<p>The invention relates to washing agents for removing various impurities, including hydrocarbon compositions, from various objects including metallic objects. The inventive detergent comprises (mass %): 50-94 mass % water-soluble alkali salt, 3-20 mass % non-ionic surface-active substance, 1-8 mass % sodium salt of polyacrylic acid modified by ether groups, 0.5-15 mass % rust inhibitor, 1-5 mass % dispersing agent, 0.1-1 mass % antifoamer, the rest being water. A substance containing a polyethylene glycol having a molar weight ranging from 400 to 15000 is used as a dispersing agent. A polydimethyl siloxane of general formula (CH)3 Si [OSi (CH3)2]n OSi(CH3)3, where n = 3-700, or tributyl phosphate is used as an antifoamer. Said invention increases the detergent power, extends the temperature range for using the inventive detergent and makes it possible to control the dispersing, emulsionising and de-emulsionising properties of a washing solution. In addition, a formed monomolecular polymeric film prevents corrosion of material.</p> |
