, connecting to air line in moderate conditions of stirring of medium with pH 1-3. EFFECT: provision of removal of dense deposits 1 mm thick from closed volumes of heat exchange equipment operating on water with temporary or constant hardness with minimum labor input and time. 3 cla |
