FIELD: inhibitors for prevention of formation of carbonate, sulfate and iron oxide deposits and breaking these deposits in circulating cycles of cooling systems, wet scrubbing of gases, heat supply systems and hydraulic transport facilities. ^ SUBSTANCE: proposed inhibitor contains the following components, mass-%: phosphate inhibitor, 5-40; phosphonate inhibitor, 5-40; anhydrous hygroscopic salt of alkaline or alkaline-earth metals of inorganic acids whose molecule may add-on 4-12 molecules of water, for example, sulfates and carbonates of sodium, potassium, calcium, the remainder being sodium and potassium orthophosphates. Inhibitor contains, mass-%: water-soluble polymer (molecular mass 3000-20000), 5-40; anhydrous hygroscopic salt of alkaline or alkaline-earth metals of inorganic acids whose molecule may add-on 4-12 molecules of water, for example sulfates and carbonates of sodium, potassium and calcium; the remainder being sodium and potassium orthophosphates. ^ EFFECT: possibility of obtaining inhibitor in solid state in form of tablets or granules due to improved contact of particles. ^ 9 cl, 3 ex |
